I have here two eletric meter
EasyMeter Q3DA1004 V3.04 for the house
Elster AS1440 for my exhaust air heat pump with day / night / total counter

I also have one Raspbbery Pi 3 wich I wanna to use. There is already an
total different project running (https://github.com/pi-hole/pi-hole). Is
that a problem?

What controller(?) do I need for those electric meter?
