I have recently switched to an electricity provider that gives free electricity between 11am and 2pm. I’ve set up my ESS to fully charge the battery during that time (or come as close to it as possible), and my EVCS to charge the car at 32 amps (230 volts, or about 7.3 kW) as well.
What I would like to do is customise the EVCS so that outside of that window, it will also do automatic charging if there’s excess solar. I can do this using modbus - I’ve played around with it enough that I know in broad terms what to do (and I can look up the specific details of which registers to adjust, and what values to set them to, very easily) - but I would like to do it “natively” if possible - ie, have a schedule outside of that specific window that tells the charger to go into auto mode, rather than setting a specific current.
Is there any way to do this through the native web GUI, or do I have to get off my butt and finish setting up a bunch of equipment (mostly a Raspberry Pi, if I’m being honest) to drive all of this behind the scenes? (Yes, I’m lazy. Yes, it’s been on the agenda for a couple of years now…)
