I think CEDIA (The Custom Installer Trade Association) are offering this type of couse in Brighton in a couple of weeks time.
Alternatively Armour Home Electronics may offer something.
Or even come and see the Smart Home pavilion within the Home Building and Renovating Show which is at the end of this week at Excel, Docklands.
I am speaking in one of the seminars about Home Networking and Someone else is talking about Home Automation in the morning session. There is a different one in the afternoon on similar subjects.
