No voltage on O I ouputs on shelly1

Hi all.
i have Shelly 1, i connected it to 12V power supply, move the jumper and add a light source (12V 20W) on the O I outputs.
i manage to supply the device with 12V, than i connect to the web interface, when i flip the switch im hearing a click sound ( i thing this is the relay ) im seeing on the web interface that blue circle around power button lights up, but the light source is not turning on.
i also click a few times the power button that is in the web interface, hearing clicking sounds again but still nothing.

than i get my multimeter and put the probes on O I and i did not get any readings.

i connect the light source directly to the power supply and it lights up but when is connected to the O I pins it does not.

Could someone help

Welcome to the forum!

The relay contact of Shelly 1 (between terminal I and O) is a „dry“ contact! Hence, you’ll have to wire terminal I to +12V, one leg of the lamp to terminal O and the remaining leg of the lamp to -12V/GND. Have a look at the ‚lexicon‘ to find more diagrams!

Hi.
Thanx for response.

Do you mean this diagram ?[Blockierte Grafik: https://smarthome-forum.eu/index.php?media/195-ar768-ausschaltung-png/]


Cause i currently use this one

If you alter the (first) diagram found in lexicon mentally from mains supply to 12V DC supply (N equals +12V DC, L equals GND), you may use it! The second diagram describes the implementation of a potential-free („dry“) contact in an unknown environment - nobody knows where the two green wires are leading…

Thus, adopting my tales in post #2 with terminals I and O to second diagram, it is applicable.

Thank you.

I manage to make the connections.

Now when i flip the switch ON, im hearing how the relay is clicking repeatedly without stopping and the light is still not turning on.
