Hi Michael, Now that the battery cell polling is working reliably for my Gen2 Leaf I am interested in using the Battery/Temp Monitor Android feature you have for the Twizy. I have got stuck however trying to setup the Android build environment in Android Studio. I have installed the SDK for Pie v28, and included a gradle.properties file with android.useAndroidX=true to resolve the build error on AndroidX dependencies. I now seem to be coming up against build errors for older packages such as: error: package android.support.v7.app does not exist error: package android.support.v4.content does not exist A google on these types of errors suggests updating implementation and import statements to AndroidX equivalents, however I assume it is simply I am missing an option somewhere to have these packages downloaded and included in the build? Apologies if I am missing something simple here but I could not find a guide similar to that for building the open vehicle monitoring system environment. Thanks for the help. Cheers Derek
