Quinetic switches etc

whjohnson
Already fitted one of these for some LED strip in a kitchen when it was added post-kitchen-fit as an afterthought and it works well.

There is now a proposal to fit another to control a light fitting in another room. The requirement is for a stone 'feature wall' to be left uncovered so no cables down wall please - doncha just lurve these cushion throwers!

Question is, how to make the two switches in adjacent rooms not turn each others lights on? I don't recall seeing any DIP switches to swap operating frequencies on the previous switch I fitted, hence the query.

Comments welcome

    presumably the RF link budget (transmitter power, losses and minimum detectable signal) was very close to failure when first installed, and addition of lossy furniture or decor chopped of a few dB off the signal strength, or an new source of interference raised the noise floor a bit,  and put it into  the more unreliable than not region.

    I often think simple  radio links like this need a way to indicate signal to noise ratio or link budget margin  before it gets critical On a real comms system you like plenty in hand, like a factor of ten or so, or it will be intermittent eventually.
