    I'm asking out of curiosity. After the March update of the Dr. Prius app, it stopped connecting to my NHW11. Do you happen to have a similar problem? I've tried both the cheap Vbox OBD2 reader and the more expensive Veepeak, and the same problem persists.

    Yeah, you have to download an older version of the app. I did not dive too deeply but I simply uninstalled the latest version, googled "dr prius apk", and downloaded whichever CNET had available since its a trustworthy source, at least it was growing up lol

    I've never gotten Dr. Prius to work with my G1s. I assumed it didn't because of our old com protocol. All it does is show the demo app and, I forget exactly, but it showed some rudimentary data, but nothing useful for understanding battery health.

    Am I doing something wrong? What data does it provide for y'all.

    Thanks. In fact, after installing the older version it started working. In my case ver. 6.59

    Dr. Prius won't show anything beyond basic data for the NHW11. You can only partially verify the battery yourself by measuring the Delta SOC and Volt diff parameters, as well as the internal cell resistance.
