Dead battery doesn't show up
The tracker with low battery (blinking constantly but still connected) doesn't show battery indicator in the server GUI. If put on charge it will show 100% and charging, but when unplugged the battery icon will just disappear along with percentage and voltage. Not sure if it's GUI, Server or firmware problem...
Having a similar issue where a device with 0% battery but still active will not show the battery in gui I think the tracker should explicitly say it does not have a battery rather than the server/gui guessing.. same for charge status, since it is checking for a high voltage near 5V
The tracker sends battery level either way, the problem is in the gui or server.
