Ev home charger scheduling issue

I have a fox home Ev charger and the app.
If I schedule a start time of 0030hrs to 0530hrs (my cheap rate times) it doesn’t work!
If I schedule it for 2355hrs to 0530hrs it does work!
So it seems like you can’t set up a schedule unless it’s for the current day, has anyone else had this issue or got any advice?

Many thanks

Just to double check that you are using ‘scheduler’ and not the charge periods.

Often it’s simple things like an overlap with another scheduled item i.e. if a previous schedule finishes at 00:30 and the next starts at 00:30 the first schedule will actually finish at 00:30:59 which can overwrite the next schedule, but if you can post images of your app scheduler settings that would help diagnose.

Which inverter is it H1 (G1/G2), KH, H3 etc.. - and what Master, Slave, ARM firmware versions are you running.

Hi Dave

Many thanks for the quick response, I have attached a couple of screen shots but to be honest I’m not sure where to find the information you are asking for!
What I can say for sure is I am using the scheduler and there is no crossover as I’m only using one!

You can get your firmware versions by on that second image (‘Device’) click on the serial number underneath the picture of the inverter and towards the bottom will be the firmware master, slave & ARM versions.

I’m wondering if the problem is that you are spanning midnight, the scheduler cannot go over midnight it’s designed to run in the current day, so for example if you wanted to go from 23:30-05:30 you would have to set 2 charge periods, 1 that ran from 23:30 to 23:59 and the second that ran from 00:00 to 05:29

Hi Dave

In actual fact the opposite is true and that’s my issue!
If I schedule for 0030hrs to 0530hrs to does NOT work, it won’t pick up the schedule.
If I set it from 2355hrs to 0530hrs it works fine!
But I want to be able to set it 0030hrs to o530hrs as these are my cheap tariff times.
