Hi,
Can anyone tell me please if Shelly Uni can have input from a dry contact (zero voltage) sensor which is normally closed ?
All I need is to fire a Smartthings event when this event occurs.

Welcome to the forum!
Yes, both digital inputs (IN-1, IN-2) of Shelly UNI may be controlled by dry contacts. One side of the contact must be wired with pin ‘SENS Vcc’, the other with the appropriate input (IN-1 or IN-2).

Thank you for the welcome and thank you even more for the answer! That's what I was hoping. So I'd wire it like this diagram I suppose?

I'd just need to trial and error which the COM and NC out of my sensor go to on the Shelly
It would be more convenient and reliable to use the SENS Vcc pin (4) for the high side of the contacts, as I mentioned above.

Ahh yes, I see which you mean! Vcc_sensor. Great! I've just ordered my first shelly thanks to your help
