What Tado equipment do I need?

Options

Hello all,

I'm hoping to switch over from a Nest v2 setup to Tado in the coming months, So have a question about what equipment I need. Details on my current setup below:

New build, brand-new heating system (2015).

Two zones in the house, upstairs and downstairs, can be controlled independently.

Downstairs, controlled by a Nest v2 (heating and hot water), formally used to be controlled by a Danfoss TP9000.

Upstairs only controls the heating and uses a Danfoss TP4000.

Ideally, I'm looking to have TRV's in every room and be able to control upstairs / downstairs independently as it is now.

Any insight into what Starter pack and extras I will need for this setup would be appreciated. If you require more information, I'm happy to provide it.

Thanks!
