I swapped the battery on a Motion sensor but it’s staying offline.
Or, very confusing, it’s now saying it’s offline in the iPhone app and online in the “My Devices” tab online.
But it’s not working at all.
I really don’t expect to have to undefine everything and redefine just because I swapped a battery …
Yes, you’re right, normally swapping the battery should just work. What kind of motion sensor do you have? Depending on what kind you have will allow me to give you the right suggestions on what to do next. Usually a simple reset the motion sensor should get it working again. Occasionally, you might have to reboot the hub.
I got it working, but there is clearly a bug, or flaky code.
I reset the unit multiple times.
I reset the hub.
The thing triggering it to attach again was when I started the “add device” procedure on the app, which didn’t find any new device but triggered some piece of code to run and realize the device was back.
