Minor Description
My colleague Fabian asked for support for these devices a while ago: https://jira.observium.org/browse/OBS-2598
I have (hopefully) figured out how to add it by myself. As mentioned by Fabian the 8310 devices were already supported. I have oriented myself exactly to the implementation of these devices.
Please note that I have also used a kinda new sensor type called "energy" to display the Watt hours. This was added by me previously, see https://jira.observium.org/browse/OBS-1945
Mike removed the support for it afterwards and wanted to add it later, but that never happened. So i just added it again for my install and it works fine for our setup since 2016...
