Shutters and Blinds~

Control blinds and roller shades connected to regular ON/OFF motors,stepper motors or position servos

Before starting you have to enable shutter support with SetOption80 1

Commands~

Complete list of commands is available at Blinds, Shutters and Roller Shades Commands.

Shutter Modes~

There are five shutter modes which define how the relays operate. Additionally you can define PulseTime on any relay to change the relay into a pulse relay where the pulse changes start/stop. We recommend at least for Shutter mode 1 to define an Interlock setting.

The examples below are for a ShutterRelay1 1 configuration (using Relay1 and Relay2).

Shutter mode 1 - Normal Operation

First relay: OFF/DOWN, Second relay: OFF/UP

  • Interlock 1,2 (Interlocked relay pair)
  • Interlock ON

Shutter mode 2 - Circuit Safe

First relay: ON/OFF, Second relay: UP/DOWN

  • Interlock OFF

Shutter mode 3 - Garage Motors

First relay: OFF/DOWN PULSE, Second relay: OFF/UP PULSE

Shutter mode 4 - Stepper Motors

First relay: ON/OFF, Second relay: UP/DOWN

  • PWM: Stepper signal, COUNTER: Stepper position signal
  • PWM and COUNTER defined

Shutter mode 5 - Servo Motors (PWM position based servo)

First relay: ON/OFF, Second relay: UP/DOWN (optional not used)

  • PWM: Stepper signal
  • PWMfrequency 200 ( This is mandatory for most relay to get correct PWM duty cylces)
  • SetOption15 0 (required to store value and make it reboot save)

Wiring diagrams for Normal, Stepper motor, and Short Circuit-Safe configurations are available at the end of this page. Even if the shutter does not have two motors, three wires have to be connected.

Note

After setting the options for shutter mode, the device must be rebooted. Otherwise, the sliders won't be available in the web UI, and the ShutterOpenDuration<x>and ShutterCloseDuration<x> commands will report "Shutter unknown".

Operation~

Turning a device relay on or off directly (i.e., using Power) will function to affect a shutter's movement. In momentary mode (i.e., stepper motor), the relays start or stop the motor. The driver takes care of the direction and proper update of the shutter position.

The shutter reports its position and can also be sent to a dedicated position. ShutterPosition 0 means the shutter is closed and ShutterPosition 100 means the shutter is open. If you need the position values reversed (0 = open, 100 = closed), define and calibrate your shutter as documented below. Then tell Tasmota to reverse the shutter position meaning via the ShutterInvert<x> 1 command. All internal calculations are the same (the log output is the same). Only the interaction with the user and other systems changes. Now ShutterPosition<x> 0 will open the shutter and ShutterPosition<x> 100 will close the shutter.

By default, only Shutter1 is enabled when SetOption80 1 is invoked.
If possible to avoid any injury on unexpected movement all RELAYS should start in OFF mode when the device reboots: PowerOnState 0

A maximum of four shutters per device are supported.

To enable additional shutters, ShutterRelay<x> <value> must be executed for each additional shutter. Additional shutter declarations must be sequentially numbered, and without gaps (i.e., second shutter is 2, next shutter 3 and finally shutter 4).

Disabling a shutter in the middle of the defined set of shutters will disable all other higher numbered shutters. If the disabled shutter is restored, the higher numbered shutters previously declared will also be restored. When a shutter is added or removed, a list of the active shutters, with their parameters, is output to the log. If you intend to remove shutters, explicitly remove each one beginning with the highest numbered shutter.

With four shutters, eight Relay<x> components are needed. If manual operation switches (Switch<x> or Button<x> pairs) are also used, additional input GPIO are required. The ESP82xx device may not have enough free GPIO to support all the shutter connections required. A GPIO expander such as a PCF8574 or MCP230xx can be used with additional effort.

Using manual operation Switch<x> pairs may require setting SwitchMode<x> 4 (inverse follow) for proper switch behavior.

