Can't see why it would trip based on the app. You can turn off IO completely in the app.I noticed that the Tesla app now shows charging history, so it sounds like something has changed. Let's see what happens but thanks for the comment. Fingers crossed it gets fixed as it's a bit of a lottery at the moment as to whether my car charges or not. Something is causing my pen fault device to trip and I can only imagine the Octopus app is doing something that trips it out.
if your charger supports scheduling, just temporarily set it to cover the 23:30-5:30 slot as a short term workaound.
