Hello @magnayn ,

Did you get any further with this project? It looks like you got it working - even if "not 100% reliable" - well done and thank you for making it public.

I have an Elica hood and no remote. I run a RFLink for simple 433 and a Devmel AirSend for rolling code 433 both from a Home Assistant instance.

I'm looking at replicating your success - even if it was only partial.

If I was to go the ESP8266 way, can you tell me how you wired up your STX882? Like this?

Even better, do you know what protocol or modulation the Elica hoods use, perhaps I could find something compatible in RFLink or Devmel AirSend. Thanks in advance

I haven't actually put it in production anywhere - but yes, it all works in principle - I had it doing on/off.

I can't actually remember the setup I used. I think from memory you can pick any pin you like, just adjust uint8_t pin = 12;

If it's the same unit, it might "just work". If not, I can recommend getting a cheap saleae logic clone and attach it to a 433Mhz receiver. That's where you can retrieve the pattern the unit actually uses and adjust the code if necessary.

I just bit-banged the output - it looks like it's manchester encoded, but I don't recall it being at any particularly useful baud rate to use a UART.
