In the Fox Cloud 2.0 app, I set up a manual schedule as an experiment to see if I could figure them out. I now can't delete the schedule. (It's turned off, it just remains in the screen of schedules).

On the manual scheduler page, if I swipe left on the schedule I want to delete, the Delete button appears. I select Delete, the schedule disappears. But then, no matter what I do next, the schedule is back next time I open the page. I have tried hitting Submit after deleting it but get an error message (Code 40257 Parameters do not meet expectations. Please reenter). Hitting Back, swiping down to refresh the page, even quitting the app direct from that page, none of these work. Whatever I try, the schedule is back next time I open the app.

Is this a known issue where deleting schedules doesn't work? Or am I doing something wrong?

I have heard of this happening before and recall they ended up leaving it in the schedule in but having it set to off so that it was ignored - I don't recall the fix but would suggest you try deleting it from the foxcloud.com website and if that fails, it may well be a firmware issue.

Can you check you firmware versions - in the app, click Device, Inverter then click on the serial number under the image of the inverter and post here your Master and ARM versions and i'll check the latest for you.

Master - 1.33
ARM - 1.49

Thanks. Kind of hope it is up to date, as I'm one of those whose installers don't do aftercare, and the last twice I've contacted Fox in the app, both in May 2025, one is still Processing (i.e. they're never going to look at it) and one they just closed with no response or change!

They are not too far behind Master 1.40, Manager(ARM) 1.56 is the latest.

Can you post an image of the schedules you have set and highlight the one that is to be deleted please.

Thanks. Have asked for the update, in fairness they did do the last firmware update I asked for about 6 months ago. First time attaching an image so hopefully it's worked.
