BM2

Range is horrible. I pretty much have to stand inside my motor home to get a signal. App tells me my flooded cell batteries are low, and then later it tells me they are "good "even though a charge never occurred. I'll be switching to lithium batteries soon and it won't surprise me if I continue to get readings that are all over the place. Not at all impressed!

You're missing out if you don't have this device and app for car audio enthusiasts! It would be nice to be able to switch batteries in the app instead of doing into settings to switch. I run 2 AGM batteries and I would like to be able to see both. I do have a device on each battery. They are labeled front and back, but I can't switch easily. They should both be displayed if you have more than 1 device. Awesome work!

I use the app on iOS and it works fine. But, I installed it on Android 11 Head Unit mounted in the car and I am not able to get it work. It does not connect. :-( So for Android I would give 0 stars, but on my Apple iPhone it works just fine.

Thank you! Awesome app! Does what you expect it to do [with the hardware you purchased] and more! Good design and subtle yet impressive visual effects. Also the updating loading bar is a tad cute 🚀

Using with 4 modules. Works fine, but have to switch between modules. BM3 is supposed to work better but it's ridiculous to have to pay another $9.99 after spending $120 for the modules.

Great little app but is there any way to export the trips into a CSV or spreadsheet? Would like be access to this data in Google sheets or something. 5 stars if this were possible!

Good product, only problem does not give update on battery status unless you connect to device. Got 4 installed on my delivery vehicles but must connect to each one to see status.

Could you add possibility to save readings into external file. It is difficult to analyze pictures...

Was great originally but now when I am charging my AGM battery in my camper it only sometimes says "charging" even when I know charge is going into it and the percentage is going up..is there anyone to email to ask some questions please

Really nice update with fw v8, if you add also Li-ion, LiFePO4 profile it will be super cool. Bug. When you pick custom battery and create battery voltage profile. Percentage in main page is not corespondent with voltage table in BT settings.

So far I think the app is great and works well with an easy setup to get going. Would like to see more functionality added to the app...

Good but don't take it as gospel as not accurate especially with AGM now it is included as a battery type. Mine is showing 62%when I know it is >95% and it is a week old and coded properly.

When it connects its good, nice features ect... No real function complaints. Would like an option for 12/24 hr clock option no response from dev 1 star removed

Excellent range always handy, get a alexa socket and schedule, get notifications to keep that battery topped up! Great kit...

Has stopped working, Can not edit the batteries Can not change from main battery to spare battery. Have uninstall app and reinstall, still no luck Graeme Treacher

Great device but needs a voltage adjuster. Voltage is kinda off

Under firmware update, Current version: Vnull Broken since last update May 2022!

This needs a function to export data, which is very helpful when getting warranty replacement on a weak battery. Also, if you have multiple sensors, the app keeps changing to the sensor with the strongest bluetooth signal. It needs to stay on the chosen device until the user changes it. It would also be handy to have a quick device selection on the main screen, rather than having to go into settings to switch devices every time.

(Edited 3-9-20) There are multiple issues. First, the advice the developer keeps posting here does not keep the app from repeatedly popping up. It periodically restarts, I think maybe if it sees it's in Bluetooth range of the sensor. It can be Force Stopped in the Apps setting, but eventually it pops up again! And there's no way to remove the notification except killing the app manually. Other problems: There is no way to export the data. When the app is started, if you don't notice that it says "UnConnect" in small letters at the top, you may think the displayed status and animated voltage are real time - but they're not, they're old data until it connects.
