Hi,In the kitchen/open plan living area, I'm planning on 7 circuits, so 7 in-line dimmers.Is it possible to put them all in one of the kitchen wall cabinets, for future access, in case 10 years down the line they need a battery change.Would they interfere with each other if they are placed together?What is the plan for circa 10 years time when they run out of battery?Thanks,Raj
