Perhaps I am mistaken, but I believe Dave meant that you take the relay output from the RC and wire it back into a digital input on the RC; Setting the relay output so that it is not what the default is.

That way when the problem occurs you can see that the digital input is showing the value of the default relay output, rather than what you set the relay output to be.

(the concept is what I'm trying to clarify, maybe you can use other ports, like digital out to digital in)

Sorry if I have misinterpreted you Dave.
