Have been working on this for a bit - somewhat timely that HA is going to support RF in 2025.5 so this may no longer be required or can eventually be baked into HA.
All of the solutions I have tried for controlling a Proflame 2 remote for my fireplace have been half baked at best. This works very well. I have tested on both a lilygo esp32 device with an embedded cc1101 and an esp32 dev board wired up to a cc1101 module.
Pairing your existing remote can be done on-device (lilygo) or through home assistant. No external SDR or any other hardware required. Flash from web, pair your remote and be up and running in less than 5 minutes, or build your own YAML for more customization.
Please post any feedback / bugs / feature requests on github.
Please read the documentation when setting your device up.
