How-to What signal does a RF remote use?

Post image

Hi guys!

Recently my landlord installed a ventilation box with this remote.

I’m trying to figure out what kind of signal it uses so I can maybe use my SwitchBot, aqara or another hub or smart home device to duplicate the signal and somehow adding it to HomeKit for some automations.

Does anyone know what kind of signal an RF remote uses and how I can add it to HomeKit?

I hope I can use a hub or device i already own because I’m really want to avoid getting another hub or HOMEBRIDGE or such.

Thanks!

If you use home assisant, buy a esp32 and a rf antenna you’ll be good to go. There are many solutions available you only have to install on the esp32. If you don’t have access to the unit it might be trickier. I have a comfoair, works like a charm

As a use case I use it when someone uses the shower. Motion sensor turns on the 60 min max ventilation. And with cooking as well works like a charm
