ESP home is so powerful like this. And is great to build components for (although I find this part a little complex, lots of Claude help…).

I’ve got a vibe coded “Nuaire Fan” controller to talk UART to my whole home ventilation and present it as a HA controllable fan.

Indeed! I have a CC1101 hooked up to an ESP32C6 that controls my Itho mechanical ventilation unit as a fan in HA.

I couldn't believe it when it basically worked on the first try, including pairing with the base unit and other remotes.
