In this video we are taking a look how to build a fingerprint sensor or scanner with Home Assistant that you can use to add biometric scanning to your Smart Home. I’ll show you step by step how to build this sensor, how to program it and how to integrate it with Home Assistant, as well as how to remotely add and remove fingerprints.
This fingerprint sensor is built on MQTT meaning you should be able to use it with any platform that supports MQTT, be it OpenHAB, Domoticz, Hubitat etc.
