Zigbee2Tasmota serves as a gateway for devices connected to a Zigbee wireless network to bridge their communications over to Wi-Fi

Zigbee2Tasmota is a lightweight Zigbee solution running on an ESP82xx Wi-Fi chip. Hence it is easier to deploy wherever you want in your home. It is largely inspired by Zigbee2mqtt but it's a complete rewrite to make it fit on an ESP82xx with 80kB of RAM and only 1MB of flash memory.

A list of compatible coordinators and Zigbee devices is maintained in the Zigbee Device Compatibility Repository.

Zigbee Introduction~

Before using Zigbee to Tasmota, you need to understand a few concepts. Here is a simplified comparison to the Wi-Fi equivalent (sort of).

Zigbee concept Wi-Fi equivalent
Zigbee coordinator
The coordinator is responsible for selecting the channel, PanID, security policy, and stack profile for a network. Zigbee2Tasmota will act as a coordinator.
You can have multiple coordinators as long as they have different PanIDs.
Wi-Fi Access Point
(Personal Area Network IDentifier)
This parameter is unique in a Zigbee network (16-bit integer, 0x0000–0x3FFF).
Default: 0x1A63
SSID (the Wi-Fi network name)
Address of the device on the Zigbee network. This address is randomly assigned when the device first connects to the coordinator (16 bits integer, 0x0000–0xFFF7). The coordinator has address 0x0000.
You need to track which device has which address or assing a "Friendly Name" to each new discovered device.
IP address
Group address of a collection of devices, it allows a single message to address multiple devices at once (16 bits integer, 0x0000–0xFFFF). For example a remote can turn on/off a group of lights. GroupAddr 0x0000 is not assigned.
The endpoint on the coordinator or on the Zigbee device the message is sent from/to. You can see endpoints as logical device providing distinct features (8 bits integer, 1–240).
IP Port
Device hardware address (64 bits). This is unique per device and factory assigned.
MAC address
Channel 11-26
Default: 11 (See Zigbee-Wifi coexistence)
Wi-Fi Channel
Encryption Key
128-bit encryption key.
default: 0x0D0C0A08060402000F0D0B0907050301
Wi-Fi password
By default the coordinator does not accept new devices unless put in pairing mode. When in pairing mode, it will accept pairing requests from any device within range.
Default: pairing disabled
Clusters are a group of commands and attributes that define what a device can do. Think of clusters as a group of actions by function. A device can support multiple clusters to do a whole variety of tasks. The majority of clusters are defined by the ZigBee Alliance and listed in the ZigBee Cluster Library

Required Hardware~

Zigbee Adapter

Any TI CC2530 or CC2531 chip based module can serve as a coordinator. See list of supported modules with their pinouts and flashing instructions.

These PCBs make all the connections required to flash the CC2530 and to run Z2T:

Jon Oxer created a custom PCB to connect a Wemos D1 Mini and a CC2530 board (with or without CC2591).

Complete module


User h4nc created a custom PCB to connect a NodeMCU and a CC2530 board.

You can also get a complete Z2T module with case, pre-flashed and ready to configure and deploy.

Wi-Fi Adapter

Using an ESP82xx device such as a Wemos D1 Mini or a NodeMCU to flash the CC2530 is a lower cost alternative than using a single purpose CC_DEBUGGER.

In normal operation two free GPIOs are needed for the serial communication with the CC2530.


Flash Zigbee Adapter~

Zigbee2Tasmota requires a TI CC2530 based module flashed with Z-Stack CC2530 firmware file from Koen Kanters.

Due to memory constraints of the CC2530, you can only pair 16 devices to a coordinator (See details).


There is an alternative firmware allowing for Zigbee routers to create a mesh network and go beyond 16 devices. This is currently not tested nor supported by Zigbee2Tasmota. It may be added later.

Flashing options:

  • Flashing with CCLoader and ESP8266 (recommended)
  • Flashing with CCLib and ESP8266
  • Flash with a dedicated CC Debugger and PC

Flash Tasmota~

Once the flashing process completes, you can re-use the ESP82xx and flash Tasmota with Zigbee2Tasmota enabled firmware. Otherwise, you can use any ESP82xx device.

