After several months of successful use, I wanted to share my DIY smart doorbell project with the community. The goal was to create a cost-effective solution that would ring all my FRITZ!Fons simultaneously without any Crosstalk. Additionally, I wanted the ability to unlock the door remotely and receive a live feed from the person at the door. Integration with Home Assistant was also a key objective, allowing me to mute the doorbell or unlock the door via the HA app.
I designed a small PCB and connected it according to the following schema. The PCB automatically integrates with HA via MQTT discovery. For the live feed, I used a Reolink RLC-410 IP camera, which also serves as the live picture source for the FRITZ!Box IP door intercom system. The camera is integrated into HA using the HACS Reolink IP camera integration.
For those interested in replicating this project, I’ve published all the details on GitHub. I’d love to hear about your experiences or if you’ve implemented similar solutions!
