Slave EVSE not returning to normal mode after Solar mode was active

[djoenez]

My skoda does not want to play nice with solar mode if there are alot of clouds (so the charging gets started and stopped a couple of times) So i just want to put it in normal mode but a low charging current to fix this during cloudy days.

unfortunately when i had both my chargers on solar, switch master to Off (only want to charge my slave) and switch slave to normal i still have the status: Waiting for solar. and if reboot the EVSE, it will default to solar again.

Could you post the settings of both EVSEs?

What happens if you put both on Solar, switch Slave to Normal, and then switch Master to Off?

Hello Dingo, will do asap, unfortunately i will not be home with 2 cars for the next two weeks, will update ASAP (thanks for looking into this!).

Just a question for my understanding: Is it possible to use the EVSE2 (smart or solar) when master is in off mode? or is this prohibited?

Maybe also a feature request: I ask these questions because sometimes i have two cars connected but i want to charge one car in particular of solar (and only start charging the second car when i have enough solar power, i have enough to charge 1x16A + 1x8A for example). But now i don't have this choice, is there a way to "toggle" the preferred car? Or when the car is connected to have a toggle which states you may charge (so you prevent it to charge even when the selected mode is solar?)

The "OFF"mode is actually setting the Access bit off; so this is the same as when you have RFID reader activated and you would not identify yourself with a valid RFID card.

So I would expect the original firmware to be able to charge on EVSE2 when EVSE1 is not used/no RFID card is presented; and I would expect the serkri firmware to do the same, since we did not (intentionally) change that behaviour.

But I only have 1 EVSE so I cannot test it for you....

I understand your feature request, makes a lot of sense; for the near future I would use HomeAssistant and the ha-smartevse integration to script this kind of behaviour. I intend to start using solar mode this summer (also through HomeAssistant) and when I have some practical experience I might either publish my HA automations OR build them into the SmartEVSE firmware....

@djoenez could you please test this with newest release 1.6.0 and, if problem still exists, post the verbose telnet/debug log here?

[djoenez]

@dingo35, will do. Just got back from long work related travel, as soon as i use the second car again i will update this thread with testing. Thanks!

[djoenez]

Works now as expected. Thanks for the fix!
