I think you wrote the Advanced Device Driver for this. I have it installed via HPM and have 3 of the Zooz ZAC38's as part of my ZIP Mesh. I use them for both a range extender and indicator of power outage or issue with a key breaker.
I get this error on all 3 devices about once per day.
Could be due to a change with the scheduled jobs I made.
Make sure driver is updated to 1.0.6 version, run REPAIR in HPM if not sure.
Run Configure on each of them.
Refresh the device page and check the Scheduled Jobs tab, you should have "Once" scheduled events. The old way I was doing it was a recurring task but the new version removes that and does it this way instead.
All this does is ping an http address once a day so I can get a count of how many people/devices are using the drivers. Nothing else is tracked, just a count.
