Motion Sensor V2 with Home Monitoring Useless

[SlabSlayer]

Mine are all over a year old. Many with the original batteries. All are still operational. I had 3 that gave me the same problem, but I fixed it:

Motion sensor false alarm

I had a similar experience with 2 unruly sensors back in February. Reset, battery change, reset, delete, add solved the problem after they sat without the battery for a bit. Since then, another started false alarming and I moved it inside from my garage and it stopped. Back in the garage and it started doing it again. Found out it doesn’t like cold. Swapped it with an inside one and all is well. Currently all originals are operational, most on original batteries, a year later.
