Water usage with FGBS-222 and Gianola

Hello,
I have a Gianola water meter and bought a Fibaro FGBS-222, and a power adapter.
Would you know how to do the wiring? I guess it’ll be fine but if someone know, I’d appreciate to do it safely without risking to burn it :slight_smile:

But, what is more interesting; would anyone here have experienced it already and could share how to best use it in Home Assistante,

Kind regards,
David
