Iris V2 contact sensor

I am on version 2.3.5.131 on C8 hub. I am having random Iris V2 contact sensors that have been fine for years, starting to show an inverted state, showing open when closed. Batteries, replaced, devices reset, nothing makes it go back to normal. Not all at once, usually one at a time will do this. I rest one multiple times today, and it started working. all was good most of the day, then I was just sitting here and another one alerted that it opened, but the door is closed. it is working exactly opposite of how it would normally work. Something in the Zigbee? @mike.maxwell

Were you seeing this with 2.3.5.130? That is what I am using and I have not seen this with my Iris V2 sensors. You may wish to revert to 2.3.5.130 and see if the behavior persists. If not, then it is possible that there is a problem with the 2.3.5.131 update.

I've seen enough issues reported on .131 to avoid. I'm still on.125 and everything is solid.

I removed it completely and recommissioned, now all is good.
