Synchronizing Data

The majority of the time when I open this app it connects to Bluetooth, and then starts synchronizing data and the synchronization never ends. While the is doing that it is not usable, it’s like it’s froze up. This has been going on for a few years now rendering the app useless.

Poor Connectivity

Cannot connect even a few feet away in the house. Apparently no way to work with Home Assistant or BT repeaters. So I was never notified of a low battery. That was the purpose.

Multi Car Uses

I have 4 of these installed on two classic cars and two electric cars. Works great. Very nice to monitor your charging system on the fly. The app need a way to rename the devices.