Zigbee feature is not included in precompiled binaries

To use it you must compile your build. Add the following to user_config_override.h:

#define USE_ZIGBEE 


Run the ESP at 160MHz instead of 80MHz which ensures higher reliability in serial communication with CC2530.

In platformio_override.ini uncomment line 51:

board_build.f_cpu = 160000000L

If you find that your Zigbee2Tasmota operation is unstable, you may have an ESP82xx device that cannot operate reliably at the higher frequency. If you are using hardware serial (see below) and you still have unreliability, try compiling for 80MHz (reverse the options above) and flash the ESP82xx device again to see if operating at a lower frequency improves stability. Running at 80MHz will impact software serial communications so hardware serial is highly recommended if running the ESP82xx at 80MHz.

Flash the newly compiled binary usig the normal flashing process.

Connect CC2530 to Tasmota~

If you are using your ESP82xx device to flash the Zigbee adapter as described in tutorials you may want to leave these connections in place in case you ever need to update Zigbee firmware. If not, any of the free GPIOs can be used.

It is recommended that hardware serial pins be used (GPIO1/GPIO3 or GPIO13[Rx]/GPIO15[Tx])

Due to ESP82xx GPIO pin constraints, GPIO15 can only be used as serial Tx.

The interface between the ESP82xx Wi-Fi device and the Zigbee module uses high speed serial.


Tasmota also provides serial communications emulation through software (i.e., software serial). This allows any GPIO to be used. TasmotaSerial version 2.4.x (PR #6377) has improved the reliability of software serial making it feasible for use in this application. However, if you have an option to use hardware serial, choose that.

Z2T uses software serial by default to allow for serial logging on GPIO1/GPIO3

Use SerialLog 0 to enable hardware serial on GPIO13[Rx]/GPIO15[Tx].

Recommended wiring:

Zigbee Module
GPIO13 Zigbee RX (166) CC_TXD
(A.K.A. P0_3)
GPIO15 Zigbee TX (165) CC_RXD
(A.K.A. P0_2)

Tasmota Settings~

In the Configuration -> Configure Module page assign:

  • GPIO13 to Zigbee RX (166)
  • GPIO15 to Zigbee TX (165)

You can quickly configure Tasmota using a custom template instead.

Use this one for the recommended wiring scheme:


First Run~

When the Tasmota device boots, Zigbee2Tasmota will wait for 15 seconds before initializing the CC2530. This time allows for Wi-Fi and MQTT to connect (hopefully).

First boot:

MQT: tele/%topic%/RESULT = {"ZbState":{"Status":1,"Message":"CC2530 booted","RestartReason":"Watchdog","MajorRel":2,"MinorRel":6}}
MQT: tele/%topic%/RESULT = {"ZbState":{"Status":50,"MajorRel":2,"MinorRel":6,"MaintRel":3,"Revision":20190608}}
MQT: tele/%topic%/RESULT = {"ZbState":{"Status":2,"Message":"Reseting configuration"}}
MQT: tele/%topic%/RESULT = {"ZbState":{"Status":3,"Message":"Configured, starting coordinator"}}
MQT: tele/%topic%/RESULT = {"ZbState":{"Status":51,"IEEEAddr":"0x00124B00199DF06F","ShortAddr":"0x0000","DeviceType":7,"DeviceState":9,"NumAssocDevices":0}}
MQT: tele/tasmota/Zigbee_home/RESULT = {"ZbState":{"Status":0,"Message":"Started"}}
ZIG: Zigbee started
ZIG: No zigbee devices data in Flash

Zigbee will automatically boot the CC2530 device, configure the device and wait for Zigbee messages.

Normal boot looks like:

MQT: tele/%topic%/RESULT = {"ZbState":{"Status":1,"Message":"CC2530 booted","RestartReason":"Watchdog","MajorRel":2,"MinorRel":6}}
MQT: tele/%topic%/RESULT = {"ZbState":{"Status":50,"MajorRel":2,"MinorRel":6,"MaintRel":3,"Revision":20190608}}
MQT: tele/%topic%/RESULT = {"ZbState":{"Status":3,"Message":"Configured, starting coordinator"}}
MQT: tele/%topic%/RESULT = {"ZbState":{"Status":51,"IEEEAddr":"0x00124B00199DF06F","ShortAddr":"0x0000","DeviceType":7,"DeviceState":9,"NumAssocDevices":0}}
MQT: tele/%topic%/RESULT = {"ZbState":{"Status":0,"Message":"Started"}}
ZIG: Zigbee started
ZIG: Zigbee devices data in Flash (516 bytes)

You can force a factory reset of your CC2530 with ZigbeeReset 1 and reboot


For a list of available command see Zigbee Commands.

