My Hub firmware is 000.054.00014 and my Bridge installation stopped working about a month ago too. I do have two Hubs at different residences, but this was working before. Hitting any of the Harmony activity “devices” now results in no action at all. I have untoggled and re-toggled the “Activity Devices Enabled?” setting under Harmony Bridge, no effect. “Harmony Command” says “Not assigned” - problem?
I would suggest using the ST CLI to do driving logging to see if there is some indication of what is happening.
It just installed successfully!
No idea what changed…
Now to set 3 hubs back up…
