Here is my dilema:
I started logging to my influxdb2 a while after my power meeters were already running.
Because of that I am currently missing the initial value of “0” kWh in my database which I need for my grafana calcualtions.
So I need to write that value of “0” to my influxdb 2 database, the easiest way for this seems to be the “line protocoll” but I cant figure it out. 
I need to write to: [_measurement"] == “actual”[“_field”] == “E_Grid_Exported”
the _value = 0
with the _time set to 2023-01-01 00:00:00
Can anyone help me with this please?
