One nice thing about the new mobile app is to quickly be able to see if a device goes offline with the health check option. Things have been working great for me for nearly a year with only one or two devices here and there dropping off but I wonder what could cause more than twelve devices to go offline at once? They are all battery-powered devices, it includes Iris contacts & motion sensors, PEQ contacts and leak detector, Samsung branded motion sensors and contacts. None of my pocket outlets went offline so I’m guessing that I should still have a strong mesh.
I checked all the batteries when I went around to re-activate the devices and they were all good. A few sensors would work for about a day and then go offline again so I would have to reset again. I also did a cold reboot of the hub. Finally, I decided to enable OTA firmware update on the hub so I’m hoping that might help fix things.
I have read about others having a similar situation where multiple devices would drop off at once. I guess it’s my turn. I’m slowly bring them back online but a few devices are being stubborn. This may only be anecdotal, but it seems like I have the most problem with my Zigbee devices.
