Multiple sensors go offline in a particular room of my home suddenly

I have a bunch of vibration,motion,humidity sensors in my kitchen that were working fine for ~year. Seems like all at once majority went offline…all with “excellent signal and normal battery”. I paired them back up, but a few dropped to offline again.

I thought Aqara wired switches work as repeaters …So why loss in signal? And why all lost signal at the same time with good signal and battery after working fine for the last year?

Hello @sellerama916
Try replacing the batteries regardless of their charge readings in the app; some sensors, especially the first versions, cannot correctly transmit charge readings.

So l did replace a few batteries in some of my sensors and repaired them and those were running good.

2 other motion sensors l ran out of new batteries…got around to replacing them yesterday…and now the original sensors went offline again.

What is going on? 5 sensors go offline all at once. Replace 3 batteries, then other 2 batteries, and the first 3 go offline again
