RTL_433 Decoder Component for ESPHome

This ESPHome external component provides rtl_433 decoders for ESPHome remote_receivers.

Basic how-to:

1. Include what is needed for this external component via packages directive in your esphome yaml config:

   packages: 
       rtl_433: github://juanboro/esphome-rtl_433-decoder/rtl_433.yaml

2. Add the rtl_433 config to your yaml with a remote_reciver id and an on_json_message handler...

   rtl_433:
       id: my_rtl433_id
       receiver_id: rf_receiver
       on_json_message: 
           then:
               ....

   You can find example ESPHome json message trigger handling examples in the ESPhome MQTT documentation. Examples are also included here.

3. (optional) Alternatively to setting receier_id, you can send raw OOK/FSK pulse data to the decoder via lambdas like this:

       - lambda: |-
           id(my_rtl433_id).recv_raw(rawdata);

Working Examples

Two examples are provided:

1. esp32-rtl_433-decoder.yaml - MQTT relay - generates rtl_433 style MQTT messages from decoded receiver data. Also includes example of how to generate Home Assistant API events.
2. esp32-rtl_433-sensors.yaml) - Example of creating specific ESPHome sensors from rtl_433 json messages. It also shows how to limit to the component to only specific protocols, which will speed up processing and help prevent: Component remote_receiver took a long time for an operation (>30ms)

The example configurations points to a configuration with a ESP32 dev board connected to a TI-CC1101 board (both from AliExpress ~ $5 total). However, any working way of receiving OOK on/off pulses or FSK mark/space data should be able to work.
