Hello! This is my first post in community. Please do not judge strictly and point out what can be done better. I am ready to improve and want to be useful.
I found an old smoke detector and an unnecessary esp 66. As a result, I got a smart smoke detection system.
In my opinion, my version is simpler than everything that I have seen on the net.
Briefly describe, then … “GND” ESP8266 I connect to the “GND” of the detector board. “Plus” the detector’s tweeters are connected to the assigned pin of the esp. In esphome I use the platform: gpio, mod: input. I add a filter so that the binary sensor works more correctly.
esphome configuration:
binary_sensor:
- platform: gpio
pin:
number: GPIO5
mode: INPUT
filters:
- delayed_off: 2s
name: "smoke test"
device_class: smoke
I made a video on YouTube, if you’re interested, you can watch:
