Intro

With zendō, you can effortlessly control your smart locks. Lock or unlock, pull the latch/spring (when supported), and check whether the door is open or closed. Keep an eye on the battery level of your smart locks in the Batteries section of the app.
zendō automatically detects if your smart lock supports unlatching or pulling the spring (common on some European doors). If unlatching is supported, the app will fully unlock the door.

Add smart locks to the floorplan

Add an accessory to the floorplan for each smart lock, next to the door where it’s installed.

Restrict access to smart locks

With Access Control, you can decide who can control your smart locks. In a home setup, you could hide them from kids and guests. In a commercial property, you could hide them from visitors and non‑admin staff.

Supported brands
