I perhaps ought to link this thread to my extended comments in Hub Backup woes.
I don’t know if the ‘hub replace’ shares any of the same issues as ‘hub backup’ as I haven’t used it lately. Currently I am sticking to a hub group (with automatic backup disabled) purely because it gives me multiple TBRs on the same Thread network. Or at least I assume it does. I’d be a lot happier if I could also do that with standalone hubs.
