Shelly i3 to monitor relay state

I'm trting to use the shelly i3 to monitor the state of a relay (not IOT) , but the shelly reports always the status ON independently from the relay status.

The relay commands some bulbs and my obiective is to detect when these bulbs are ON or OFF.

I have configured the inputs as "Toggle Siwitch".

Theorically the relay is a switch and therefore the shelly i3 should be able to monitor the relay state.

Suggestions?

With which power is the relay supplied/commanded? Mains voltage or low-voltage (e.g. 12V or 24V)?

Mains voltage
