Add BIOMETRICS to your Smart Home – Fingerprint Sensor with Home Assistant
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.

what a master class! your videos are the best one when it comes to cool stuff to hassio
So I add my fingerprint and it works great. I add my friends fingerprint and it also works. I try scanning my finger after adding my friends and it fails, it says it found a match but instead of outputting my name it outputs "Unavailable".
Amazing project, I just built it following this video and it is amazing how simple it is with the clear instructions, thanks!!
I just found couple of small improvements, one is you can add this to the fingerprint sensor in Home Assistant so you are aware of the status of the sensor (available/unavailable):
availability_topic: "fingerprint/available"
payload_available: "online"
payload_not_available: "offline"
I also removed the "/" at the beginning of the topic to follow the standard of other devices
Hi. Good job. I have followed everything but I have a problem with the name that I cannot enter. Always unknown without being able to change it. I saw in the video that you were initially like that too. What did you do? Thank you
Quick question, is it possible to trigger a GPIO pin on the esp8266 after the fingerprint is recognized by Home assistant? Need this to unlock a 12v solenoid. Also you mentioned that you will do in another video about how to turn the led off when not in use.
By the way thanks alot for your hard work. My project worked.
Don't understand Blueprints, but could this this be turned into a standalone ALARM blueprint. Seems like it would be a good candidate for this, as it could be part of the building blocks of a modular security system.
Dope
what type of solder iron do you use?
Have you considered doing these videos shirtless?
Is it possible to do the same using esphome without mqtt?
You guys released these videos almost perfectly timed! https://youtu.be/Etm_8PNY1JU (Alarmo custom component) I presume that you could enable the MQTT feature on alarmo and set this fingerprint sensor to disable the alarm?
Not related to the fingerprint, but what device do you use to make those intermitents beeps while not authenticated with fingerprint? Is it alexa? If so, how did you do it? Thanks, your videos are awesome.
I've been stuck with this since March, thanks for the video
Just a FYI, you want to learn in at least two or a maximum three finger prints. All it takes is something to disrupt the finger print and becomes useless such as a blister, blood blister, cut, or even the extreme loosing a finger.
Hi…I had made a small project where I was storing the BLOB file containing the fingerprint object in an SD card, so is there any way of storing that file in the cloud or some other remote storage?
Great tutorial! The LED control would be a great feature to add.
For example if it's not expecting a fingerprint, turn off the LED so its not shining up the wall, but enable it when you need to use it.
(for example, while the system is armed it could be on, off when not)
I am considering making one for my daughter (shes 2) to play a song for her in the day time, or turn on her lights after sunset (as she cant reach the switch!) – the green light may tick the box for a nightlight for her too!
Good work dude! I'm planning to implement this in my home alarm system!
Another great tutorial. thank you.
Very Cool, Would be great if your fingerprint code could be used with https://esphome.io/ like a rfid tag (https://www.home-assistant.io/blog/2020/09/15/home-assistant-tags/)
Very very cool! I ordered the fingerprint reader before the video was over! Another good one! Keep it up!
