So, I've moved into a new home and in our hall we have 3 lights all powered by any of 4 light switches which are positioned at various points along the hallway. They are all on a relay circuit, the switches are the 'trigger' type rather than on/off - and they trigger a relay in our storage room to turn all 3 lights on/off.
What I wanted to do was to use one of these:
http://www.uk-automation.co.uk/products/Green%2di-Single-Gang-PIR-Dimmer-Switch.html
It's a single dimmer switch which detects movement & light. If movement is detected and the light is below a configured level, it'll fade the lights in to a configured level for a configured time. After a time with no movement it'll fade the lights out again.
This is perfect for my needs (entering the home with the pram and holding bags of shopping it's very hard sometimes to turn the lights on!), however because the light switches are on a relay circuit, I am assuming that this will not work, firstly because the light switches are probably not on the same circuit as the lights (so wouldn't be able to dim) and also because the light switches don't have on/off states - they are simply triggers. As I'm sure you can tell, I'm a bit of a newbie when it comes to electronics.
My question is - is there a way that I can make this work, and if so - what will I need to do?
