Requirements to control heating with HA and plugwise

I’m looking to buy a house for the first time, and I want to use the opportunity to make the heating smarter.

I don’t know anything yet about the heating system, but I’m assuming I can control it.

I want to use plugwise hardware, but I’m struggling to understand what’s needed. I want to have a thermostat in the living room (Lisa or Anna), and knobs on radiators (Tom) to control the temp in other rooms.

I know that Adam and Anna come with the smile T gateway to connect to the boiler. Is HA with for example Anna and a few Toms enough, or do I need an Adam?

Many thanks!
