I have 3 devices that are showing up in the device list as follows:
OFFLINE - Living Room T Stat on Hubitat. The Disabled slider is set to disable.
Checking the slider or going into the device and clicking Enable is not enabling the device.
Two are Radio Thermostats a CT100 and a CT101.
The have been on the hub for a while.
Do I need to remove and re-add?
That explains it.
No, the three devices were on a C5 hub. It died and I moved them to the C7. All was working until recently. No idea why the C7 reverted to an old configuration by itself.