Any shutter positioning can be locked ShutterLock<x> 1. Once executed an ongoing movement is finished while further positioning commands like ShutterOpen<x>, ShutterClose<x>, ShutterStop<x>, ShutterPosition<x>, ... as well as web UI buttons, web UI sliders, and shutter buttons are disabled. This can be used to lock an outdoor blind in case of high wind or rain. You may also disable shutter positioning games by your children. Shutter positioning can be unlocked using ShutterLock<x> 0. Please be aware that the shutter can still be moved by direct relay control (i.e., Power<x>), or physical switches and buttons. Use the ShutterButton<x> command prior to ShutterLock to be able to lock buttons.

Calibration~

Shutter calibration video tutorial

Shutter calibration Google Spreadsheet

  • Start your shutter in a closed position preferably. Set internal position to closed with ShutterSetClose<x>.
  • Set the time needed to open the shutter completely with ShutterOpenDuration<x>.
  • If the shutter opens more than needed, move it to the desired position with ShutterSetPosition<x> then set the position to fully open (100) with ShutterSetOpen<x> and decrease the open time.
  • Set the time needed to close the shutters with ShutterCloseDuration<x>.
  • If the shutter does not close completely, open again and adjust close time.
  • If it runs too long, move it back to desired closed position with ShutterSetPosition<x>, reset to 0 with ShutterSetClose<x> and decrease open time.
  • Alternate between opening and closing the shutter until you find out the exact times needed to get the same positions multiple times
  • Now set the 50% open position of the shutter. Some shutters need some time from totally closed until they begin moving the bottom-most part and opening. This often results in a shutter that is less than 50% open when the shutter has been operating for 50% of the set time. This can be corrected by using ShutterSetHalfway<x>. Use this procedure to calibrate the half-open position:
  • ShutterClose<x> (confirm that the shutter is completely closed)
  • ShutterSetHalfway<x> 50 (reset to default)
  • Move the shutter to actual 50% open position.
  • Use ShutterPosition<x> to inquire the shutter's current position and record the value. This value is a percentage of the total opening (e.g., 63 = 63% of opening).
  • ShutterClose<x>
  • ShutterSetHalfway<x> 63 (using the value from step #4 above)
  • Restart 1

After calibration is complete, you might want to enable an additional 1 second motor movement with ShutterEnableEndStopTime<x> 1 when the shutter is asked to move to its end positions (0% and 100%). With this you can guarantee that end positions are still reached in case of inaccuracies. Take care to disable this with ShutterEnableEndStopTime<x> 0 before further open or close duration measurements.

Increasing Calibration Granularity~

If you desire that the %-opening closely match what ShutterPosition<x> and web UI indicate, there is a granular calibration matrix available. Ensure that ShutterClose<x> and ShutterOpen<x> moves the shutter more or less to the limit positions and follow this procedure:

  • ShutterSetHalfway<x> 50 (reset to default)
  • ShutterCalibration<x> 30 50 70 90 100
  • Restart 1
  • ShutterClose<x>
  • Move the shutter to each of the following opening percentages and measure the shutter's position for each.
  • ShutterPosition<x> 30 (e.g., measurement = 15)
  • ShutterPosition<x> 50 (e.g., measurement = 50)
  • ShutterPosition<x> 70 (e.g., measurement = 100)
  • ShutterPosition<x> 90 (e.g., measurement = 150)
  • ShutterPosition<x> 100 (e.g., measurement = 180)
  • Finally, enter the position measurements as the calibration values: ShutterCalibration<x> 15 50 100 150 180

ShutterCalibration<x> takes position measurements (not the time it takes to move). During calibration you position the shutter to an indicated percentage (e.g., 30%) of opening and measure the shutter position (e.g., 15). Use the same unit of measure for all your measurements (e.g., centimeters, inches, steps, etc.). After calibration ShutterPosition<x> 30 will move to 30% opening. This will be 30% from 180 (full open) == 54. Now the percentage match the percent in cm/inch/steps.

