EV Charge Station Web-interface Settings - AND - Scheduled charge priority

Hi,

Quick question about accessing the settings on the EV charge station. I see that the extent of settings available varies depending on whether I use VRM/GX, VictronConnect/Bluetooth or local web-interface, with the latter providing the only means to access all settings. Does this mean that in order to be able to access the full settings remotely, I need to set up port forward etc. etc. to the local address - or is there something I'm missing here to get to those settings remotely?

Also - while I'm posting, I think the mode settings for auto and scheduled would benefit from some revisions. My use case is fairly common in that I want the charger to sit in auto to benefit from excess solar gen during the day, but then to always run a scheduled charge in off-peak rates overnight. At the moment, this requires an intervention to change the mode at the end of the day to 'scheduled' and back to auto again in the morning. In fairness, this was fairly easily remedied with a node-red flow, but it would preferable to have it handled in basic settings. The 'prioritization' of schedules is how other such chargers (MyEnergi Zappi for instance) work.

Thanks



John

Agreed would be a nice feature.


I would also love a ESS SoC percentage in schedule mode. ie a schedule/auto mode that runs until SoC hit as well as based on time criteria, even when grid connected i know off grid exists.

I'm in the middle of playing around with node-red to try and get that sort of thing working - and I'm getting there, but paid work keeps getting in the way. ;)

Your suggestion of an ESS SoC in EV schedule would helps achieve one of my objectives. It would even better if the schedule specific charge rate could also be dynamic (such as in Auto) around the grid set point of ESS - so maximising the charge rate allowing for other AC loads (in my case with little to no import).

My use case for this is as follows: Now that we are in summer; I regularly have a high house battery SoC at the end of the day. At the moment, this is used to charge the car supplementing grid at cheap rate) during its scheduled off-peak period, until the house battery reaches a lower SoC.

This misses two opportunities: 1. When the EV only needs a little top-up; this could be achieved largely from the house battery excess (if set to a lower charge rate to avoid grid use). or 2. When the car needs a lot of charge and it would be handy to be able to use the solar excess in the house battery plus a full 4hrs of off-peak grid.

What I want to ideally do is 'dump' any solar generated excess charge in the house batteries in to the car at the end of the day but before the off-peak period. For me, this is a two-hour window between 2230 (when the house generally settles to base loads) and 0030 when off-peak starts. That gives me scope to 'dump' around 8-9kw (based on both inverter limits and happy the max I could happily expect to have in house battery) in to the car.

When considering all of this - I try to forget how much times an AC-DC/DC-AC conversion has taken place and the inefficiencies.... :)
