Commands

Commands can be issued using MQTT, web requests, webUI console and serial

How to use~

Every command used without a parameter (payload) returns the current setting.

Power returns the status of first defined power output (usually Relay1)"

Instead of 0 you can use off or false and instead of 1 you can use on or true.

Power ON turns first defined power output (usually Relay1) on

Power1 1 also turns first defined power output (usually Relay1) on

Power1 True also turns first defined power output (usually Relay1) on

Replace <x> in a command with the appropriate index number. Leave it empty to use the first available.

Power1 and Power both control first defined power output (usually Relay1)

In commands with x..y value parameters use a number from x to y range.

When a command mentions resetting to "firmware default" it means the setting will revert to the one in the flashed binary file. If you used user_config_override.h at compile time it will revert to those.

with MQTT~

To send commands and view responses you'll need an MQTT client.

Commands over MQTT are issued by using cmnd/%topic%/<command> <parameter> where %topic% is the topic of the device you're sending the command to. If there is no <parameter> (an empty MQTT message/payload), a query is sent for current status of the <command>.

See MQTT article to find out more.

with Web Requests~

Commands can be executed via web (HTTP) requests, for example:

http://<ip>/cm?cmnd=Power%20TOGGLE
http://<ip>/cm?cmnd=Power%20On
http://<ip>/cm?cmnd=Power%20off
http://<ip>/cm?user=admin&password=joker&cmnd=Power%20Toggle

If you have set a password for web user interface access, this must be included (in plaintext) in the URL of the HTTP request, like so:

http://<ip>/cm?user=<username>&password=<password>&cmnd=Power%20On

in Console in the Web UI~

Console menu in the web UI is a convenient place to send commands and it behaves similar to a terminal connection via serial bridge.

over Serial Bridge~

If you flashed the device via serial method you can connect to it with a terminal application (e.g. Termite or Arduino IDE Serial Monitor) to issue commands and follow responses. This is a practical way to do a Backlog setup of your new device.

the Power of Backlog~

Backlog command allows executing up to 30 consecutive commands with a single command line. Each command is separated by a semicolon (";"). Backlog is a useful feature to avoid numerous restarts when setting up a new device. You can use it to:

Set up both Wi-Fi AP's

Backlog SSID1 <myssid>; Password1 <mypassword>; SSID2 <myssid2>; Password2 <mypassword2>

Configure MQTT broker address, MQTT credentials, device topic and activate a few custom options

Backlog MqttHost <yourhost>; MqttUser <user>; MqttPassword <password>; Topic <customtopic>; SetOption53 1; PowerRetain on

For specific power control, using backlog like a script

Backlog Status 1; Power2 on; Delay 20; Power2 off; Status 4

When using web requests (Don't forget to encode "space" as '%20' and ";" as '%3B')

http://<ip>/cm?user=admin&password=joker&cmnd=Backlog%20Power%20Toggle%3BPower1%20ff

A Backlog command without an argument clears an possible existing Backlog queue.

Serial Bridge~

Both hardware and software Serial Bridge are supported.

Hardware Serial Bridge uses GPIO1 (Tx) and GPIO3 (Rx) or GPIO13 (Tx) and GPIO15 (Rx) pins of your device.
Software Serial Bridge can use any other GPIO to be configured as components Serial Tx and Serial Rx (or SerBr Tx and SerBr Rx). If Tx and Rx components are not assigned in the Template or Module, GPIO1 and GPIO3 will be used. Note that changing serial logging (SerialLog 0) will disable the hardware Serial Bridge.

Information received by Tasmota over the serial bridge is captured automatically. Before data will be received, a properly formatted SerialSend<x> or SSerialSend<x> command must be executed. This must be done any time the device restarts (e.g., via a System#Boot triggered rule). This command is required in order to set how the expected serial data will be formatted and interpreted (i.e., which <x> option). A {"SSerialReceived":{"Data":"<string>"}} message will be posted. You can use a rule to process the string which will be contained in SSerialReceived#Data.

