I would like to use Node Red to program my Multiplus II-GX so that the max inverter power can be controlled by
(i) time of day (so that the dishwasher does not deplete the battery and the fan does not run at night) and
(ii) battery voltage (so big loads do not take it below the 47.0 volt cut-off limit).
Has anyone done this before? If not, where do I start (I have no prior knowledge of setting up Node Red flows)? Is there a Victron sandbox where I can try out ideas without risk of crashing a live system?
