door

homemade auto door opener — i hate keys

development of system

Relay + ESP32 + Cloudflare tunnel + iOS app setup to unlock the door of our summer rental house

Entirely self contained and self powered; since the logic for the door unlocking system I setup a 24 DC-DC converter that powers both the relay and the ESP32.

For reliability:

auto reconnect and discovery of network on ESP32
Docker container on my personal server that auto reboots on power loss

Also for ease of use, I setup an iOS app, shortcut, and widget. So you can tap a button on your homescreen or use Siri to open to door.
