I shared this on Reddit over the weekend but thought I’d share it here too for anyone who wanted to check it out, its a quick demo of a fingerprint sensor working within HASS over MQTT, something I had not seen before (not to say someone else hasn’t done it!)
When I was trying to look for information on this I saw quite a lot of people asking the question of how to do this but no answers, so decided I wanted to document everything in case it helps anyone else, since I saw a lot of people struggling with it.
Full guide coming soon but essentially its an esp8266 board (Wemos D1 Mini in this case) connected to Home Assistant via MQTT, and powering an FPM10A Fingerprint sensor. It can remotely enroll new fingerprints and delete old ones without reprogramming (something that is frustrating about the original code) and seems to be pretty snappy. It can store 127 fingerprints too.
Hope you like it, more details will hopefully be coming really soon.
