greenfield project: what to buy?

[pocock]

I'm about to get started with home automation. First goal is the central heating system. It is a hydronic system, wall mounted radiators in every room and a gas boiler.

If you were starting from scratch today and wanted to buy the products that are easiest to use with Domoticz and other free software solutions:

- which TRV would you buy for the radiators, in particular, for compatibility with the software and for compatibility with the valve bodies?

- which other products and brands would you choose, for example, temperature sensors, occupancy sensors, managed power outlets?

- which network protocol would you prefer, or does it matter?

- any other comments?
