KI sagt:
The Philips Hue Motion Sensor (SML001) often fails to report activity, shows "unavailable," or displays no history in Home Assistant (ZHA or Zigbee2MQTT) due to issues with how it handles Zigbee network rejoining, battery changes, or network range.
Here are the most effective solutions based on community experiences:
1. The "Allow Insecure Rejoin" Fix (Most Common Cause)
Many SML001 sensors fail to reconnect properly after a reboot or network hiccup because they require "Allow Insecure Rejoin" to be enabled on the Zigbee coordinator. Without this, they connect but report no data.
- ZHA: Go to Settings > Devices & Services > ZHA > Configure. In the network settings, ensure "Allow Insecure Rejoin" is enabled. You may need to restart Home Assistant.
- Zigbee2MQTT: This is usually enabled by default, but check your configuration if you are experiencing issues.
2. Force Re-Configuration
If the device is "online" but shows no state changes (motion, illuminance, temperature), forcing a re-configuration can fix it.
- Go to Settings > Devices & Services > ZHA.
- Click on your Philips Motion Sensor.
- Click the three dots in the top right, and select Reconfigure.
3. Pair via a Router (Not Direct to Coordinator)
The SML001 can be picky about pairing directly to a USB coordinator (like Sonoff or SkyConnect).
- Pair near a Router: When adding the device, use the "Add Device" button within the ZHA interface via a powered zigbee device (light bulb, wall plug) close to where the sensor will be located, rather than directly to the stick.
- Move & Pair: If that fails, move the sensor right next to your coordinator, re-pair it, and then move it to its final location.
4. Replace Batteries / Clean Contacts
The sensor is highly sensitive to voltage drops. Even if it shows 50% battery, it may not have enough power to send data packets. Replace with fresh CR2450 batteries.
5. Check for "Occupancy" vs "Motion"
Since 2022, ZHA might show "motion" instead of "occupancy" or show "unavailable." Using a specific blueprint to handle the IAS Zone cluster can help it function more reliably.
Summary of Actions
- Enable Allow Insecure Rejoin in ZHA.
- Fresh batteries.
- Reconfigure in ZHA.
- If it still fails, factory reset the device (hold button 10+ seconds) and re-pair through a nearby Zigbee router.