Pairing Zigbee Devices~

When you first create a Zigbee network, it contains no device except the coordinator. The first step is to add devices to the network, which is called pairing.

By default, and for security reasons, the Zigbee coordinator does not automatically accept new devices. To pair new devices, use ZbPermitJoin 1. Once Zigbee2Tasmota is in pairing mode, put the Zigbee device into pairing mode. This is usually accomplished by pressing the button on the device for 5 seconds or more. To stop pairing, use ZbPermitJoin 0.

ZbPermitJoin 1

CMD: ZbPermitJoin 1
MQT: stat/%topic%/RESULT = {"ZbPermitJoin":"Done"}
MQT: tele/%topic%/RESULT = {"ZbState":{"Status":21,"Message":"Enable Pairing mode for 60 seconds"}}

60 seconds later:

MQT: tele/%topic%/RESULT = {"ZbState":{"Status":20,"Message":"Disable Pairing mode"}}

Although this is highly discouraged, you can permanently enable Zigbee pairing, until the next reboot, with ZbPermitJoin 99.

ZbPermitJoin 99

MQT: tele/%topic%/RESULT = {"ZbState":{"Status":22,"Message":"Enable Pairing mode until next boot"}}

ZbPermitJoin 0
MQT: tele/%topic%/RESULT = {"ZbState":{"Status":20,"Message":"Disable Pairing mode"}}
MQT: tele/%topic%/SENSOR = {"ZbState":{"Status":30,"IEEEAddr":"0x00158D00036B50AE","ShortAddr":"0x8F20","PowerSource":false,"ReceiveWhenIdle":false,"Security":false}}

Example for Aqara Temperature & Humidity Sensor

To pair this sensor, press and hold the button for 5 seconds. The led will flash several times and you will see logs entries, especially this one:

  1. Put Zigbee2Tasmota into pairing mode using the ZigbeePermitJoin command as described above
  2. Press the Xiaomi Aqara sensor's button for 5 seconds to pair the devices. You will see a message as follows:

MQT: tele/%topic%/SENSOR = {"ZbState":{"Status":30,"IEEEAddr":"0x00158D00036B50AE","ShortAddr":"0x8F20","PowerSource":false,"ReceiveWhenIdle":false,"Security":false}}

Message with "Status":30 shows some characteristics of the device:

Field name Value
Status 30 indicates a device connect or reconnect. This is the opportunity to match IEEEAddress and short address
IEEEAddr Long unique address (64 bits) of the device - factory set
ShortAddr Short address (16 bits) randomly assigned to the device on this Zigbee network
PowerSource true = the device is connected to a power source
false = the device runs on battery
ReceiveWhenIdle true = the device can receive commands when idle
false = the device is not listening. Commands should be sent when the device reconnects and is idle
Security Security capability (meaning unknown, to be determined)

Zigbee Friendly Names~

Supported since version 8.2!

Instead of a short address like "0x4773" you can assign a memorable friendly name like "Room_Plug".

See ZbName command to set names.

Xiaomi Aqara Cube with address 0x128F

MQT: tele/%topic%/RESULT = {"ZbReceived":{"0x128F":{"AqaraVibrationMode":"tilt","AqaraVibrationsOrAngle":162,"AqaraAccelerometer":[-690,2,138],"AqaraAngles":[-78,0,11],"LinkQuality":158}}}

Setting its friendly name to Vibration_sensor:

ZbName 0x128F,Vibration_sensor
CMD: ZbName 0x128F,Vibration_sensor
MQT: stat/%topic%/RESULT = {"0x128F":{"Name":"Vibration_sensor"}}

(10 seconds later)
ZIG: Zigbee Devices Data store in Flash (0x402FF800 - 270 bytes)

Now the sensor readings includes the friendly name:

