another thing I noticed too, is that when I make the appointment, I receive the online status notification, however, nothing happens to the device, it doesn't change the status and it doesn't show map position
Are you using an official release without any changes to the code or configuration?
By the way, please enable full stack traces so we can see the full error for the second issue.
Yes, trace official, no. Version 5.4. Tell me if this is what you need:

It looks like there's some issue with the group. Have you removed any groups?
We didn't even create a group. Is empty.
The error message says otherwise. Please provide API response or the database record.
Hello everyone, after we update our system to 5.4, almost all devices are still offline, even after reset and reconfiguration, they don't go up in the system anymore. Only a few so far are online.
