@newbuilder interesting that you have the LUX set from 20:30 to 23:59 then a second time of 00:00 to 01:30... I have mine set to 20:30 to 01:30.  I run a Pi to decide if I need charge or not so not the same configuration but did you find it did not work with just a single time slot?

I had the same issue, solved in the same way where I have one slot until 23:59 and a 2nd one starting at 00:00. I can't remember the exact reasoning but it was one of a) battery stopped charging at 00:00 or b) battery never went out of ac charge mode at 01:30.

@newbuilder interesting that you can have the LUX set from 20:30 to 23:59 then a second time of 00:00 to 01:30... I have mine set to 20:30 to 01:30.  I run a Pi to decide if I need charge or not so not the same configuration but did you find it did not work with just a single time slot?

As mentioned above it did not like the move over to a new day. I have the hybrid if that makes a difference.

I see it as basic coding where the new day starts at a lower number so the Lux doesn’t know what to do

If I remember they program a stop at midnight. But that was a year ago it happened to me

I have a single AC charge period from 20:30 to 01:30 and it works fine so maybe it was a coding error that has been corrected in a firmware update?

I wonder why you guys all do 20:30 -01:30 @5.5p?

I find my batteries charge to 95% flat to full in my 3 hours (20:30-23:30) at 4.5p, so surely all of yours will too?

Or is it your EV' s that need the extra 2 hours?

Because that is my off peak for charging car.  I believe that the system also balances according to the strain on the incoming AC. So I want to give it as long as is necessary. Also if you force charge it will not use it whilst off peak is running.

I'm on intelligent octopus, my charging actually starts at 11:30pm. 
If i get some additional 5p slots outside of the 6 hour window i'll charge in advance (e.g. if 7-7:30 is 5p and back to standard rate at 7:30 to 11:30, i'll charge up 7-7:30 so i can live off of battery for a little longer of standard time).

I have a Mk 1 Leaf that only has a 3.3kW on board charger so I need five hours to get a decent amount of charge in on the cheap rate.

I went for the 20:30 start because it lets me run things like the dishwasher and tumble dryer before I go to bed on the cheap rate too (they have no smart functionality and I don't trust them not to burn the house down overnight!)

How do you get a 4.5p or 5.5p period? Mine has been at least 30p all night lately.
