Assuming you don't need any C8 only features:
Do you think that it would be better (i.e. easier) to keep the C8 as a backup device - until the c7 dies?
Yes, because you'd be taking advantage of the Zigbee migration, so you could be up and running in 10 min or less using a C8, without the need to walk around the house resetting and re-pairing Zigbee devices.
That's what I've done this last year + with my C7. But now that the C8 is out, I'm not sure what to do.
Do I order one and wait for my C5 to die and totally skip the C7?
since my houes are empty i think i will eventually get another c8 for each house and have it configured and ready to go so a neighbor can just come in and swap it out if it dies..
wondering if i can use the hub protect to restore the configuration to the backup in order to have it ready to be swapped in. even though i don't have a failure at the time or can i just restore the cloud backup with both readios...
