I can't remember the last time we had a power cut here, but some might be on their way with this unusually hot weather (the UK goes into disarray with one flake of snow, remember).
From searching, I notice some people lost their hubs altogether, and had to replace them. But what is the normal experience? Is it worth buying a UPS? I have backups, and subscribe to that plan that backs up your z-wave data. If I got a UPS is there a way to use the "shutdown" option on them with hubitat?
