3 stars: I bought one of these from Autozone for my house generator battery, after the gen set failed to start during a power outage and I learned that the battery died. Setup on Android was very difficult. Please put in the instructions to shut down mobile data before using the app. Once I learned that, the device setup was not a problem. But you owe me 20 minutes of trying to set this up before I learned the trick from reviewers here.
4 stars: Not too bad. Make sure you turn off mobile data before starting, then set up. App refreshes every 10 mins, kinda threw me off because I thought it wasn't working and kept running setup again. Just wait, eventually the battery will show up. Only thing I don't like is that it has to be connected to WiFi to work, not sure why, once it is set up, I can't check status on 4g? Kinda goofy. Otherwise, seems to be working ok.
5 stars: Excellent wireless battery monitor device. Agree 100 percent with the long Sept. 20, 2017 review by Google user Vinny Pinto. Pain in the butt to set up the first one or two monitor devices becauz of flaky instructions and quirky app. But once you get the hang of setting up the monitor(s) initially, it is easy. They are very reliable once set up. Work very well. I use this app on two Android tablets w/large screens. Also on one Android phone. All work well, at home and when traveling.
5 stars: Download the app, register your account with the app. Sign in to the app. Immediately turn off mobile...