MQT: tele/%topic%/RESULT = {"ZbReceived":{"0x128F":{"Name":"Vibration_sensor","AqaraVibrationMode":"tilt","AqaraVibrationsOrAngle":171,"AqaraAccelerometer":[-691,12,130],"AqaraAngles":[-78,1,11],"LinkQuality":153}}}

If you set SetOption83 1 sensor readings will use the friendly name as KSON key, short address is added as Device:

MQT: tele/%topic%/RESULT = {"ZbReceived":{"Vibration_sensor":{"Device":"0x128F","AqaraVibrationMode":"tilt","AqaraVibrationsOrAngle":171,"AqaraAccelerometer":[-691,8,136],"AqaraAngles":[-78,1,11],"LinkQuality":153}}}

Reading Sensors~

Most sensors will spontaneously publish their readings, regularly or once a signifcant change happened: temperature, pressure, humidity, presence, illuminance...

Sensor messages are published via MQTT when they are received from the Zigbee device. Similar to Zigbee2MQTT, Z2T tries to group and debounce sensor values when they are received within a 300ms window.

Aqara Temperature & Humidity Sensor

This sensor monitors humidity, temperature, and air pressure. Its Zigbee model ID is

This device publishes sensor values roughly every hour or when a change occurs. You can also force an update pressing the device's button. It sends two kinds of messages, either 3x standard Zigbee messages, or a single proprietary message containing all sensor values.

0x8F20 is the ShortAddress of the sensor, and its name is Kitchen if you used ZbName 0x8F20,Kithchen.

MQT: tele/%topic%/SENSOR ={"ZbReceived": {"0x8F20": {"Name": "Kitchen", "Voltage": 2.995, "Battery": 98, "Temperature": 21.01, "Humidity": 53.68, "Pressure": 1004.04, "PressureUnit": "hPa", "Endpoint": 1, "LinkQuality": 88}}

or prefixed by name if you set SetOption83 1

MQT: tele/%topic%/SENSOR ={"ZbReceived": {"Kitchen": {"Device": "0x8F20", "Voltage": 2.995, "Battery": 98, "Temperature": 21.01, "Humidity": 53.68, "Pressure": 1004.04, "PressureUnit": "hPa", "Endpoint": 1, "LinkQuality": 88}}

Topic is device specific, to allow more effective retained messages, if you set SetOption89 1

MQT: tele/%topic%/8F20/SENSOR ={"ZbReceived": {"Kitchen": {"Device": "0x8F20", "Voltage": 2.995, "Battery": 98, "Temperature": 21.01, "Humidity": 53.68, "Pressure": 1004.04, "PressureUnit": "hPa", "Endpoint": 1, "LinkQuality": 88}}

Supported values:

Field name Value
LinkQuality Stength of the Zigbee signal, between 1 and 254 (integer). See this ZigBee and WiFi Coexistence
Humidity Humidity in percentage (float)
Pressure and PressureUnit Atmospheric pressure (float) and unit (string)
Currently only hPa (A.K.A. mbar) is supported
Temperature Temperature in Celsius (float)
Voltage Battery voltage (float)
Battery Battery charge in percentage (integer)
ModelId Model name of the Zigbee device (string)
ScaledValue and Scale Give the raw measure and the scale correction as 10^scale
And many more...

If a value is not decoded, it will appear as "<cluster>_<attr>":<value> where <cluster> is the Zigbee ZCL Cluster of the attribute (family), <attr> is the attribute number and <value> its published value.


"0402_0000":2240 is attribute 0x0000 from cluster 0x0402, which is the temperature in hundredth of °C. It is automatically converted to "Temperature":22.40.

Device Information~

You can dump the internal information gathered about connected Zigbee devices with the command ZigbeeStatus.

You can use ZbStatus2 to display all information and endpoints. If probing was successful (at pairing time or using ZbProbe), Tasmota will automatically find the right endpoint.

Depending on the number of device you have, ZbStatus2 output can exceed tha maximum MQTT message size. You can request the status of each individual device using ZbStatus2 1, ZbStatus2 2, ZbStatus2 3...

