Sonoff RF Bridge with Tasmota - RF Smoke alarm #4

Closed jat80 closed 2 years ago

jat80 commented 2 years ago

Hi there,

I'm just wondering if this plugin will help me setup some RF Smoke alarms using my Tasmota flashed Sonoff RF Bridge.

If so is there anything special in the config that I will need to do as each smoke alarm will have it's own RF code.

Thanks for your time.

Hi I have a very similar setup at home: several smoke sensors with RF433 capabilities, and a Sonoff RF bridge flashed with tasmota (9.5.0) to receive the radio messages. I then setup some rules inside tasmota like this one:

rule1 on System#Boot DO Backlog publish2 tele/smoke_alarm_garage/STATE off ENDON on rfreceived#Data=63F076 do publish2 tele/smoke_alarm_garage/STATE on endon

This way any state change will trigger an MQTT message.

On the homebridge setup, a new accossory is created like this: 

        {
            "accessory": "mqtt-tasmota-smoke",
            "name": "Fumee Garage",
            "url": "mqtt://my_server",
            "topic": "smoke_alarm_garage"
        }

The only problem so far is that when a smoke sensor is triggered, I have to manually publish an 'off' message on the MQTT topic to reset the state (Hopefully fires in the house are not happening often!).

Hope this helps. Cheers
