I would like to configure Home Assistant so that the ‘Mighty Mule FM231 Wireless Driveway Alarm’ is recognized as a binary sensor via RTL_433 to MQTT. The FM231 is a coil sensor, located by the driveway, that generates AM modulated RF signals at 433.92Mhz to a corresponding receiver, located in the home, that generates a sound.
-
The FM231 is installed, and the receiver sounds an alarm when a car disturbs the magnetic field around the coil sensor.
-
Mosquitto Broker integration is installed and communicating to a LILYGO® LoRa32 V2.1_1.6.1 433 Mhz board flashed with OpenMQTT Gateway v7.0 with Auto Discovery enabled.
-
Multiple AcuRite RTL_433 Indoor Outdoor Temperature and Humidity Sensors (592TXR) were discovered and configured as devices in HA
-
The FM231 is not discovered by HA and I’m unable to identify its topic in MQTT Explorer.
This old newb found Add support for mightymule driveway alarm FM231 (which references MightyMule-FM231.conf ) and assumed it was compatible. I’m guessing’ the real issue is that the FM231 is NOT a known device to the OpenMQTT Gateway so it’s unable to decode its RF signals. Looking for confirmation that the FM231 is or is not compatible. If it’s not compatible, can I configure OpenMQTT to add support?
