Using OpenHab or IFTTT for more control

I testing a Tado radiator thermostat to operate the heating in a secondary home.

I need to be able to switch the home between "home" and "away" modes manually. I also need several "home" modes, as I only want to heat bedrooms that are needed.

I already discovered that the APP, and the Web service is not suited for what I want. So I am interested if more control can be achieved using IFTTT and/or OpenHab.

More specifically: Can I set a temperature using OpenHab? Using IFTTT?

I would then just define several "scenes", with a temperature set for each room in each scene, and switch between them as needed.

Anyone here in the community have good experience with the Tado/OpenHab integration?