Notice that there is no calibration for the 10% position. On many shutters, there is no movement during the initial phase (i.e., nearly 10% of total time). Therefore the opening could be 0. This measurement would cause an execution DIV 0 exception. Therefore the first calibration point is 30%. In most cases this is not a large opening so the calibration will be near enough. Yes, until ~10%, the position will be a bit "off" but not enough for concern.

Motor Movement Delays~

Some motors need up to one second after power is turned on before they start moving. You can confirm if you are having this issue if opening and closing as a single action works properly but doing this in smaller steps result in a shift of the position.

  1. Shutterposition<x> 30
    Measure the shutter position. This is the reference_position
  2. Shutterposition<x> 80
    Measure the shutter position. This is the max_position
  3. Shutterposition<x> 30
    Return the shutter to starting position. This must be the same position as measured in step #1 (reference_position). If not, ShutterCloseDuration must be adjusted.
  4. Shutterposition<x> 50
  5. Shutterposition<x> 70
  6. Shutterposition<x> 80
    If you do not reach max_position you have a motor delay problem. Measure the shutter position. This is the real_max. Use this value in the calculation below.
  7. ShutterMotorDelay<x> <delay>
    Motor <delay> calculation - fine tune in 0.05 second increments (e.g. 0.65) as required.
    <delay> = ((max_position-real_max) / 2) / (((100/80) * max_position) / ShutterOpenDuration)

Close the shutter and repeat this procedure until the motor delay is set properly.

Button Control~

When shutter is running in default ShutterMode 0, you already have basic control over the shutter movement using switches or buttons in the module configuration to directly drive the shutter relays. For short circuit safe operation ShutterMode 1 direct control of the relays will not give you a nice user interface since you have to 1st set the direction with one switch or button and 2nd switch on the power by the other switch or button.

To have shutter mode independent button control over the shutter and not over its relays one can use the ShutterButton<x> command. It also introduces some more features, see below:

ShutterButton<x> <button> <func> <mqtt>

This assigns a Tasmota button <button> to control your shutter <x> having functionality <func>. The Tasmota button <button> must already be configured in the module configuration. You can assign multiple buttons to a single shutter. Any button can only control one shutter (beside the <mqtt> broadcast feature, see description below). Any press of the button while the shutter is moving will immediately stop the shutter.

One can remove all button control for shutter <x> by ShutterButton<x> 0.

The assigned button can have one of the following functionalities:

  • Setup for an "up" button: ShutterButton<x> <button> up <mqtt>
    Single press will move shutter to 100%, double press to 50% and tripple press to 74%. Holding the button for more than the hold time (SetOption32) moves all shutters with same <grouptopic> to 100% when <mqtt> is equal to 1. When <mqtt> is equal to 0 hold action of this button is same as single press.

  • Setup for a "down" button: ShutterButton<x> <button> down <mqtt>
    Single press will move shutter to 0%, double press to 50% and triple press to 24%. Holding the button for more than the hold time (SetOption32) moves all shutters with same <grouptopic> to 0% when <mqtt> is equal to 1. When <mqtt> is equal to 0 hold action of this button is same as single press.

  • Setup for an "updown" button: ShutterButton<x> <button> updown <mqtt>
    Single press will move shutter to 100%, double press down to 0% and triple press to 50%. No hold action and no other shutter control by MQTT, <mqtt> is don't care here.

  • Setup for an "toggle" button: ShutterButton<x> <button> toggle <mqtt>
    Single press will toggle shutter, double press will move it to 50%. Be aware that the toggle select direction based on the current position. If the position is between 0..50% the shutter move to 100%. If the position is 51%..100% it moves to 0%. No hold action and no other shutter control by MQTT, <mqtt> is don't care here.

