Sonoff R2 RF Pin Configuration remote_receiver

ESPHome

Hi All,
I have a Sonoff RF Switch with 433 MHz, not the RF Bridge, with which I want to receive a 433 MHz Switch Signal. ()

The tutorial on Tasmota site has some remarks - Sonoff RF - Tasmota - is this required for esphome as well? The tasmota pin mapping does not concretely state which pin to use Tasmota/tasmota_template.h at 900269ad446e017f706ddaff5c5efbf285adcbeb · arendst/Tasmota · GitHub

I configured the esphome device accordingly and it does not recognize any 433 mhz signal.

So which Pin should be used?

remote_receiver:
  pin: GPIO3
  dump: all
  # Settings to optimize recognition of RF devices
  tolerance: 50%
  filter: 250us
  idle: 4ms
  buffer_size: 2kb

It states a warning for the “high” pin.

Anyone already figured this out?

Did you try with inverted: true?

remote_receiver:
  pin: GPIO3
  dump: all
  # Settings to optimize recognition of RF devices
  tolerance: 50%
  filter: 250us
  idle: 4ms
  buffer_size: 2kb
  inverted: true  #  <--- like this

Tried inverted: true in the pin configuration - with still no suitable results.

remote_receiver:
  pin: 
    number: GPIO3
    inverted: true
  dump: all
  # Settings to optimize recognition of RF devices
  tolerance: 50%
  filter: 250us
  idle: 4ms
  buffer_size: 2kb

The log output does not provide any receiving information - is GPIO03 correct?

you will not be able to manage 433 MHz from esphome. follow the instructions on the link for tasmota
