Hello everyone, I wanted to share my recent project integrating a smart doorbell with fingerprint access using OpenHAB and Shelly devices. It’s been a fantastic journey, and I hope my experience can inspire others!
The Setup
I’ve always wanted a seamless way to grant access to my home without fumbling with keys. After researching, I decided to combine a Shelly UNI with a fingerprint reader. The Shelly UNI acts as the controller, while the fingerprint reader handles the authentication. This setup allows me to monitor and control access remotely through OpenHAB.
Challenges and Solutions
One of the initial challenges was ensuring the Shelly UNI correctly recognized the fingerprint reader’s signals. After some troubleshooting, I realized the issue was with the signal type—AC vs. DC. By adjusting the wiring and adding a diode, I ensured the Shelly UNI could reliably detect the fingerprint input.
Integration with OpenHAB
Configuring OpenHAB was a breeze. I used the Shelly binding to connect the UNI and set up rules to trigger notifications when someone uses the fingerprint reader. This integration means I receive alerts on my phone whenever the doorbell is pressed or access is granted.
Benefits and Future Plans
This setup has significantly improved my home security. I can now grant temporary access to visitors without worrying about key management. Looking ahead, I plan to expand this system to include multiple entry points and possibly integrate RFID for even more convenience.
I’d love to hear your thoughts or any improvements you might suggest! Happy tinkering!
