Hi,
I am using a uni to control a front gate with a dry contact. The gate works fine when a regular manual switch is connected. When I connect the uni up to it and switch it via the app the gate just buzzes but does not always open. The gate is on its own power source from the shelly and has 12 volts coming in...yet when measuring the power going into the gate it is showing about 7 volts. The power 12v has the positive to the gate, and the negative traverses the shelly uni .. so the shelly is switching ..just doesn't seem to be getting the voltage through to open the gate.
Does anyone have any thoughts on why the voltage is dropping ?
Appreciate your help and thank you in advance.
