I have three Multipurpose Sensors in my home (among several other sensors and switches). One monitors just motion, one monitors open/close and one monitors both motion and open/close. None of them are responding today. The last activity on all three shows the same 17 hours ago. All have been tested a few minutes ago and there is still no response on any of them. All SmartApps have been selected and re-saved with no results. Can anyone suggest what to try next?
No expert in that regard, but I would pull the batteries for at least 15 min and then replace. Probably reboot my hub while they are out and waiting.
Like @JH1 said, try taking the batteries out for 15 seconds and then put them back in. And follow up with support ticket if that doesn’t solve the problem.
