Just tested it, and the driver seems to work somehow. Still have problem figuring out the energy consumption part.
It shows correct power and temperature at the moment, power seems to come a bit random from 4-10 times in a minute. Temperature every minute if changed from last.
The energy reported 0kWh after the meter was connected to the hub. Then after around 4-5 min when the time was 22:00 the meter reported 101,825316 MWh. It should be around 0,2kWh after 5 min with the power used in that time. Have to wait until 23:00 to read out energy again, but it seems like there is something else than just wrong divisor.
