Esphome Aqara Curtain Motor (ZNCLDJ11LM)

Converts Aqara Zigbee Motor ZNCLDJ11LM to Esphome

I was having zigbee range issues in my home due to a tiny number of devices in my mesh (just two motors). I had improved range when adding in smart plugs (used as routers), but ultimately I came back to my mantra of avoiding wireless devices.

I am currently using a Wireless-Tag WT32-ETH01 to add my motor to my network via ethernet. However, my WiFi setup is very good, so I will likely switch to Wemos Mini D1 as I have other plans for the "more-expensive" WT32-ETH01.

Setup

Add the uart_curtain.h file to a directory where esphome can access it.

See my yaml file for an example config.

Todo Improvements:

• Check for "confirmation" (and ask again if failed?)
• Better error checking states
• One button calibrate (full open-close cycle)
• Consistent code-style (sorry)
• Look into avoiding "custom" components - as per https://gitlab.com/ripnetuk-public/esphome/ripnetuk-esphome-easynow
