With my end user hat on instead of my techie hat it doesn't really matter to me why I can't do it - the point is controlling Evohome via Echo has these limitations, regardless of whether it's Honeywell or Amazon to blame.

It's early days so hopefully things will improve, but at the moment I find it more inconvenient and limited to use than just using my iPhone, which is normally never far away, or the controller which is a short distance from any downstairs room due to its central location.
