At present, all the sockets / lighting / garage doors / blinds and basically anything that can react to a contact relay or dimming circuit is handled by custom designed PCB's built from the ground up using PIC controllers. Very cheap to make and totally customisable, relitive to the 'off the shelf' kit.

Its first pass, and at the moment its driven by a single back end database which uses rs232 to drive all the modules via a custom app.

This database is then front ended with a pretty web front end which will be designed to run on PDA's and the growing numbers of internet tablets, including the likes of the Ipad. Everything runs through the database, giving unlimited multi-user / multi-interface opurtunities.

The goal was total integration, so temperature inputs will be present in the rooms, ventilation system, solar heating and outside along with sunlight sensors and trending patterns to run the heating / ventilation / blinds / smart glass at the optimum setting to keep the house comfortable at minimal cost.

All power circuits will be categorised for purpose and monitored for current drain, and this is turn can be used with home / away settings to reduce power consumption in unoccupied rooms. Each socket can be switched to UPS for resilience, or off for safety, as required.

Input boards take care of light switches, heating controls etc and can be simple contact switches or smarter capacitive touch screen glass with vibration feedback, which we've also custom built.

Bit masked cctv replaces pir's in wide coverage areas to ensure auto lighting isnt triggered falsely and improve accuracy.

Multimedia is on the agenda, but most of the hdmi matrix / Cat 5/6 baluns I was looking at were only hdmi 1.3, and 3D has pushed us up to 1.4, so might need a rethink there. Storage isnt an issue as I'm a data storage consultant by trade, and media will likely be delivered via Windows Media Center as I've known it for years and it goes from strength to strength.

So, automation, but with integration and efficiency as the key goal, but at a very affordable price.... (to me anyway )
