Nice app, would be great, if they include the current being moved around, as well. In addition to voltage being shown. Including the value of the current being moved about, would help in showing that this device is really working as claimed

Heyy... I would say very good... but having a 2x14V battery pack when I try to watch the realtime graph resized to see how balancing works, it is impossible, as after the resize at the next refresh, the graph is normalized to have 0 in middle. Anyway, would be nice to have some description of the protocol used, so I could build an addon for Home Assistant.

Installed it worked at night for a few hours, but in the morning, it didn't connect anymore, I cleared cache, date, installed app on 2 cell phones, it didn't connect more Bluetooth. I don't know if Black Box is working because it lost Bluetooth connection even trying to connect 5 cm away.

No connect to phone Bluetooth Each time I try it says "Pairing rejected". I have tried unplugging the black box for minutes and still it will not connect and the app interface is just empty.

App no longer works on android phone. Have uninstalled and reinstalled App twice without improvement. App only shows white screen with no battery detail. Even at 1 meter from battery balancer no response. Swipe down on screen indicates refreshing but white screen remains. Restarted phone but still no improvement. Had already previously disconnected battery balancer from batteries for 30 minutes and batteries are both at charge of 13 to 14V each so these proposals by developer are not applicable.
