I did the battery pack upgrade to my sensors, two AA batteries instead of the coin. Both sensors worked great for months.
Then a couple weeks ago they started ‘leaving’ even when present.
So I put in fresh batteries; both sensors are reporting 100% battery since I did that last week.
They are still dropping out.
This morning, one of them ‘left’ for six minutes and then returned… without changing location whatsoever. It is in the same place it always is when it’s in the house, and nothing in my network has changed during this time. In fact, that sensor is within 10 feet of a smart plug - zigbee/zwave repeater.
I have rebooted the hub. Problem is still occurring.
Anyone have any ideas what might be occurring?
