Is this possible to use?

The value on active power import wrong here, this happens every 10 sec i think.
Here is the hourly consumption, but I haven't got any values yet on the latest version you uploaded. Looks like there is a comma missing here too
Move the decimals 2 places, then it ok :) sould be 4502W
Still the same, but im going to the cabin now, so i will take a check directly on the meterdispaly when i get there.
I have opened the HAN-port on my meter (KAIFA) but do not get any data into Home Assistant. Would think it needs to be rewritten in order to make this work since there is a difference in the data from Kamstrup and Kaifa.
I've logged some data from the meter. This is list 1 (comes every 2 sec) and list 2 (comes every 10 sec). list 3 comes every hour, so I'll try to get it logged as well.