ZbStatus1 - List all connected devices


ZbStatus2 - Display detailed information for each device, including long address, model and manufacturer:

{"ZbStatus2":[{"Device":"0x4773","IEEEAddr":"0x7CB03EAA0A0292DD","ModelId":"Plug 01","Manufacturer":"OSRAM","Endpoints":["0x03"]},{"Device":"0x135D","Name":"Temp_sensor","IEEEAddr":"0x00158D00036B50AE","ModelId":"","Manufacturer":"LUMI","Endpoints":["0x01"]}]}

(formatted for readability)

    "ZbStatus2": [{
        "Device": "0x4773",
        "IEEEAddr": "0x7CB03EAA0A0292DD",
        "ModelId": "Plug 01",
        "Manufacturer": "OSRAM",
        "Endpoints": ["0x03"]
    }, {
        "Device": "0x135D",
        "Name": "Temp_sensor",
        "IEEEAddr": "0x00158D00036B50AE",
        "ModelId": "",
        "Manufacturer": "LUMI",
        "Endpoints": ["0x01"]

Understanding Endpoints~

The endpoint on the coordinator or on the Zigbee device the message is sent from/to.

Z2T will automatically take the first endpoint in the list; this works most of the time. You normally don't need to specify the endpoint number. In rare case, you can still force a specific endpoint.

Example Endpoints:

Device Endpoint
OSRAM Plug 0x03
Philips Hue Bulb 0x0B

Sending Commands~

You can send commands to device or groups of device, for example to turn on/off a light, set its brightness of open/close shutters.

Here is a list of supported commands, see below how to send any command if it's not in the list.

Command Parameters Cluster
Power 1\|true\|"true"\|"on": On
0\|false\|"false"\|"off": Off
2\|"Toggle": Toggle
Dimmer 0..254: Dimmer value
255 is normally considered as invalid, and may be converted to 254
DimmerUp null: no parameter. Increases dimmer by 10% 0x0008
DimmerDown null: no parameter. Decreases dimmer by 10% 0x0008
DimmerStop null: no parameter. Stops any running increase of decrease of dimmer. 0x0008
ResetAlarm <alarmcode>,<clusterid>: (to be documented later) 0x0009
ResetAllAlarms null: no parameter, (to be documented later) 0x0009
Hue 0..254: change Hue value 0x0300
Sat 0..254: change Sat value 0x0300
HueSat 0..254,0..254: change both Hue and Sat values 0x0300
Color 0..65534,0..65534: change the color using [x,y] coordinates 0x0300
CT 0..65534: change the white color-temperature in Mireds 0x0300
Shutter 0..254: send any Shutter command (prefer the commands below) 0x0102
ShutterOpen null: no parameter, open shutter 0x0102
ShutterClose null: no parameter, close shutter 0x0102
ShutterStop null: no parameter, stop shutter movement 0x0102
ShutterLift 0..100: move shutter to a specific position in percent
0%=open, 100%=closed
ShutterTilt 0..100: move the shutter to the specific tilt position in percent 0x0102

The format of the command is following:

ZbSend {"Device":"<device>","Send":{"<sendcmd>":<sendparam>}} where
<device>identifies the target and can be a shortaddr 0x1234, a longaddr 0x1234567812345678 or a name Kitchen.
"<sendcmd>":<sendparam> the command and its parameters

If the device has been correctly paired and its endpoints recorded by Z2T, you shouldn't need to specify a target endpoint. You can use an option "endpoitn":<endpoint> parameter if Z2T can't find the correct endpoint or if you want to change from the default endpoint. See below Understanding endpoints.

Low-level Commands~

There is a special syntax if you want to send arbitrary commands: "Send":"<send_bytes>" where <send_bytes> has the following syntax:

"<cluster>_<cmd>/<bytes>": send a non-cluster specific command for cluster id <cluster>, command id <cmd> and payload <bytes>.

Example: ZbSend {"Device":"0x1234","Send":"0000_00/0500"} I.e. send a Read command (0x00) to the general cluster (0x0000) for attribute ManufId (0x0005). Note: all values are little-endian.

Or use '!' instead of '_' to specify cluster-specific commands:

"<cluster>!<cmd>/<bytes>": send a cluster specific command for cluster id <cluster>, command id <cmd> and payload <bytes>.

