A demo of how the rtl_433_ESP library can be used with ESPHome.

I'm using the 433 Mhz version of the LoRa32 V2.1_1.6.

external_components:
  - source: github://mag1024/esphome-rtl433

rtl433_mqtt:
  id: gateway
  mqtt_id: my_mqtt

# improves OTA stability
ota:
  on_begin:  
    - rtl433_mqtt.stop: gateway

Configuration variables:

• mqtt_id (Required): id of a configured MQTT Client component.
• topic_prefix (Optional): Defaults to rtl_433
• source (Optional): A value for the source= field added to the published JSON. Useful if you have multiple boards publishing to the same topic.
