LoRa32 433MHz

Bridges Athena to a LilyGo LoRa32 433MHz board - a bare ESP32+LoRa dev board with no vendor API of its own - running OpenMQTTGateway, the de facto standard firmware for it, over MQTT rather than a local HTTP/BLE connection.

How it works

Received 433MHz RF codes arrive on the gateway's own 433toMQTT topic; sending a code publishes to its commands/MQTTto433 topic - confirmed against OpenMQTTGateway's own current documentation. RF codes are entirely user-defined, the same pattern KNX uses for its own datapoints (there's no discovery protocol for arbitrary 433MHz remotes/sensors) - each one you define shows up as a button entity under the gateway, and pushes live to Athena with no reconnect needed.

Works with Dashboard cards and Automations exactly like every other integration.
