Currently working out a plan for fitting a C-Bus system to my house, initally for lighting. It's been a standard for decades. It's expandable and future proof. It's the only way.
I watched a programme last month about an air crash of a Korean plane that happened because the copilot simply didn't dare to overrule the pilot, even though it meant the death of everyone on board including himself. Grim.
2K? Paradise. If we wanted 2K we had to wake up in middle oft night, 2 hours before we went to bed, and lick road clean wit tongue. Then we'd come home and the BOFH would murder us and dance on our graves for tuppence a lifetime. And so on.
