Indeed you are correct. But Hive can work as boiler controls without the internet, though I would loose the weather control and other functionalities such as using the app or obtaining my gas usage on a nice chart. Nest and Wiser need the internet to work and as soon as you take it out of the box, you need to connect them to the web, making them useless if you don't have an internet connection.Ok. Just so you I know. I believe hive need the internet to be compliant for the weather analysis part.
The whole point of my post is to find smart controls that work without the internet. I don't have the internet at present,and can't have it for a while. However I still need to be able to have controls that work with my "soon to be fitted" new boiler. I don't want to buy non-smart/traditional controls now, only to change them for smart ones in 3months.