Expect possible communication errors when additional sensors are configured.

Command	Parameters
<device>	As <device> in following commands you can use interchangeably: <shortaddr> = short address of the Zigbee device on the network, example: 0x1234 <longaddr> = permanent IEEE address of the Zigbee device (64 bits), example: 0x00158D00041160C5 <index> = number of the device in the internal list (starts at 1), ideal for enumerating devices, example: 3 for third device in the list <name> = friendly name. Only when previously set with ZbName
ZbBind	Binds one Zigbee device to another device or to a group. This allows one device to directly send commands (f.e. a remote to a bulb) without any action on the coordinator. Command structure: {"Device":"<device>", "Endpoint":<endpoint>, "Cluster":<cluster>, "ToDevice":"<to_device>", "ToEndpoint":<to_endpoint>, "ToGroup":<to_group> } <device> = device sending messages (mandatory) <endpoint> = source endpoint (mandatory) <cluster> = source cluster id (mandatory) <to_device> = target device (optional) <to_endpoint> = target endpoint  (optional if it can be inferred from ZbStatus3) <to_group> = target group id (optional) You must specify either "ToDevice" or "ToGroup" but not both Zigbee2Tasmota must know the IEEE address of target device, see ZbStatus2 to verify and ZbProbe to have Zigbee2Tasmota query the address
ZbConfig	display the current Zigbee configuration Example or result: {"ZbConfig":{"Channel":11,"PanID":"0x1A63","ExtPanID":"0xCCCCCCCCCCCCCCCC","KeyL":"0x0F0D0B0907050301","KeyH":"0x0D0C0A0806040200"}}
ZbConfig <json>	change the configuration and restart if any change was applied. Warning: change in configuration causes a reset of the CC2530 and requires devices to be re-paired. "Channel":<channel>: Zigbee radio channel (11-26) "PanID":<panid>: identifier of the Zigbee Network "ExtPanID":<extpanid>: unique identifier of the Zigbee Network (ExtPanID features are not supported in Z2T but this parameter needs to be set) "KeyL":<key_l>,"KeyH":<key_h>: 128 bits encryption key, split into 2 64 bits values (Low and High) All parameters are optional and only the ones specified are changed. The command always displays the complete configuration after the change Example of command: ZbConfig {"Channel":22,"PanID":"0x1A69","ExtPanID":"0xDDCCCCCCCCCCCCCC","KeyL":"0xFF0D0B0907050301","KeyH":"0xED0C0A0806040200"}
ZbForget	Used for devices that are unused but still visible in ZbStatus <device> = Remove a device from the Tasmota flash memory.
ZbLight	Sets or reads the light type to be emulated in Zigbee Hue Emulation with Alexa. <device>,<light_type> sets the light type using an integer 0..5 corresponding to the number of channels (from one channel (on/off) to 5 channel (RGBCCT) lights) <device>,-1 removes the device from Philips Hue emulation <device> displays the current status of the Light (Zigbee2Tasmota tracks all changes to the light)
ZbName	Sets or reads the Zigbee device friendly name (up to 32 characters). <device>,<name> sets the new friendly name <device>, (empty name) clears the friendly name <device> displays the current friendly name Also see SetOption83 1 to enable friendly names as JSON keys instead of ShortAddr.
ZbPermitJoin	Sets pairing mode for new device discovery 0 = disable pairing mode 1 = enable pairing mode for 60 seconds 99 = enable pairing until device reboots Leaving Zigbee network open to join will allow any Zigbee device to connect and retrieve your network encryption key. This can lead to a compromise of your Zigbee network.
ZbPing	<device> = test availability of Zigbee device. If the device is connected and not sleeping, you should receive a ZbPing message within the next second. Example: ZbPing 0x5ADF responds with: {"ZbPing":{"Device":"0x5ADF","IEEEAddr":"0x90FD9FFFFE03B051"}}
ZbSend	Command structure: {"Device":"<shortaddr>", "Endpoint":"<endpoint>", "Manuf":<manuf>, "Send":{"<sendcmd>":<sendparam>}} <shortaddr> = short address of the Zigbee device on the network <endpoint> = target endpoint on the device (understanding endpoints) <manuf> = (optional) forces a specific ManufacturerId in the ZCL frame (required by some Xiaomi devices) "<sendcmd>":<sendparam> = command and parameters to send (Zigbee Device Commands) Use ZbZNPSend to send a raw form low-level message Example: ZbSend { "Device":"0x1234", "Endpoint":"0x03", "Send":{"Power":"on"} }
ZbStatus<x>	Display Zigbee devices seen on the network since boot <device> (optional) = all devices This command provides three levels of increasing detail according to <x> ZbStatus1 Display Short Address, and Friendly Name ZbStatus2 Also include Manufacturer ID and Model ID ZbStatus3 Also include a list of endpoints and the clusterIds supported by each endpoint Example: ZbStatus3 1 requests all details for device number 1 Requested information may exceed maximum result size allowed by Tasmota. In this case, the output will be truncated. To get all of the desired information, request results for a specific device individually.
ZbUnbind	Unbinds one Zigbee device from another or from a group. {"Device":"<device>", "Endpoint":<endpoint>, "Cluster":<cluster>, "ToDevice":"<to_device>", "ToEndpoint":<to_endpoint>, "ToGroup":<to_group> } <device> = the device sending the messages (mandatory) <endpoint> = the source endpoint (mandatory) <cluster> = the source cluster id (mandatory) <to_device> = the target device (optional) <to_endpoint> = the target endpoint (optional if it can be inferred from ZbStatus3) <to_group> = the target group id (optional) You must specify either "ToDevice" or "ToGroup" but not both Zigbee2Tasmota must know the IEEE address of the target device, use ZbStatus2 to verify and ZbProbe to query the address.

