I have more than 10 different open/close z-wave sensors on all my doors and windows spanning a few different brands. Early in December I started getting false “open” status from one of my sensors. This sensor reports 100% battery life and has been installed since May 2015. It seems to falsely report “open” once a week or so.
In late December a different z-wave sensor started doing the same thing (and does so to this day, just last night actually). This sensor also indicates 100% battery life and was installed in May 2015.
Finally today a third sensor falsely reported “open” while my wife and I were out and this set off my alarm notifications. As with the other two sensors, this one was installed in May and shows a 100% full battery.
I’m finding it impossible to now trust the status of my doors and windows because of this.
How should I go about trying to debug this issue and track down the cause?
