Description
A Zigbee 3.0 vibration and tamper sensor (model ZG-103Z) that detects shocks, knocks, and tilt – useful for door / window break-in detection, valuable-object monitoring, and tamper alerts on safes or cabinets. Reports events to your hub within a fraction of a second so automations can fire immediately.
Pairs with any Zigbee 3.0 coordinator: Home Assistant (Zigbee2MQTT or ZHA), SmartThings, Hubitat, Philips Hue Bridge, Aqara Hub, or Echo with built-in Zigbee. Fully local – no cloud dependency, no internet round-trips.
What it detects
- Vibration / shock – any sudden impact above a configurable threshold triggers an event.
- Tilt – orientation changes are detected and reported separately.
- Glass break (with placement) – mount on a window pane and the sensor detects the high-frequency vibration of glass cracking before it shatters.
- Drop / fall – useful for shed, garage, or door-side mounted detection.
Practical uses
- Window break-in detection – mount on the glass pane of a ground-floor window, get an alert the moment someone forces it. Faster than a contact sensor (which only triggers after the window is opened).
- Safe / cabinet tamper – stick it on the back of a safe, jewellery box, or drawer. Any movement or vibration triggers a notification.
- Bicycle / motorbike monitoring – attach to the frame inside a shed or garage. Catch theft attempts in progress.
- Front-door knock detection – useful when you can’t hear the doorbell – the sensor catches the knock vibration and triggers a notification.
- Washing machine cycle detection – use the vibration pattern to detect when the machine starts and stops; notify when laundry is done.
- Garage door movement – mount on a roller or up-and-over door – catches both opening and tampering attempts.
Hub compatibility
Standard Zigbee 3.0 device using the IAS Zone cluster (the standard for security sensors). Works with:
- Home Assistant (Zigbee2MQTT or ZHA) – fully local, separate entities for vibration, tilt, and battery. Sensitivity adjustable via Zigbee2MQTT.
- SmartThings – paired via the Generic Zigbee Vibration / Shock Sensor driver.
- Hubitat – built-in driver, exposes vibration events.
- Philips Hue Bridge – paired as a third-party Zigbee 3.0 device.
Battery life
CR2032 coin cell (included). Typical battery life is 12+ months with normal use (a few events per day). Heavy use (lots of detected vibration) reduces this. Battery state is reported to the hub for low-battery alerts.
Installation
- Insert the CR2032 battery (pre-installed in some shipments).
- Put your Zigbee hub into pairing mode.
- Press the small button on the sensor body for 5 seconds; the LED blinks during pairing.
- Once joined to the hub, mount the sensor using the included 3M adhesive pad.
- Adjust sensitivity if your hub supports it (Zigbee2MQTT exposes the configuration parameter).
Great little sensor. I got it expecting it not to work well with Home Assistant, but worth a punt as it was so cheap. It does exactly what I need and works great with ZHA.
Works as expected
The sensor does exactly what I need it to do. I have it on a none opening window.
exellent sensors with 3 sensativity settings i use these outdoors as fence perimeter sonsors and install them in waterproof electronic enclosures, add them to you alarm system for complete peace of mind
Device works well. Had to write custom controller for Zigbee2MQTT, though I suspect it will be supported soon anyway.
Not supported directly by Zigbee2MQTT but I managed to get it working by hacking a new YAML config. I’ll upload to Zigbee2MQTT Github so all can enjoy it.
Didn’t work with Smartthings even though it was listed as ZigBee compatible
It does work with Hubitat – but you need a community custom Tuya Vibration Sensor Driver, which you can download and install via the Hubitat Package Manager (a user created app). Works very well, 6 levels of sensitivity (with the custom driver on Hubitat). I stuck mine to an old, dumb, hardwired smoke alarm system to pick up the alarm and send a notification if it goes off. Works nicely on the lowest sensitivity level. It’s quite small – 4x4x1cm.
