I set a force discharge each evening, with FD cutoff at 15% so I have 5% left to use which sees me into the cheap rate window. However, instead of reverting to battery use at the end of this schedule, I am pulling from grid. This seemed to change when I was upgraded to 1.09 as it worked as intended previously. Having had a further upgrade today by my installer, the issue still persists.
I am in contact with Fox head office tech support, who are not aware of this problem, and tell me firmware logic hasn't changed.
If anyone experiencing the same could reply to this thread with your firmware versions, it may help them track down the problem.
Many thanks

If at the end of your schedule, the battery is too cold, then it will pull from the grid to maintain a certain min temperature.
So make sure to read your battery temperature at this time to rule this out.

Yes noted, but I dont think this is the issue
As long as you test this later, then as said it rules it out.
Just to clarify for myself and others.
It worked when it the BMS was below v1.009 (typo in above 1.09)
Stopped working correctly when upgraded to v1.009
And error remains on v1.011
It is an issue that has been extensively reported by users in

Should be pretty easy to fix:
If 'Force Discharge selected' AND time is between 'Start' and 'End' time AND "SOC>FDSOC", proceed to use 'Force Discharge', otherwise revert to 'Self Use' mode.
But for some reason Fox thinks it is "otherwise revert to import from grid".
It has been reported that mode scheduler is getting an upgrade in Jan/Feb this year so hopefully it will get fixed when this gets released. The issue is definitely holding back recommendations for the Fox Brand in Australia.

Confirming I am also having this issue. Feb 2026. FoxCloud 2.0 Android App.
I still have this issue with my kh10/ep11 setup.
As it's getting sunny now in the UK, this is a real problem as forced discharge can't be relied upon to return to self use when the FD soc is met.
Has anyone heard of a fix to this yet ? Other than to start using home assistant....

I logged a support ticket with FoxESS more than a week ago but not had a reply. Very poor support.
I have just discovered this issue also and have emailed UK support as their online support ticket errors at the captcha
Do they realise how massive a problem this is??!!? There is literally no point in having a peak time discharge schedule if it doesnt revert to self use when the SOC is reached. Because during this period any saving you are making is more than being cancelled out by the input grid premium tariff
They need to fix it urgently
