All switches stopped working

I have zooz light switches, have had them for a few years with no issue. The physical switches still work. When I turn them on using hubitat now, nothing happens. I look in the log and I can see that the command was sent. I updated the hub and restarted it with no success. The switches are on multiple different circuits in the house.
Any ideas?
Of note I also have ecobee integration, and that works fine from the dashboard.

Needs more details. But the first thing to try is:

  1. Shut down the hub from the Settings page.
  2. Cut power to the hub.
  3. Restore power to the hub.