More advanced control of the button press actions is given by the following ShutterButton<x> command syntax:

ShutterButton<x> <button> <p1> <p2> <p3> <ph> <m1> <m2> <m3> <mh> <mi>

<button> 1..4: Button number, 0/-: disable buttons for this shutter
<p1> 0..100: single press position, t: toggle, -: disable
<p2> 0..100: double press position, t: toggle, -: disable
<p3> 0..100: tripple press position, t: toggle, -: disable
<ph> 0..100: hold press position, t: toggle, -: disable
<m1> 1: enable single press position MQTT broadcast, 0/-: disable
<m2> 1: enable double press position MQTT broadcast, 0/-: disable
<m3> 1: enable tripple press position MQTT broadcast, 0/-: disable
<mh> 1: enable hold press position MQTT broadcast, 0/-: disable
<mi> 1: enable MQTT broadcast to all shutter indices, 0/-: disable

Parameters are optional. When missing, all subsequent parameters are set to disable.

By a button single press the shutter is set to position <p1>. Double press will drive the shutter to position <p2> and triple press to position <p3>. Holding the button for more than the SetOption32 time sets the shutter position to <ph>. Any button action <p1> to <ph> can be disabled by setting the parameter to -. Independent from configuration <p1> to <ph> any press of the button while the shutter is moving will immediately stop the shutter.

Global steering of all your shutters at home is supported by additional MQTT broadcast. By any button action a corresponding MQTT command can be initiated to the <grouptopic> of the device. For single press this can be enabled by <m1> equal to 1, disabling is indicated by -. Double to hold MQTT configurations are given by <m2> to <mh>, correspondingly. When <mi> is equal to - only cmnd/<grouptopic>/Shutterposition<x> <p1..h> is fired. When <mi> is equal to 1, <x>=1..4 is used to control any shutter number of a Tasmota device having same <grouptopic>.

Example

  • ShutterButton<x> <button> 100 50 74 100 0 0 0 1 1 is same as ShutterButton<x> <button> up 1.
  • ShutterButton<x> <button> 0 50 24 0 0 0 0 1 1 is same as ShutterButton<x> <button> down 1.
  • ShutterButton<x> <button> 100 0 50 - 0 0 0 0 0 is same as ShutterButton<x> <button> updown 0.
  • ShutterButton<x> <button> t 50 - - 0 0 0 0 0 is same as ShutterButton<x> <button> toggle 0.

Module WiFi setup, restart, upgrade and reset according to Buttons and Switches are supported "child and fool proof" only when no button restriction (SetOption1) is given and when all configured shutter buttons of that shutter are pressed 5x, 6x, 7x times or hold long simultaneously.

Remote Control~

Use any other Tasmota device with buttons or switches to control remotely a shutter using rules. Similar behavior as direct button control can be achieved by applying ShutterStopClose, ShutterStopOpen, ShutterStopToggle, ShutterStopPosition commands. They stop shutter movement if it is in motion and otherwise execute close, open, toggle or position commands.

Example

Run this rule on another Tasmota device with a switch configured. rule1 on switch1#state=2 do publish cmnd/%shutter-topic%/ShutterStopToggle endon

Specific Configuration~

Note

The PWM remains on even after the end position has been reached. The motor then permanently tries to hold the position and could thereby trigger noises or a slight "twitching". If this is not desired, you can switch off the PWM after reaching the end position with #define SHUTTER_CLEAR_PWM_ONSTOP.

Pulse Motors~

There are shutters that have two relays but only need a pulse to start or stop. Depending on the current situation a pulse will stop the shutter or send it into a specific direction. To use these kinds of shutters a PulseTime must be defined on each relay. The minimum setting that seems to make it work consistently is 2. A setting of 1 does not work. If the shutter moves too fast and does not react to a stop command, increase the setting to 3 or 4.

Stepper Motors~

Stepper motors can also be used to operate shutters and blinds. Additionally you can operate sliding doors with this configuration.

Servo Motors~

Servos are small devices with typical 180° or 360" rotation movement. The position will be drived by the PWM duty cycle time. This will all automatically calculated

Note

If you miss low angles (i.e 2°) you should be able to get this by changing the minimum ShutterPWMRange. If this does not help you can customize PwmFrequency. Normally for PWM servos, there is no calibration required, but you have the option to do a calibration. Check the documentation for shuttercallibration. Maybe ShutterSetHalfway is already enough. Otherwise you can do a fine granular calibration.

