Create routines, automate lighting based on motion detection. Requires Zigbee hub. Review: Really good little motion sensor with long battery life - This is a very good little motion sensor Im using with Home Assistant to switch on and off a light in the downstairs bathroom. It connected to my Zigbee hub instantly and has worked flawlessly since I installed it. Simple, small and long battery life (obviously depending on how often its triggered). Review: Works with Home assistant. - Great little motion sensor. Very responsive and paired immediately with ZHA. It's basic enough, though and doesn't report luminance, only motion. It runs on 2 AAA batteries. I've been experiencing issues with Aqara motion sensors, including the original one and the P1, so I'm on the hunt for a reliable motion sensor. I'm trying out the Candeo one at the moment. At 15 euros, you can't go wrong with the candeo. ## Features - ZIGBEE STANDARD COMPATIBLE MOTION SENSOR: A Zigbee Hub is required.

Got this in the b/Friday deal but still good price. Long detection distance got it set up in the hallway and picks up motion straight away from opening front door which is about 18ft. Great automations with other devices i.e. lights works instantly (am using with Zigbee) Defo recommend will be looking at more from these guys. ## Frequently Bought Together - THIRDREALITY Zigbee Motion Sensor, Pet Friendly, Compatible with Home Assistant, SmartThings, Aeotec, Homey, Hubitat or Echo Devices with Built-in Zigbee Hub - THIRDREALITY ZigBee Smart Plug 4 Pack with Real-time Energy Monitoring,15A Outlet, Zigbee Repeater,ETL Certified,ZigBee Hub Required,Work with Home Assistant,Compatible Echo Devices and SmartThings - THIRDREALITY Zigbee Contact Sensor, Door and Window Monitor, Home Automation, Works with Home Assistant, SmartThings, Aeotec, Homey, Hubitat or Echo Devices with Build-in Zigbee Hub,hub Required --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/385955338-zigbee-motion-sensor-1-pack-zigbee-hub-required-pet-friendly](https://www.desertcart.co.uk/products/385955338-zigbee-motion-sensor-1-pack-zigbee-hub-required-pet-friendly) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
