Connecting smart meter to HA

Hello,
i’m looking forward to switch to HA from my ioBroker installation.
Right now I have a scenario like this: Main ioBroker running in VM and an second installation running on an Raspi 2b just to connect the smart meters(i have two smart meters that are read over IR SML2). Raspi and VM are on the same LAN.
What would be the best way to keep this configuration up and running in HA?
Is it possible to to connect to HA instances?
