I couldn’t find a keypad with the features I wanted for Home Assistant, so I built one with ESPHome.

A while ago I retrofitted an old alarm system with Konnected, which lets you expose the old sensors to Home Assistant and use the Alarmo integration to rebuild the system. It worked great, but using only my phone to control it got a bit annoying.

Picture this You’re coming in or heading out while the system is armed, you open the door, the delay starts, and you’re fumbling for your phone to disarm before it triggers.

Remote access is great, but for everyday use I'd prefer a dedicated controller. This build solves that with a fingerprint sensor for quick local auth, a keypad for PIN entry as fallback, and a status light.
