Short version: The Tuya Zigbee motion sensor detects movement using passive infrared (PIR) technology. It works with Home Assistant through a Zigbee coordinator, using either ZHA or Zigbee2MQTT, which allows for local control. The main challenge is that the listing often includes both Zigbee and Wi-Fi versions, so you must choose the correct one for Home Assistant.

What the Tuya Zigbee motion sensor is
The Tuya Zigbee motion sensor is a small device designed to detect movement in a room or area. It uses a passive infrared (PIR) sensor, which means it senses changes in heat patterns, typically caused by people or large pets moving around. When it detects motion, it sends a signal to your smart home system.
The listing says this sensor uses Zigbee, which is a wireless language for smart home devices. Zigbee devices create a mesh network, meaning each device can talk to others, making the signal stronger and more reliable over distance. This sensor is typically powered by a coin cell battery, like a CR2450 or CR2032, which usually lasts for many months or even a year before needing a replacement. The listing suggests a detection angle of around 120 degrees and a range of 5-7 meters, which is typical for these types of sensors.
Home Assistant compatibility
This Tuya Zigbee motion sensor is designed to work with Home Assistant if you have a Zigbee coordinator. A coordinator is a USB stick or device that plugs into your Home Assistant server and lets it communicate with Zigbee devices. This allows for local control, meaning your sensor works even if your internet is down.
| Option | Works? | Notes |
|---|---|---|
| ZHA | Yes | Home Assistant’s built-in Zigbee integration. Requires a Zigbee coordinator. |
| Zigbee2MQTT | Yes | A popular add-on for Home Assistant. Requires a Zigbee coordinator and MQTT broker. |
| Tuya (cloud integration) | Likely | If you buy the Wi-Fi version or connect the Zigbee version through a Tuya hub, it can work via the cloud. Not recommended for local control. |
| Matter | No | Zigbee is a different standard than Matter. This sensor does not support Matter. |
| Local or cloud | Local | Works locally with ZHA or Zigbee2MQTT. Cloud required if using the Tuya cloud integration or a Tuya hub. |
Who it is for
This Tuya Zigbee motion sensor is for Home Assistant users who already have a Zigbee coordinator set up or are planning to get one. It is a good choice for budget-conscious individuals who need simple motion detection for automations, like turning on lights when someone enters a room. It is also suitable for beginners who want to expand their Zigbee network with an affordable sensor.
This sensor is not for those who need advanced presence detection, which can tell if someone is just sitting still in a room. For that, you would need a mmWave presence sensor. It is also not ideal for users who prefer Wi-Fi-only devices or do not want to invest in a Zigbee coordinator. If you need a more robust or feature-rich motion sensor, alternatives like the SONOFF SNZB-03P might be a better fit, though often at a slightly higher price.
How to set it up in Home Assistant
Setting up the Tuya Zigbee motion sensor in Home Assistant primarily involves pairing it with your Zigbee coordinator using either ZHA or Zigbee2MQTT. Here are the general steps for ZHA:
- First, make sure your Zigbee coordinator is properly set up and running in Home Assistant. You can check this under Settings > Devices & services > Integrations.
- Open Home Assistant and go to Settings > Devices & services.
- Find your ZHA integration card and click on Configure.
- Look for an option like Add device or Permit join. This puts your Zigbee network into pairing mode.
- Now, you need to put your Tuya Zigbee motion sensor into pairing mode. This usually involves pressing a small reset button inside a pinhole for a few seconds until an indicator light starts flashing. Check the specific instructions that come with your sensor, as this can vary.
- Once the sensor is in pairing mode, Home Assistant should detect it. Follow any on-screen prompts to name the device and assign it to a room.
- After pairing, the sensor will appear as a new device with one or more entities, such as a motion sensor entity. You can then use these entities in your automations.
Common issues and variants to avoid
- Wi-Fi vs. Zigbee versions: The most common issue with Tuya devices on marketplaces like AliExpress is that listings often sell both Wi-Fi and Zigbee versions under the same product. Always check the product options or description very carefully to ensure you are buying the Zigbee variant. The Wi-Fi version will not work directly with ZHA or Zigbee2MQTT.
- Pairing difficulties: If the sensor does not pair, try resetting it again and ensuring it is close to your Zigbee coordinator or a strong Zigbee router (a mains-powered Zigbee device) during pairing. Low battery can also prevent successful pairing.
- Battery life: While Zigbee devices generally have good battery life, factors like frequent motion detection or a weak Zigbee mesh network can drain the battery faster. If you notice unusually short battery life, consider optimizing your Zigbee mesh network tips.
- False triggers: PIR sensors can sometimes be triggered by sudden temperature changes, direct sunlight, or even pets. Experiment with placement to minimize false alarms.
Should you buy it?
The Tuya Zigbee motion sensor is a solid, inexpensive choice for basic motion detection within your Home Assistant setup, provided you have a Zigbee coordinator. Its main advantage is its low cost and compatibility with popular Home Assistant Zigbee integrations like ZHA and Zigbee2MQTT, giving you local control.
However, you must be vigilant when purchasing to ensure you select the correct Zigbee version and not the Wi-Fi variant. If you are looking for a simple, no-frills motion sensor to expand your Home Assistant automations on a budget, and you are comfortable with Zigbee, this sensor is a good option.
Frequently Asked Questions
Does the Tuya Zigbee motion sensor work with Home Assistant without the cloud?
Yes, the Tuya Zigbee motion sensor can work locally with Home Assistant. You need a Zigbee coordinator connected to your Home Assistant setup. This allows it to communicate directly without relying on internet access or the Tuya cloud.
Do I need a hub for the Tuya Zigbee motion sensor?
For Home Assistant, you do not need a separate Tuya hub. Instead, you will need a Zigbee coordinator, which is a USB stick or device that plugs into your Home Assistant server. This coordinator acts as the central point for all your Zigbee devices.
Should I buy the Zigbee or Wi-Fi version of the Tuya motion sensor?
For Home Assistant users, you should always choose the Zigbee version. The Wi-Fi version typically requires the Tuya cloud integration and a stable internet connection, which is less reliable and offers less privacy than local Zigbee control. Always double-check the product description and options before buying.
