Hi,
I would like to use Shelly to open a door with an (old) intercom where disponible supply is only 18 volts.
Exists a Shelly compatible with that input?

Thank you!
Indeed - the Shelly UNI has (two) dry contacts. But the maximum current of each contact is 100mA; max. voltage is 36V if contact is open. Please keep this in mind!
