I hope the Batrium guy don't mind, but this is what they suggested:Super random. sometimes it does nothing and sometimes it freezes every couple of minutes with a variable duration.
"We recommend following the troubleshooting steps below:
1. Recheck the screws of the shunt cable to make sure they are intact and there are no loose connections.
2. Reposition where the cabling is behind the power cable (ideally move the bundle somewhere else, preferably 90 degrees and see if this solves it).
3. Do you have it connected via WiFi? We noticed from the manual extract report that the signal strength was below 50%. Maybe the device is struggling and it needs to reconnect to WiFi, this is locking up the system. To fix this, potentially disconnect the device, have it forget your WiFi router and see if it then runs for a full day without any issues."
