Zooz ZSE43 Tilt/Shock XS Sensor

Quick verdict

Stick the ZSE43 on your garage door and Home Assistant instantly knows if it is open or closed. Also works on cabinets, gates, and mailboxes, anything that tilts or gets bumped. Dead simple setup, tiny form factor, and cheap enough to not overthink it.

Standout: Stick-on tilt and shock sensor for garage doors, cabinets, and gates. No wiring needed.

Compatibility snapshot

Why it stands out

• tiny XS form factor mounts anywhere with adhesive, including garage doors, cabinets, and mailboxes
• detects both tilt (open/close) and shock (vibration) events
• no wired sensor needed for garage door monitoring, just stick it on the door

Reasons to hesitate

• tilt detection has a slight delay compared to a wired contact sensor
• battery is sealed in the XS design and is not user-replaceable
• Z-Wave range can be an issue in detached garages far from the controller

Best for

• garage door open/close monitoring without wired sensors
• cabinet, gate, or mailbox monitoring where a contact sensor will not fit

Avoid if

• you need instant, reliable garage door state, since a wired tilt sensor is more dependable
• your garage is far from the nearest Z-Wave repeater
