Buyers often report good performance for both motion and light sensing, making it a versatile option for smart lighting and presence detection.
How to choose
How to choose a Zigbee motion sensor
Choosing the right Zigbee motion sensor for your Home Assistant setup involves looking at a few key factors to make sure it meets your needs.
Protocol and variant
Most of the sensors here are Zigbee, which is excellent for Home Assistant because it allows for local control. However, some Tuya listings might offer both Wi-Fi and Zigbee versions. Always double-check the product title, description, and even customer reviews to confirm you are buying the Zigbee variant. A Wi-Fi version often requires the Tuya cloud integration, which relies on an internet connection.
Local control
For Home Assistant users, local control is usually preferred. All the Zigbee sensors in this guide should work locally with a Zigbee coordinator and either ZHA or Zigbee2MQTT. This means your automations run faster and do not depend on an internet connection or a manufacturer’s cloud server. Learn more about Wi-Fi vs Zigbee vs Z-Wave vs Matter explained.
Power source
Most Zigbee motion sensors are battery-powered, offering flexibility in placement. Check the battery type (e.g., CR2032, CR2450) and how long the battery is expected to last. Sensors with larger batteries often last longer but might be slightly larger in size. All the sensors listed here use common coin cell batteries.
Additional features
Some motion sensors, like the Tuya Zigbee motion brightness sensor, include extra features such as a light sensor. This can be very useful for creating smarter automations, for example, only turning on lights if it is dark and motion is detected. Decide if these extra features are worth the slightly higher price for your specific automation goals.
Setup notes for Home Assistant
Setup notes for Home Assistant
Adding Zigbee motion sensors to Home Assistant is usually a straightforward process if you have a Zigbee coordinator set up. Here are the general steps:
Using ZHA (Zigbee Home Automation)
- Open Home Assistant and navigate to Settings, then Devices & Services.
- Find your Zigbee coordinator under the Integrations tab and click Configure.
- Select Add device. Home Assistant will start searching for new Zigbee devices.
- Put your motion sensor into pairing mode. This usually involves pressing and holding a small button on the sensor for a few seconds until an indicator light flashes. Refer to the sensor’s manual for exact instructions.
- Once detected, follow the on-screen prompts to name your device and assign it to an area.
- The motion sensor will appear as a new device with entities for motion detection (and brightness if supported) in Home Assistant.
Using Zigbee2MQTT
- Ensure Zigbee2MQTT is running and accessible.
- In the Zigbee2MQTT web interface, go to Settings, then Permit join. Turn on the toggle to allow new devices to join your network.
- Put your motion sensor into pairing mode, typically by pressing and holding its button until a light flashes.
- Zigbee2MQTT should detect the sensor and automatically add it. You can then rename it and configure its settings within the Zigbee2MQTT interface.
- The sensor’s entities will automatically be discovered and appear in Home Assistant.
For optimal performance, consider placing your Zigbee coordinator centrally and refer to our Zigbee and Thread mesh network tips for Home Assistant.
Frequently Asked Questions
What is a Zigbee motion sensor?
A Zigbee motion sensor is a smart home device that detects movement using the Zigbee wireless protocol. It communicates with a central hub, like Home Assistant with a Zigbee coordinator, to trigger automations such as turning on lights or sending alerts.
Do I need a special hub for Zigbee motion sensors?
Yes, to use Zigbee motion sensors with Home Assistant, you need a Zigbee coordinator. This is a USB stick or a dedicated gateway that plugs into your Home Assistant server and creates the Zigbee network for your devices to connect to.
Can Zigbee motion sensors work locally with Home Assistant?
Yes, Zigbee motion sensors are known for their ability to work locally with Home Assistant. Once paired with your Zigbee coordinator and integrated via ZHA or Zigbee2MQTT, they do not require an internet connection or cloud service to function, ensuring faster responses and better privacy.
