very frustrating. Not Working on Pixel 7 or older android phones with android 12 or Samsung tab no chance. Says allways no version avaible for your smartphone.......

BMS only connects once, can't disconnect and reconnect unless BMS is power cycled and app is closed & restarted.

App show wrong temperature. Old "original" app show temp right. I think this app show bms fet temp or something similar. It is always too warm. So it is not show actual cells temp like original old app. Example i take my battery outside of my house for half hour, and in old app temp was +16.2c and this app show still +29c. And when battery is outside like 12h below zero temperature, your app show +26 and old app show almost zero.

So i in this state you only monitor some other temp sensor than that one which is located to cells. Example many bt bms has actual Fet / Mos temp, Balance temp and one or more actual cell temps. And fet/mos or balance is always much higher than cells.

There is picture of old app when battery has been outside of my house for 30 min (at -2c temp)

and there is screenshot for your app at same time as picture above. See big difference in temp readings.
