433MHz remote_receiver
#1
Hello,

I am using ESPHome 2024.5.5 on the KC868-A8S device. After uploading the firmware that includes the remote_receiver component on GPIO16 for 433 MHz receiving module, the device becomes unresponsive and the web dashboard returns ERR_CONNECTION_REFUSED. Interestingly, when the remote_receiver component is not included, everything functions as expected.

Any ideas about that? Thank you!

  board: esp32dev

you can test with this yaml whether work well.

Your YAML worked, thank you! I've tried to pinpoint what caused the error. It seems that using both remote_receiver and RGB light element does not work well together. I can use remote_receiver or WS2812B.

This is current working configuration:
