BJM188 Are you still seeing a 300-400 W draw or so?
@KristianS experienced the same, and based on the feedback, we have introduced the "Eco off during hold" toggle in the Advanced section.
So you may want to toggle than on, to get a true Hold.
We may explore Pause/Unpause functionality for it instead, but this isn't supported on the Gen1 inverters, so we'd rather have an option that works across the board, rather than segment it into differen "if then else" statements and make things more brittle.
