Ratings and reviews

Works well, needs a bit more refining, but its a new app so sure its coming. When i turned off charging the app froze and I had to restart. It did stop the charging though. At first I couldnt connect, but the BT was activated from the Xioxang app which i had opened first. I restarted my phone and it connected right away. The bluetooth works from much further away than my Victron hardware, which us neat. The bluetooth power must be cranked up.

If you had the ability to put this in the background and send alerts when the battery reaches a settable low charge state, it would be utterly awesome. Yes I know you have to be within bluetooth range but that's ok. In addition being able to set/change the Bluetooth PIN is important and nobody does that -- without that ANYONE within range of a battery with this app can literally destroy it by setting BMS parameters deliberately wrong or just shutting off the FETs! ADD PIN CHANGE PLEASE!!

Edit: The app can now see my two BMSs and the app shows the version mentioned by the developer. However, it cannot connect to the devices and read data from them. I tried uninstalling and re-installing with the same result. I get the message "no connected BMS". I, too, am having the problem that others are experiencing. The app continuously scans for Bluetooth devices but never finds anything. Due to company permissions on my new phone, I can only use apps from the Google Play Store.