Example: ZbSend {"Device":"0x1234","Send":"0008_04/800A00"} I.e. send a Dimmer command (0x04) from Level Control cluster (0x0008) with payload being: Dimmer value 0x80, and transition time of 1 second (0x000A = 10 tenths of seconds).

Of course the latter example could be simply: ZbSend {"Device":"0x1234","Send":{"Dimmer":"0x80"}



ZbSend { "device":"0x4773", "send":{"Power":"On"} }
ZbSend { "device":"0x4773", "send":{"Power":1} }
ZbSend { "device":"0x4773", "send":{"Power":false} }
ZbSend { "device":"0x4773", "send":{"Power":"Toggle"} }

Read the On/Off status: (all three commands below are synonyms)

ZbRead { "device":"0x4773", "endpoint":"0x03", "cluster":"0x0006", "read":"0x0000" }
ZbRead { "device":"0x4773", "endpoint":"0x03", "cluster":"0x0006", "read":["0x0000"] }
ZbRead { "device":"0x4773", "endpoint":3, "cluster":6, "read":0 }
MQT: tele/tasmota/SENSOR = {"ZbReceived":{"0x4773":{"Power":true,"LinkQuality":52}}}

Philips Hue bulb

ZbSend { "device":"0x3D82", "send":{"Power":"Off"} }
ZbSend { "device":"0x3D82", "send":{"Dimmer":128} }
ZbSend { "device":"0x3D82", "send":{"Dimmer":254} }
ZbSend { "device":"0x3D82", "endpoint":"0x0B", "send":{"Dimmer":0} }

Receiving Commands~

If you pair device like switches and remotes, you will also see received commands from thos devices.

When a command is received, attributes are published both in their low-level and high-level formats (if known).

Low level format is the following: "<cluster>!<cmd>":"<payload"

Example for IKEA Remote: {"ZbReceived":{"IKEA_remote":{"Device":"0xF72F","0006!02":"","Power":2,"Endpoint":1,"LinkQuality":31}}}

The command received "0006!02":"" is Power Toggle (0x02) from On/Off cluster (0x0006) with no payload. It is also translated as "Power":2. "Endpoint":1 tells you from which endpoint the command was send. Some Xiaomi multi-switches use different endpoints for each switch.

Light State Tracking

Once Z2T receives a command related to a light (Power, Dimmer, Color, ColorTemp), it sends right after a Read command to get the actual state of the light. This is used for Hue Emulation and Alexa support. The final attributes are read betwenn 200ms and 1000ms later, to allow for the light to achieve its target state.

  • Long press dimmer down release - ,"0008!03":"0000" and "DimmerStop":true

Zigbee Groups~

Zigbee has a unique feature call Groups. It allows you to send a single command to a group of devices. For example a remote can control a group of multiple lights.

Zigbee groups are 16 bits arbitrary numbers that you can freely assign. When you send to a group, you don't specify a targer address anymore nor an endpoint.

Groups works in two steps: first you add devices to groups, second you send commands to groups. See the below Zigbee Binding to configure a remote to send commands to a specific group.

Configuring groups for devices requires to send commands. Make sure the device is powered and awake (i.e. wake-up battery powered devices).

List all groups for a device.

ZbSend {"device":"IKEA_Light","Send":{"GetAllGroups":true}}

MQT: tele/%topic%/SENSOR = {"ZbReceived":{"IKEA_Light":{"Device":"0x5ADF","0004<02":"FF00","GetGroupCapacity":255,"GetGroupCount":0,"GetGroup":[],"Endpoint":1,"LinkQuality":80}}}

The following response tells you: "GetGroupCount":1 the light belongs to one group "GetGroup":[100] and the group number is 100.