Note

If you change the shutteropenduration/closeduration the servo will operate slower, but now the servo also achieves small angle changes.

Servos and Steppers also have a velocity control. With ShutterMotorDelay<x> 1.5 you can define a 1.5second soft start/stop before the device reaches it final moving speed. Usefull for moving heavy items like doors.

using Stepper Motors~

Stepper motors can be used to operate shutters and blinds. The configuration is very similar to the Circuit Safe (Shuttermode 1) configuration. To operate a stepper motor requires driver module such as the A4988 and uses EN (enable), DIR (direction), STP (Stepper) for controls. If everything is defined correctly Shuttermode 4 will be reported at boot time.

Tasmota supports a maximum of four shutters with one stepper motor per shutter simultaneously. In very rare conditions where two or more shutters simultaneously move the last mm it can happen than one shutter moves to far.

Example configuration~

EN and DIR are on Relay1i and Relay2 respectively. Please be aware to use the inverse relay for the enable signal.

The STP signal is assigned as a PWM<x> component where <x> matches the number of the shutter (e.g., PWM1 for Shutter1). The shutter feature adjusts the PWM frequency to operate the motor for proper shutter operation. The stepper motor frequency setting is a global setting all PWM components on the device. This means that all shutters on the device will operate at the same speed. Therefore no PWM devices other than shutters can be connected to the same Tasmota device.

The frequency of the PWM can be changed from 1000Hz to any value up to 10,000Hz. The command ShutterFrequency globally changes this. Be aware that most 12V operated motors cannot work faster than 2,000Hz. 5,000Hz.10,000Hz is possible by increasing the supplied voltage to 24V and use ShutterMotorDelay to allow a slow speed up/speed down. The maximum voltage of the A4988 is 36V. The TMC2208 is much more silent than the others but also significant slower and does not like high frequencies. For example, the speed at 24V is half o A4988

Finally a GPIO must be assigned as Counter1. This counter is used to keep track of the steps and send the stepper to the correct position. The Counter1 GPIO must be connected to the PWM1 GPIO. Otherwise the stepper and your shutter will run continually or freeze up randomly.

Only bipolar stepper motors may be used (see above).

You must properly configure the stepper motor driver (see above).

ShutterOpenDuration and ShutterCloseDuration can be different. Shutter with Stepper motors always match positions exact. There is no need to vary ShutterOpenDuration and ShutterCloseDuration. Anyhow, if you decrease ShutterCloseDuration the Shutter will close with a higher speed on a virtual higher ShutterFrequency if possible. Same vice versa.

You can define a soft start/stop by defining a ShutterMotorDelay. This causes the driver to ramp the speed up and down during the defined duration. The change of the ShutterMotorDelay does NOT change the distance the shutter makes. This is very convenient to trim the accelerate and decelerate rate without changing the distance.

Bill of Materials~

using Sonoff Dual R2~

If using a Sonoff Dual R2, use the following Template:

{"NAME":"Sonoff Dual R2","GPIO":[17,255,0,255,0,22,18,0,21,56,0,0,0],"FLAG":0,"BASE":39}

Checklist~

  • Ensure that the first relay opens the shutter
  • Ensure that the second relay closes the shutter
  • Set ShutterRelay<x>
  • Set ShutterOpenDuration<x>
  • Set ShutterCloseDuration<x>
  • Set ShutterSetHalfway<x> (optional)
  • Set ShutterInvert<x>(optional)
  • Set ShutterInvertWebButtons<x>(optional) (eg. useful for horizontal awnings)
  • If the shutter uses a pulse motor instead of a motors with one wire for each direction (i.e., duration based), define PulseTime<x> 2 on both relays. The driver's behavior will change to a pulse motor that needs pulses to start and stop.

