ESPHome on Sonoff RFBridge

ESPHome
1

I’ve installed ESPHome on an RFBridge (I have another one in production with tasmota, but want to swap).
When I look in the log, I see this warning:

[17:55:14][C][remote_receiver.esp8266:060]:   Pin: GPIO4 (Mode: INPUT)
[17:55:14][W][remote_receiver.esp8266:063]: Remote Receiver Signal starts with a HIGH value. Usually this means you have to invert the signal using 'inverted: True' in the pin schema!
[17:55:14][C][remote_receiver.esp8266:065]:   Buffer Size: 1000

My config looks like this:

So should I add the inverted: yes for receiver?

Yes, that’s what the warning message suggested that you should add the inverted

remote_receiver:
 pin: 4
 dump: rc_switch
 tolerance: 50
 filter: 4us
 idle: 4ms
 inverted: True

Hmm yes, I thought so too, but if I do that, I get this error:

I tried placing the ‘inverted’ statement directly under the pin, and also indent it, but I still get errors.

Not sure why log suggested that, but according to the source at https://esphome.io/components/remote_transmitter.html#remote-setting-up-rf

“inverted” should be place under protocol:

EDIT: Found a tutorial by Dr.Zzs for Sonoff RF, but he use ESPeasy, worth checking out tho. http://drzzs.com/sonoff-rf-bridge/

It should look like this:

Ahh, ok, got it.
Though I still get:
[21:36:14][W][remote_receiver.esp8266:063]: Remote Receiver Signal starts with a HIGH value. Usually this means you have to invert the signal using 'inverted: True' in the pin schema!

I removed the inverted: true again, as all my door sensor went silent with that set.
Weird. I don’t know much about the 433 MHz protocol, so I havce no idea why.
