@csuk I have 2 of the coin battery ST multi sensors both showing 66% life left. One multi is clearly dead as it has not posted anything for days. The other is used on a garage door but not longer is showing anything except always closed, However it is still reporting temperature at the regular interval. I have some new batteries coming to the house tomorrow, but am curious if the second multi is a battery issue as temp still reports fine. I have also opened a support ticket over the weekend, but have not heard back on that yet. Any thoughts here? Hopefully it just takes a fresh battery. We will see
