Bluetooth distance is short

The device actually connected easily and works quite well. My problem is I have to be very close to the car for it to connect to the Bluetooth. Not sure if this is this particular apps Ben issue or if it is just how Bluetooth is.

No lithium

There should be better support for lithium batteries

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.

CarPlay App or Widget would be great

CarPlay App or Widget would be great

Lescars

Leider funktioniert die App nicht mehr mit den neuen Wächtern von lescars, wurde irgendetwas geändert?

Traveller

I have 1 battery for driving and 2 (classed as 1 as it is linked) for RV life…..BUT I CAN NOT VIEW BOTH BATTERIES AT THE SAME TIME !!!
Frustrating !

Keine Verbindung

Seid IOS26 verbindet sich Gerät nicht mehr mit Handy…

Need more settings

I have a question about low limit measurement voltage level. Now is the range from 9-15 only. The input voltage is from 6V. is it automatically range, when lower values will occur? It is possible set lower limit (2V) by customer in next version ?

App打不開

已經好幾年用IOS系統都打不開APP了,是停用了嗎?

Good monitoring app

Been using this for several years and works as expected on an iPhone 13

Jest okej

Spoko aplikacja, czysto i przejrzyście. Po pol roku uzytkowania nie doswiadczylem zadnych bug-ów czy czegokolwiek.

To JohnTheReed

I’ve had BM2 on my Niro EV for three years and never had a problem with battery drain on the still OEM battery. I think you are right to question the dealer who squawks a miliAmp draw.

Trochę mało rozbudowana, tylko podstawowe rzeczy są.

Issues with multiple vehicles.

Have used this app for almost a year and quite appreciate it’s usefulness, but have a real issue trying to switch screens between installed hardware in different vehicles. I installed the sensor unit in two vehicles but cannot seem to get the app to switch between them.

Bluetooth

Le Bluetooth ne fonctionne pas déconnecté.une mise à jour du logiciel est nécessaire au plus vite. Merci

Нужен экспорт данных

Хорошее приложение, наглядно показывает урони заряда АКБ.
Просьба сделать возможность экспорта данных в виде файла для анализа на компьютере

Nicht für LiFePo

Laut Beschreibung auch für PV Anlagen, aber es funktioniert nicht. Man kann die Batterie Zustände zwar einstellen, aber die App zeigt dennoch nur Werte für Bleiakkus an.

Doesn’t do what it shows

I wanted an app specifically for the percentage of battery. The screen shots show it, but the actual app doesn’t. This is the only thing I bought the Bluetooth monitor for!! I wrote an email / contacted app support and got no reply. Not impressed.
