Remote Receiver Component

The remote_receiver component lets you receive and decode any remote signal, these can for example be infrared remotes or 433MHz signals.

The component is split up into two parts: the remote receiver hub which can be used to receive, decode and dump all remote codes, and individual remote receiver binary sensors which will trigger when they hear their own configured signal.

# Example configuration entry
  pin: GPIO32
  dump: all

Configuration variables:

  • pin (Required, Pin): The pin to receive the remote signal on.
  • dump (Optional, list): Decode and dump these remote codes in the logs. Set to all to dump all available codecs:
    • lg: Decode and dump LG infrared codes.
    • nec: Decode and dump NEC infrared codes.
    • panasonic: Decode and dump Panasonic infrared codes.
    • samsung: Decode and dump Samsung infrared codes.
    • sony: Decode and dump Sony infrared codes.
    • rc_switch: Decode and dump RCSwitch RF codes.
    • raw: Print all remote codes in their raw form. Useful for using arbitrary protocols.
  • tolerance (Optional, int): The percentage that the remote signal lengths can deviate in the decoding process. Defaults to 25%.
  • buffer_size (Optional, int): The size of the internal buffer for storing the remote codes. Defaults to 10kb on the ESP32 and 1kb on the ESP8266.
  • filter (Optional, time): Filter any pulses that are shorter than this. Useful for removing glitches from noisy signals. Defaults to 10us.
  • idle (Optional, time): The amount of time that a signal should remain stable (i.e. not change) for it to be considered complete. Defaults to 10ms.
  • id (Optional, ID): Manually specify the ID used for code generation. Use this if you have multiple remote transmitters.
