Just an observation really. One of the nice things about Idratek is that the modules give state feedback, but I was thinking that the ones with changeover relays could be improved by signalling not only which output was switched to connect to the input, but also whether the result was a live circuit. You could achieve this with the existing modules by putting a relay in series with the input, which could switch a detection circuit connected to an Idratek input. Achieving this in a fashion that would meet Electrical regulations might be rather challenging though.
One use for this occurred to me when considering lighting switched using a traveller or multiway system. With a two-way traveller system there is no simple on position of the switch as this depends on the state of the other switch. Hence system state cannot be inferred from the switch position. If both switches' states are known, there is no problem, but if only one is known then it is not possible to say whether the light is on or off. Another example is where the Idratek power relay is fed though a switched spur (not an uncommon arrangement) where it is possible the power to the spur might be off. In both of these cases it would be helpful to know if the result of activating the relay was a live circuit or not.
