Hi - I recently installed 6 single gang Quinetic in-Line receiver switches (QURS1W) and paired them successfully with multiple Quinetic wireless switches - I have unpaired 2 of the switches and they are no longer working - the in-line switches themselves have stopped switching the circuit and I cannot pair any further wireless switches - it is as if the switches have died. I have seen on other forums that this has happened elsewhere but no solution offered - does anyone have any advice. Many thanks
