Did the restore back to previous firmware and blocked internet access for my harmony hubs until this sorts out. Luckily only one of mine upgraded - I didn’t know they did that automatically.
I used a mac and here’s what I did:
- Download Harmony Desktop software for Mac from here https://support.myharmony.com/en-us/download
- Start the software - DO NOT CLICK IN WINDOW ANYWHERE AFTER LAUNCHING
- press option-F9 (may need to use the Fn key as well depending on keyboard)
- Choose your harmony from the list (I chose smart control) - select Factory Reset
- You’re taken to a page that has two steps
- Plug your hub into a USB port - wait until the buttons become active on the screen - took about a minute or more for me
- Click “Restore”
Your hub will be downgraded to the previous firmware (193 think). I did NOT do the factory rest.
After it was complete, I plugged it back in at my tv and everything worked as it did before. It appears to HA, etc.
