Thirdreality Zigbee Vibration Sensor With 110Db Alarm, Hub Required,Adjustable Sensitivity, Work Smartthings, Home Assistant Via Zha/Z2M And Echo Devices Built-In

Put it on the washing machine to get a notification when it stops moving = is done.

Fonctionne bien, la sensibilité est satisfaisante et suffisante.

Pros: 1. Good build quality. 2. Pairs easily (Hubitat hub) 3. Two AA batteries will provide good life. 4. Able to turn alarm on/off. 5. Good sensitivity to vibration and movement. Cons: 1 Absolutely no way the alarm is 110 dB. Not even over 80.

Bought to make my washing machine smart per se, and to use with ZHA via Home Assistant. Like other ThirdReality products, this vibration sensor paired with no problem, fast. The sensitivity control is inside the unit itself, so to test, I left the unit on the desk for a while to see how sensitive it picks up the vibration after pairing before actually putting on the washing machine. Picks up fine with Medium sensitivity, but still monitoring the patterns for fine tuning. Wish this sensitivity control was via HA rather than opening up this device if needed. This doesn’t hugely affect the rating of this product for me, but some may think this is a blocker. By default with this unit, the alarm option comes enabled. Or at least mine did. This control also is inside the unit and it will beep while pairing if forgotten to disable it. I can confirm, really confirm, that it is loud! Loud is great for an alarm, but had a little hard time disabling this with my finger while pairing and ultimately using small screw driver to disable (turn the switch off inside the unit) with tiny force as I did not need this functionality for my use. I can see that this can be totally useful when used for home security. This isn’t the first ThirdReality products I own, and all of them have been pretty reliable altogether. Firmware OTA update is pretty sweet, and all of their products had no problem after upgrades.

I bought this to stick on my front door and integrate with Home Assistant so I’d actually know when delivery drivers knock, because too many just ignore the doorbell and it was driving me nuts. Setup was super easy and it paired straight away over Zigbee with my hub, and since then it’s been reliable and consistent. The device supports adjustable sensitivity levels, so you can dial it in exactly for your use case, which I needed to do because at first it was a bit too eager and giving false alerts. Once I dropped the sensitivity down it settled right down and now only alerts when there’s a real knock or vibration. It also runs on standard AAA batteries with a long expected life, so maintenance is minimal, and you can build routines off the vibration events in Home Assistant without needing any extra apps. Overall, this has worked exactly how I hoped once I tweaked the sensitivity. Simple to set up, reliable, and a great way to get notifications when someone’s at the door without relying on the doorbell alone.
