Does anyone know, which sensor can be used to detect burning of insulation? Standard standalone smoke alarm did not work for some reason. Thank you!

DIY? [image] ESPHome based Smoke Alarm ESPHome I just finished mine nerd_face I used: ESP8266 MQ-2 gas/smoke sensor GY-302 illumination sensor (just for fun wink) So now in HA I have: binary sensor calibrated via potentiometer on MQ-2 sensor of gas (%) converted fro…

Yes, DIY is perfect, thank you, I will check this gas sensor ASAP. PS: sensor bought, waiting for delivery.

What kind of inulation? Electrical or residential building insulation? Either way I’m surprised it didn’t work based on the type of smoke. I wouldn’t think there would be any special properties of that type of smoke to make a smoke detector ineffective.

Electrical. Yap, I am surprised to. Maybe smoke concentration was not enough to trigger the alarm. That’s why I want to add configurable sensor, to be able to adjust threshold ranges manually or with some automatization.

What sensor can be used to detect burning of insulation?
