Have had motion sensor downstairs and upstairs tied to hue bulbs for a few years now (insider tester in uk) and had very few false trips but over the last 2 months my sensors are useless. 1 of these is less than 6 months old. We have been away all day today and take a look at the attached log. I had to turn off the turn on lights on motion as the house was like a disco at night.
The sensors and hubs have all been reset and rejoined. Batteries are at 67% on both devices. It’s become so bad recently im thinking of changing to different sensors. Anyone else having this issue as it seems software related to me.
If these are SmartThing branded (Centralite) , I bet if you change batteries they will work as expected. As many others have said, battery level readings are not accurate. I have had many different SmartThing brand sensors die/drop off with last reading of 67% without warning. False activations too. When I pull battery and measure with DVM they read up to 2.82V. The motion sensors drop off and give false readings when volts are around 2.8. The multi seem to be useable down to about 2.67V
I learned to use Simple Device viewer to monitor since you cannot rely on the built in health reporting either. I cannot use Home Armed mode of SHM because all the false activations waking me and the wife.
The only problem, the developer has jumped ship to Hubitate Elevated platform and the GitHub location is broken. I can give you my copy af the code, just PM me your e-mail and I will give you a link to my storage.
