Make Your Ceiling Fans Smart with Home Assistant - Round 2

Oh right, remote_receiver doesn't allow setting the frequency to 350MHz... this is paving new road from anything I've done then.

From the #6300 PR, maybe it is still possible to receive at 350MHz by doing

cc1101:
  id: transceiver
  cs_pin: GPIO5
  output_power: 11
  tuner:
    frequency: 350000
  ...

and then:

remote_receiver:
  pin: GPIO33  # GDO2
  dump:
    - raw
  tolerance: 50%
  buffer_size: 2kb
  filter: 250us
  idle: 10ms

Victor Chang Hey Victor, thanks so much for getting back to me. Your suggestions are actually exactly what I did. I downgraded to 2024.12.2 and was able set it up so i can receive my 350MHz signals. I'm now at the point where I'm trying to make transmitting the signals back to the fan work. It's odd that your Flipper Zero captured a much longer 350MHz signal than mine. The raw output I captured is shorter than yours and I haven't even tried to trim it yet. So far, transmitting that signal doesn't seem to work.

If I use your code on the latest ESPhome, I get an error that 350000 isn't supported in the ESPhome logs when pressing the button. If I go back to 2024.12.2 I no longer get that error but the fan isn't responding.

Bottom line is I'm still going back and forth on it but feel like I'm close. Any other tips you've got would be greatly appreciated!

Hey Matt, did you manage to solve this in the end? I'm having an almost identical problem. Has anything changed in the last 8 months? Cheers!
