When ST did a hub update several months ago, just before the Holidays I started to have issues where my ST motion sensors (ZigBee) would send false positives and wouldn’t stay connected to the hub. At the time it was deemed to be associated with the OTA update feature they enabled. I tried everything they recommended and couldn’t seem to get the ZigBee devices to be stable.
In late February I decided to try again. I replaced every battery, pulled power/batteries and remade the mesh. I managed to get all but 2 of my 16 motion sensors working again. One is just flat dead, the other continued to give repeated false positives. Of the 14 remaining, I managed to get all of them updated via the OTA update feature.
All was relatively well until 2 nights ago. All of the sudden we had two sensors start throwing motion events every 8-12 minutes (almost like it was on a schedule it was so routine through the night.) Unfortunately, one of those was in our bedroom and controls our dim lights to the bathroom and night stand. So after turning off the lights once or twice I realized that something was going on…
Today, I started having the ST motion sensors drop offline again just like back in December… But I don’t think there was an update recently and I haven’t changed anything in the past week. None of my Ecolink or Aeon sensors are showing the same symptoms. None of the ZigBee door/window sensors or even the ST flood or humidity sensors seem to be affected either…
Is there some other known cause that I missed between the holiday update and now or is it just these ST motion sensors?