Rules~

Tasmota rule triggers:

  • Shutter<x>#Position is triggered at start, during and at the end of movement reporting actual position (%value%=0-100)
  • Shutter<x>#Direction is triggered at start, during and at the end of movement reporting actual direction (%value%: -1=close direction, 0=no movement, 1=open direction)
  • Shutter<x>#Target is triggered at start, during and at the end of movement reporting current target (%value%0-100)
  • Shutter#Moving is triggered during movement and just before moving (shutter independently). If VAR<x> is set to 99 then this trigger will be executed BEFORE the shutter starts. You can start the shutter after rule execution by setting VAR<x> to 0 or wait 10seconds before the timeout kicks in. After the movement with shutter#moved the VAR must be set back to 99 and the initial rule must be enabled again. The initial rule has to be defined to run ONCE. EXAMPLE: power3 on and wait 2sec before start. After movement: power off
    rule1 on shutter#moving=1 do backlog power3 on;delay 20;var1 0 endon
    rule1 5
    rule2 on shutter#moved do backlog power3 off;var1 99;rule1 5 endon
    rule2 1
    
  • Shutter#Moved is triggered at end of movement (shutter independently)
  • Shutter<x>#Button<button>=0 is triggered when button is hold
  • Shutter<x>#Button<button>=<n> is triggered when button is pressed n times
  • Shutter<x>#Button0=0 is triggered when all buttons of that shutter are hold simultaneously
  • Shutter<x>#Button0=<n> is triggered when all buttons of that shutter are pressed simultaneously n times

Examples

  • Publish a message with the position of the shutter: Rule1 ON Shutter1#Position DO Publish status/%topic%/level {"%value%"} ENDON
  • Open/Close or set a specific position for a shutter. This example drives the second shutter to the same position as the first shutter:
    Rule1 ON Shutter1#Position DO ShutterPosition2 %value%" ENDON

Jarolift Shutter Support~

Jarolift shutters operates by the 3 commands up/stop/down. Compile with the KeeLoq Option and provide the extracted master keys to communicate. Please see KeeLoq description how to do that. After this create a rule to allow the shutter to control the Jarolift devices. Shutter must be in ShutterMode 0.

Rule1 On Power1#state=0 DO KeeloqSendButton 4 endon On Power2#state=0 DO KeeloqSendButton 4 endon on Power1#state=1 DO KeeloqSendButton 8 endon on Power2#State=1 DO KeeloqSendButton 2 endon

Venetian Blind Support~

All time based shutters (not stepper, pwm) can be enhanced with Venetian Blind functionality. The configuration need following parameters: angle of blinds during OPEN, angle of blinds during CLOSE. This are the max and the min values of the venetian blinds (e.g. -90° to 90°). Additionally the runtime is required from min to max and reverse. This is typically 1-2sec. The resolution of the time is 0.05sec. Duration in [sec] must be multiplied by 20. e.g. 1.2sec => 1.2 x 20 = 24. Two open and close the tilt you can define the angle for OPEN and the angle for CLOSE of the tilt. shuttertiltconfig1 -90 90 24 0 -90

Tilt configuration can be set for every shutter independently. The tilt can be set with one of the following commands: shuttertilt1 open set tilt to defined open angle shuttertilt1 close set tilt to defined close angle shuttertilt1 20 set tilt to 20° angle

If the shutter is moved from one position to another position the tilt will be restored AFTER the movement. If the shutter is fully opened or fully closed the tilt will be resetted. This means there is no tilt restore at the endpoints.

Similar to shutterchange to make relative movements there is also a shuttertiltchange with the same behavior.

If the shutter is operated with wall buttons or the web interface and stopped during a tilte change before the shutter starts moving the NEW tilt position is stored. Now any additional position movements will restore this new tilt position. This makes is possible with small ON/OFF to change the tilt and with long ON/OFF to change the position and retain the tilt after movement.

Similar to shutterposition there is a minimum runtime of the motor required that TASMOTA can control. This is 0.2sec. Because the tiltmovement from one position into the other takes often about 1sec it is very common that you cannot make small tilt changes of 10° or sometimes even 20".
