Another one of our devices has stopped transmitting data. It worked fine until two days ago. In the diagnostic dashboard it says "Device Never Registered" which is wrong because the device was working fine and has previously registered. I see it sending data until a day ago but nothing since. It should be sending data every 6 hrs. NOTE I also created another post for another issue with a different device. Al together we have 20 or so devices and except for these two others are working ok.
