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 of…

There are a couple of posts about this issue and sounded like quite a few of us are having the same problem. The new firmware and the health check probably are the cause. I have health check disable and seem to be working for now.

From what I’ve seen, SmartThings changes the status of all the devices every time the hub goes offline. When the hub comes back online it doesn’t change the status of the devices back to online so the devices appear offline until the next time they have activity. That’s not really an issue for dev…

Thanks for the tip, I know that my router tends to get fatal errors and will reboot itself every few days or so. That is probably causing the hub to go offline for a few minutes. I will try your suggestion the next time it happens or maybe just turn off health check altogether.

Happening to me too, I’ve got 3 offline device at the moment. Really annoying to babysit smartthings. No idea why a simple health check would cause them to go offline…

I went around and reset all my sensors and now they seem to be working fine. I’m still not sure what caused them all to go offline but it may just be coincidence or possibly the health check option in the new app as some have suggested. Even so, I still have my health check option still enabled.