Zigbee Debug Functions

Do not use unless you know exactly what you are doing.

Command	Parameters
ZbModelId	Manually force the ModelId field of a Zigbee device. This is used to simulate devicesnot physically present on the network, for debugging only. <device>,<modelid> = set new ModelId <device>, = (empty modelid) clear ModelId <device> = display current ModelId (also displayed in ZbStatus2)
ZbProbe	<device>= probe a Zigbee device to get additional information including its IEEEaddress, vendor and model names, endpoints, and supported clusters per endpoint. Device probe is performed automatically when a new Zigbee device connects. Battery powered Zigbee devices can not be probed in general because they are usually in sleep mode.
ZbRead	Read Zigbee device attributes using command syntax: { "Device":"<shortaddr>", "Endpoint":"<endpoint>", "Cluster":"<cluster>", "Manuf":<manuf>, "Read":[<attrlist>] } <shortaddr> = short address of the Zigbee device on the network. <endpoint> = target endpoint on the device (understanding endpoints) <cluster> = cluster number of the attributes <manuf> = forces a specific ManufacturerId in the ZCL frame (required by some Xiaomi devices) (optional) <attrlist> = requested attributes array Example: ZbRead { "device":"0x69CF", "endpoint":"0x03", "cluster":"0x0006", "read":["0x0000"] }
ZbReset	1 = perform a factory reset and reconfiguration of the CC2530 chip. You will need to re-pair all Zigbee devices
ZbRestore	Restores a device configuration previously dumped with ZbStatus2. This command does not pair a device, but lets you get back device configuration like ModelId or IEEEAddress. <json> = json contains the fields dumped with ZbStatus2. <json> can contain multiple devices (if they fit).
ZbSave	Forces saving the Zigbee device information to Flash. Auto-saving happens 10 seconds after a new Device parameter was changed, this command is normally not useful
ZbZNPSend	Send a raw ZCL message to a Zigbee device. This is a low-level command, and requires to manually build the ZCL parameters. Most common usage will be provided as high-level functions.
ZbZNPReceive	Simulates a received message <hex> = hex string of the simulated message, same format as ZbZNPReceived debug logs
