Hi Pete,
I need the same configuration.
I haven't bought yet but I'm thinking of openHAB on a raspberry with FS20 R=
F thermostates (Conrad).
Maybe I start with an FS20 controller but I like the flexibility of openHAB=
.
In the end I want to control my complete energy useage with my smartphone.
With openHAB I can do that.=20
