AI seem to have a strange problem.
I use a youless energy monitor connected to the energy meter with p1 connection. It runs custom firmware to update used power to pvoutput. It writes the v3 parameter.
This worked accurate before i had solar as far as i can tell for almost a year.
Solar system is solaredge and pvoutput uses the api to get the solar data from the solaredge monitoring.
Now we have solar i found a issue:
Power from grid after 12:00 am (noon) is not added to energy used for remaining day.
if i export the data to excel, is see that counter for energy used is updated when power from the grid is used (in numbers)
But after 12:00 am (noon) this (energy used) filed is reset to 0 and no matter how much energy from the grid is used after that, it gets never raised again.
Image to explain it:
So from 00:00 the graph energy used is going up till about 0600
At 0600 the solar starts up.
Around 09:00 you see some extra use, and the grapf raises a bit.
Than we have enough solar to cover the day use,
After 18:00 the evening power from grid is not added to energy used at all.
