Anyone using Wonderwatt with IOG?

I’ve set up Wonderwatt for the first time today. Octopus have given me a charging slot from 23.00-08.30, and Wonderwatt has picked this up. I was expecting to see the GE Timed Charge change to match these times, but so far there has been no change from my normal 23.30-05.30 slot. I have linked them using the GE API.
Any ideas please?

Have a look at the WW forum https://community.wonderwatt.com/ in case this has already been asked.
[I'm on OF, so can't help with IOG.]

ChrisRowe Was picked up perfectly, we just issue the inverter charge instruction a min or two prior to the charge start time.
