Does anyone know if it possible to get Emoncms to record whether a no voltage switch is open or closed.
I have the RJ45 breakout board and have a few inputs ‘spare’ so was curious if I could log the state of certain switches.
Does anyone have any suggestions?
Do you mean, detect the state of a switch that is de-energised upstream?
If so, what sort of switch?
Are there other switches and loads fed from the same de-energised point?
Are there any other disconnects between this switch and a load?