MQT: tele/%topic%/SENSOR = {"ZbReceived":{"IKEA_Light":{"Device":"0x5ADF","0004<02":"FF016400","GetGroupCapacity":255,"GetGroupCount":1,"GetGroup":[100],"Endpoint":1,"LinkQuality":80}}}

Add a group to a device

ZbSend {"device":"IKEA_Light","Send":{"AddGroup":100}}

MQT: tele/%topic%/SENSOR = {"ZbReceived":{"IKEA_Light":{"Device":"0x5ADF","0004<00":"006400","AddGroup":100,"AddGroupStatus":0,"AddGroupStatusMsg":"SUCCESS","Endpoint":1,"LinkQuality":80}}}

Or if the group already exists:

MQT: tele/%topic%/SENSOR = {"ZbReceived":{"IKEA_Light":{"Device":"0x5ADF","0004<00":"8A6400","AddGroup":100,"AddGroupStatus":138,"AddGroupStatusMsg":"DUPLICATE_EXISTS","Endpoint":1,"LinkQuality":80}}}

Remove a group

ZbSend {"device":"IKEA_Light","Send":{"RemoveGroup":100}}

MQT: tele/%topic%/SENSOR = {"ZbReceived":{"IKEA_Light":{"Device":"0x5ADF","0004<03":"006400","RemoveGroup":100,"RemoveGroupStatus":0,"RemoveGroupStatusMsg":"SUCCESS","Endpoint":1,"LinkQuality":80}}}

or if the group does not exist

MQT: tele/%topic%/SENSOR = {"ZbReceived":{"IKEA_Light":{"Device":"0x5ADF","0004<03":"8B6400","RemoveGroup":100,"RemoveGroupStatus":139,"RemoveGroupStatusMsg":"NOT_FOUND","Endpoint":1,"LinkQuality":80}}}

Remove all groups

ZbSend {"device":"IKEA_Light","Send":{"RemoveAllGroups":true}}

MQT: tele/%topic%/SENSOR = {"ZbResponse":{"Device":"0x5ADF","Name":"IKEA_Light","Command":"0004!04","Status":0,"StatusMessage":"SUCCESS","Endpoint":1,"LinkQuality":80}}

Sending commands to a group

Just use the attribute "Group":<group_id> instead of "Device":<device> when sending a command.


  • power on all light in group 100: ZbSend {"group":100,"Send":{"Power":1}}
  • set all dimmers in group 100 to 50%: ZbSend {"group":100,"Send":{"Dimmer":127}}

Zigbee Binding~

Binding allows a device to send command to another device in the same Zigbee network, without any additional logic. For example, you can set a remote to control directly a group of lights, without any rules on the coordinator. The coordinator will still receive all commands.

Example of direct binding ZbBind {"Device":"0xC2EF","ToDevice":"0x5ADF","Endpoint":1,"ToEndpoint":1,"Cluster":6}

This command links the device 0xC2EF that will send all commands for cluster 6 (On/off cluster) frome endpoint 1 to the target device 0x5ADF on endpoint 1.

Example of group binding ZbBind {"Device":"0xC2EF","ToGroup":100,"Endpoint":1,"Cluster":6}

This command links the device 0xC2EF that will send all commands for cluster 6 (On/off clustre) and from endpoint 1 to the group 100.

Reponse in case of success:

MQT: tele/%topic%/RESULT = {"ZbBind":{"Device":"0xF72F","Name":"IKEA_Remote","Status":0,"StatusMessage":"SUCCESS"}}

Example: IKEA remote and IKEA Light

IKEA remotes only support 1 group, and can be linked to a light only via group numbers (no direct binding).

  1. Add the light to group 100 ZbSend {"device":"IKEA_Light","Send":{"AddGroup":100}}

  2. Bind the remote to group 100. Note: you need to press a button on the remote right before sending this command to make sure it's not in sleep mode ZbBind {"Device":"IKEA_Remote","ToGroup":100,"Endpoint":1,"Cluster":6}

Zigbee and Hue Emulation for Alexa~

Z2T now supports Hue Emulation for Zigbee lights. It will mimic most of Zigbee gateways, and allows you to control Zigbee lights directly with Alexa, without any MQTT broker nor Alexa skill.

Command ZbLight configures a Zigbee device to be Alexa controllable. Specify the number of channels the light supports:

  • 0 Simple On/Off light
  • 1 White Light with Dimmer
  • 2 White Light with Dimmer and Cold/Warm White
  • 3 RGB Light
  • 4 RGBW Light
  • 5 RGBCW Light, RGB and Cold/Warm White

To set the light, use ZbLight <device>,<nb_of_channels. Ex:

ZbLight 0x1234,2
ZbLight Kitchen_Light,1   (see ZbName)

Once a light is declared, Z2T will monitor any change made to the light via Z2T or via remotes, either from a direct message or via a group message. Z2T will then send a read command to the light, between 200ms and 1000ms later, and memorize the last value.

