I have had multiple P1 motion sensors and have the same issue with all of them. They work greaat when I first set them up, but then months later they start loosing connection. I have tried changing batteries out, and also adding Zigbee repeaters (smart plugs) nearby. I’m using Home Assistant/ ZHA Integration. Anyone else have this issue and fixed it?
@justinsanker It sounds like you’re facing a frustrating situation with your Aqara Motion Sensor P1 losing connection over time. Let’s explore some potential causes and solutions based on the reference information available:
-
Distance from Hub: One common reason for sensors going offline is the distance from the Hub. Although you’ve already added Zigbee repeaters, ensure that the sensors are still within a reliable range.
-
Signal Interference: Avoid placing the sensors on or near metal surfaces, as this can interfere with signal strength.
-
Battery Check: Even though you’ve replaced the batteries, double-check that the replacements are functioning well and properly installed.
-
Check Hub Capacity: Ensure that your Hub isn’t exceeding its accessory limit. Some Hubs can only manage up to 32 connected devices.
-
Re-adding Sensors: If the problem persists, consider re-adding the sensors to your network as per the accessory adding methods.
If none of these steps resolve the issue, it might be beneficial to look into any updates or patches available for Home Assistant/ZHA Integration, or consult their forums for similar experiences. Community input can often provide unique solutions or workarounds. Keep us updated, and feel free to share any new findings!
@justinsanker It’s frustrating when devices that worked well start having connection issues—let’s try to figure this out! Based on common troubleshooting for the Aqara Motion Sensor P1, frequent disconnections after months could be related to a few factors.
First, even with Zigbee repeaters, the sensor might still be too far from the hub or the repeater placement might not be optimal. The P1 can struggle with signal if it’s too distant from the hub, so double-checking the sensor’s location relative to both the hub and repeaters could help .
Second, metal surfaces can interfere with the Zigbee signal. If the sensor is mounted on or near metal (like a metal door frame or appliance), that might cause intermittent connections over time. Try relocating it to a non-metal surface to see if that stabilizes things .
Third, while you’ve changed the batteries, it’s worth ensuring they’re high-quality CR2450s (some generic batteries might not provide consistent power). Also, if your hub has more than 32 devices connected, that could cause connection issues—check if the hub is approaching its device limit .
Since you’re using Home Assistant with ZHA, it’s also possible that integration-specific settings (like channel interference or firmware compatibility) could play a role, though this isn’t covered in official Aqara guides.
Have you tried resetting the sensors and re-adding them to the network? Sometimes a fresh setup can resolve lingering connection glitches .

@justinsanker It’s frustrating when devices that worked well start having connection issues—thanks for sharing your experience. Let’s look at some possible factors and troubleshooting steps based on common scenarios:
First, check if the number of accessories under your Hub exceeds 32. If there are more than 32 devices connected to the Hub, it might cause connection instability .
Next, confirm if the gateway (Hub) itself is stable. Sometimes, a gateway offline or weak signal can lead to sub-device disconnections. Try moving the sensors closer to the Hub and re-adding them to see if it helps .
You mentioned using Home Assistant with ZHA Integration—while we don’t have specific details on third-party integrations, ensuring the Hub is within a good signal range and not overloaded with devices is still key.
Have you checked if the Hub’s firmware is up to date? Sometimes firmware updates can improve connectivity. Also, if the issue persists, trying a factory reset of the sensors (following the reset steps in the app) and re-pairing might help.
