SNZB-03 motion sensor: False positive every 3 hours

Configuration Zigbee

Hi All,

My Sonoff SNZB-03 motion sensors is sending false alerts precisely every 3 hours.
It’s connected to home assistant via a flashed sonoff ZigBee bridge.

Can anyone suggest any cause or interference which might be responsible for this?

Regards

Dave

I had the same issue, maybe more frequent than your timings. I sent em back and got Philips hue ones. Not had a single false since installing them over a year ago. Battery still 100% too.
They are expensive, but worth every penny.

Are you able to send a link to the model you purchased?

I have bought about 8 of the SNZB-03 Motion detectors and stopped using them because of the false positives. I believe I found away to use them. I created a group to hold two sensors. I set the group settings to “All” this forces the Group to only turn on when both sensors in the group turn on at the same time. This is a work around and it seems to work. I only use these to turn on lights, not to trigger an alarm system. These sensors only cost me $5, I can afford to use to each were applicable.