To read the last known status of a light, use ZbLight <device>


ZbLight Kitchen_Light
MQT: stat/%topic%/RESULT = {"ZbLight":{"Kitchen_Light":{"Device":"0x5ADF","Light":2,"Power":0,"Dimmer":130,"Colormode":2,"CT":350}}}

Specific Device Configuration~

If your device pairs successfully with Zigbee2Tasmota but doesn't report on standardized endpoint you will see messages like these:

In this case you will have to use rules or an external home automation solution to parse the ZbReceived messages. The following section will focus only on rules to utilize the device inside Tasmota ecosystem.

Ikea ON/OFF Switch~

"ModelId":"TRADFRI on/off switch","Manufacturer":"IKEA of Sweden"

  • Short press O - 0006!00
  • Short press I - 0006!01
  • Long press O - 0008!01
  • Long press I - 0008!05
  • Long press release O or I - 0008!07

In this example Tradfri switch reports on 0x7596 and is used to control another Tasmota light device:

  on ZbReceived#0x7596#0006!00 do publish cmnd/%topic%/POWER OFF endon 
  on ZbReceived#0x7596#0006!01 do publish cmnd/%topic%/POWER ON endon 
  on ZbReceived#0x7596#0008!01 do publish cmnd/%topic%/Dimmer - endon 
  on ZbReceived#0x7596#0008!05 do publish cmnd/%topic%/Dimmer + endon

Aqara Water Leak Sensor~


In this example sensor reports on 0x099F and sends an mqtt message to topic stat/leak_sensor/LEAK:

  on ZbReceived#0x099F#0500!00=010000FF0000 do publish stat/leak_sensor/LEAK ON endon 
  on ZbReceived#0x099F#0500!00=000000FF0000 do publish stat/leak_sensor/LEAK OFF endon 

Aqara Vibration Sensor~


To modify sensor sensitivity use command. Replace "device" with your own device name:

# for high sensitivity
ZbSend {"device":"vibration","Endpoint":1,"Cluster":0,"Manuf":"0x115F","Write":{"0000/FF0D%20":"0x01"}} 
# for medium sensitivity
ZbSend {"device":"vibration","Endpoint":1,"Cluster":0,"Manuf":"0x115F","Write":{"0000/FF0D%20":"0x0B"}} 
# for low sensitivity
ZbSend {"device":"vibration","Endpoint":1,"Cluster":0,"Manuf":"0x115F","Write":{"0000/FF0D%20":"0x15"}}

Command needs to be issued shortly after pressing the device button. There will be no response to the command but you can check if the new option is active by using

ZbSend {"Device":"vibration","Endpoint":1,"Cluster":0,"Manuf":"0x115F","Read":"0xFF0D"}

Received response will be :


"0000/FF0D" is the key, value 1 is high sensitivity, 11 medium and 21 is low.

Zigbee2Tasmota Status Codes~

You can inspect the log output to determine whether Zigbee2Tasmota started correctly. Zigbee2Tasmota sends several status messages to inform the MQTT host about initialization.

{"ZbState":{"Status":1,"Message":"CC2530 booted","RestartReason":"Watchdog","MajorRel":2,"MinorRel":6}}
  • Status contains a numeric code about the status message
    • 0: initialization complete, Zigbee2Tasmota is running normally
    • 1: booting
    • 2: resetting CC2530 configuration
    • 3: starting Zigbee coordinator
    • 20: disabling Permit Join
    • 21: allowing Permit Join for 60 seconds
    • 22: allowing Permit Join until next boot
    • 30: Zigbee device connects or reconnects
    • 31: Received Node Descriptor information for a Zigbee device
    • 32: Received the list of active endpoints for a Zigbee device
    • 33: Received the simple Descriptor with active ZCL clusters for a Zigbee device
    • 50: reporting CC2530 firmware version
    • 51: reporting CC2530 device information and associated devices
    • 98: error, unsupported CC2530 firmware
    • 99: general error, Zigbee2Tasmota was unable to start
  • Message (optional) a human-readable message
  • other fields depending on the message (e.g., Status=50 or Status=51)
