Avenir Thank you - looks like the old way of enabling eco mode and AC charge upper limit (set at 15%) using the presets messed this up.
We also noticed an issue where we weren't always sending AC charge upper limit as part of a charge slot using the new settings mechanism. This will be fixed and rolled out in the next 30 mins.
Apologies for the inconvenience!
Update: fix available, v0.3.329
