Energy peaks each morning (+), and evening (-)

[GM80 (Dennis Mertens)]

All,
For few months I have connected my SmartGateway to read my electricity and gas counters, successfully.
However, the electricity counters/metrics each night (when the sun goes down) turn up negatively (6000+kWh), while each morning the counter starts off with a high number (6000+ kWh).

The result is that the weekly stats are okay, but I cannot see the electricity usage during the day, since the 6000+ kWh ‘usage’ changes the scale…

Is this familiar behavior? How to resolve this?
Attached a screenshot!
Any ideas would be appreciated
