    Why are there two app’s in the android app store? There is the WattCycle App, and The BMS Meta App by zhouyuanfei. What is the correct app to use? Why are there two apps? Thank you.

    As others have asked, how do you change centigrade to Fahrenheit for battery temperatures??? Not all of us live in China thanks, Steve.

    Please provide a password to set my own parameters for the Battery 12V 100AH Smart

    Would love to see your BLUETOOTH equipped battery communicate with VICTRON ecosystem.
    It would be a huge selling point!
    Please make it happen.

    This app is as flaky as all get out. I have 8 batteries. The BMS Meta one is completely broken, and the Wattcycle BMS takes several attempts to get it to show data on the screen. Out of the 8 batteries, I have ONE battery that won’t put ANY data up on the app whatsoever.
    I’ve tried two phones, both with the same results. (Both are Samsung A54.)
