No output voltage

    I have wired up a new Plus1according to the Fig 2 in the user manual, with a 12vDC input going to 12v, and GND going to both SW and GND on the Shelly. I can control it via the app over wifi etc, and the relay "clicks" in the usual manner.

    BUT, putting a multimeter across the 0 & 1 outputs no 12vDC output happens, and I can't work out why. _Sometimes_ a _very_ brief and _very_ small voltage is detected when I activate the app, but I think that this may just be "noise".

    I have tried changing the Settings / Input Output / Relay Type etc, but no combinations cause the multimeter to register an output voltage.

    Any ideas gratefully received,

    TIA

    Pins I and O are connected internally with a “dry” contact of Shelly’s relay. Thus, it is quite normal that no voltage can be measured between I and O. You’ll have to connect supply voltage to pin I and the load to pin O. Other end of the load with common/GND.
