Somfy blinds automated via MQTT and Home Assistant

I just replaced all my blinds with Somfy motors as well (project of last weekend).

My plan is to do something similar except I plan to use a small board with a small microcontroller (probably a STM8) to send the radio frames to the motor controllers.

It feels great to have a full home automation system that doesn't rely on any cloud technology. It's more secure and I'm sure that no product will lock me out of usage when they EOL.

For my own home automation setup I'm using a device called RFXCom. It plugs into a USB port and can send and receive all sorts of remote control signals, not just IR but also things like the Somfy protocol mentioned in the article.

It's really nice because to the hardware it just looks like a regular remote control. No soldering needed either.

I just had a lightning strike that destroyed a mid 1990s era somfy DSM controller. The cost to replace the entire system is 11K.

I havent done any experimentation, but are there any wireless replacement boxes that can activate the motors?

I tried this two times, but couldn't get it to work. I ended up going the Shelly switch route with Tasmota and much prefer the solution.
