Motorized_MQTT_Blinds

I forked to add a couple of other base sizes. This is a great project to get the idea of how things work, but the contollers weren't staying connected with my HomeAssistant instance. I ultimately use the hardware from this repo with Tasmota configured in Cover mode instead. The instructions look daunting, but it takes longer to read than to set up, and it's been running rock solid for months now...

Make sure you use 2208's for noise control, otherwise you can have a rude awakening!

3D Printing

Download the correct STL file for your style of tilt rod

Wiring Schematic

Dont forget to cut the center trace on the stepper motor as shown in the youtube video

File setup

Fill out the entire USER CONFIGURATION section of the code.

You should leave "STEPS_TO_CLOSE" at 12 to start with. It can be adjusted for your specific blinds

Home Assistant YAML

Replace "BlindsMCU" with your MQTT_CLIENT_ID if you changed it in the file setup

Home Assistant 2022.7.5 and Later:

mqtt:
  cover:
    - name: "BlindsKitchen"
      command_topic: "BlindsMCU/blindsCommand"
      position_topic: "BlindsMCU/positionState"
      set_position_topic: "BlindsMCU/positionCommand"
      retain: true
      payload_open: "OPEN"
      payload_close: "CLOSE"
      payload_stop: "STOP"
      position_open: 0
      position_closed: 12

Home Assistant 2022.6.5 and Earlier:

cover:
  - platform: mqtt
    name: "Motorized Blinds"
    command_topic: "BlindsMCU/blindsCommand"
    set_position_topic: "BlindsMCU/positionCommand"
    position_topic: "BlindsMCU/positionState"
    retain: true
    payload_open: "OPEN"
    payload_close: "CLOSE"
    payload_stop: "STOP"
    position_open: 0
    position_closed: 12
