Having a Smart Home Door Closer has been a vision of mine for over a year. But to my surprise nobody made one, so I decided to make my own. After months of trails & tribulations and probably a thousand dollars of different parts, I finally have a smart door closer that works great. Not only does it work in HomeKit, but you also set this up with Alexa and Google Home, if you use those platforms. I look forward to seeing what other people come up with to make this project better and hopefully we can come up with a safer DC/battery option.

DO THIS AT YOU OWN RISK - Playing with electricity, motors, wires & relays could be dangerous!
