Hi guys, I was wondering if anyone had realized, even for personal use, an inexpensive smoke (gas) detector that uses MQTT to communicate with Home Assistant.
For the purpose I found an “MQ-2 Smoke Gas LPG Butane Hydrogen Gas Sensor” on Aliexpress, but with regard to the software side I did not find anything online (at least not within the reach of a newbee like me).
It seems to me a good idea to be implemented, especially for technology enthusiasts who have many devices on constantly.
I’m using a NodeMCU to read from a MQ2 among other things (control a switch, a relay, read temp/humidity/pressure, a pir, and a buzzer) all via MQTT, there are lots of examples out there Google is your friend
