Alright, so here’s the tea—my Aqara motion sensor totally ghosted me outta nowhere last week. One day it’s catching every move like a hawk, the next it’s just chilling like a dead rock. Zero triggers, zero response even when I did the whole ninja dance right in front of it.
I almost tossed it, but figured I’d poke around first. Turns out, it wasn’t dead, just… really moody. What worked for me was removing the sensor from the hub completely, resetting it manually (hold that tiny button till the blue light goes nuts), then re-adding it like it’s brand new. After that, boom—it’s back, sensing, logging, and automating like nothing ever happened.
Also, double-check your Zigbee network, especially if you’ve added new devices. I didn’t realize one of my smart plugs had gone offline and that totally messed with the mesh.
Anyone else had their motion sensor ghost without warning? Curious if it’s a common thing or my setup’s just haunted.
@GoogleHomeGuru Hey there! Thanks for sharing your experience with the Aqara motion sensor—it’s always helpful to hear real-world troubleshooting stories. Your approach of resetting and re-adding the sensor is spot-on! According to Aqara’s documentation, this is often the best fix for unresponsive sensors. Here’s why it likely worked:
- Reset & Re-add: Pressing the reset button (for ~3 seconds until the light flashes) clears any glitches and forces the sensor to re-establish communication with the hub. The hub’s “Normal link confirmed” voice prompt confirms it’s back online.
- Zigbee Network Health: As you noted, offline devices can disrupt the mesh. Sensors rely on a stable network, so your tip about checking other devices is gold!
For others facing similar “ghosting,” here are quick checks:
- Battery: A dim reset button light often means low battery (CR2032 replacement needed).
- Placement: Metal surfaces or distance from the hub can interfere. Try relocating it temporarily.
- Sleep Mode: Sensors trigger every 5 seconds initially, then switch to 1-minute intervals after an hour of inactivity.
Your haunted setup might just need a little TLC!
