I'm sure this has been asked before, but my searching ability seems to have failed me.
I have a bunch of Smoke/CO sensors that are working fine in terms of sending alerts and like that, but none of them seem to update their battery status. Many months since installation all of them are still above 77% and two are still 100%. Two of them started beeping because of a low battery and have new batteries. Neither of those are the 100's but I do know that they both showed a high number while they were beeping before I gave them new batteries.
They are listed as Vision ZS6101 devices. The wakeup interval is the default (30 minutes) and polling is blank (default).
Thanks,
Craig
