Is this happening on both switches?


Can you hear the relays clicking?

Dumb question here. Have you got power connected into the relays?

Relays clicking is a good sign - that suggests that the Robbe Duo board is working in relation to being powered and receiving the signal from the RX.

I am sure you know that effectively each "switch" is made up of 2 parts (seperate circuits) - the middle man seperating the 2 electrically but also joining the 2 physiically is the relay.

Can you desribe what you have on the relay side - cable connected from and to, power supplied from , switching lights, sound, pump etc and we maybe able to point to in the right direction as to a fix...

May be a pic would help...

Bill,

Pleased you solved the problem

We have all been there at one time or another!

I once went to replace the power supply in a computer - as I came to remove the "dead" item someone had added an "on/off " switch on the back of the case that I swear was never there - a simple click and the "dead" power supply amazingly came back to life.... I am amazed that I did not spot it, how it got switched off in the first place I will never know...

To this day I have the new replacement power supply, never fitted, smiling at me from it's place on a shelf in my den...
