Help a novice please…

Thanks for the help, much appreciated.
I finally got to the bottom of the problem, to summarise:

  1. It appears there was some sort of problem (dip) with the power during the night, not enough to knock everything out but enough to reset the C8 and my router, so I didn't know about it, (email msgs went down) but everything else was working and I hadn't touched the C8 for 3 or 4 days.

  2. The C8 rebooted with the internet still down, SO, it switched to WiFi.

  3. When the C8 goes to WiFi it does NOT go back to ethernet, even if i reset the interface with the little button (lots of times).

  4. The C8 was on its own WiFi network setting that doesn't seem to broadcast its name/ssid etc.

  5. To add to my problem my M2 laptop is happy to load and run the Hubitat app, but it doen't work, it gets stuck looking for a hub with no way of getting out of that page.

Thanks Heaps,
Richard.....
