Thanks!
The inverter push setting is dayenergy=1 so I’ve left that as is.
The meter push was also dayenergy=1, so I’ve changed that to auto=1
See what happens later today.
Live chart seems to be behaving better today. 
The post appears to be over a year old. Has it been fixed? I only have a a few days, but it looks like this is still the case, 24:00 (00:00) data is missing and 00:05 always starts with 0W consumption. Maybe I’m missing something in the setup.
Recording the last 5-minutes of the previous day via Fronius Log Push will be a future enhancement.
