    Hello.
    Is the NO/NC connector of a wifi relay for example such:

    Control of 12V voltage via NO/NC connector of WiFi relay in SmartHome system .
    Control of 12V voltage via NO/NC connector of WiFi relay in SmartHome system .

    It is possible to supply 12 volts and then this connector can be used to voltage control other devices, or can such a connector only be a voltage free connector?
    Thanks in advance for your help, as I would like to use this relay to control a 12 V air freshener in a SmartHome system.

    The relay has a contact current capacity of 10 A at 250 V AC. Consequently, it can make a contact of some device, or switch the power supply on and off. ;) This is probably what the author had in mind?

    You can apply 12 V to the contacts to control the switching on or off of, for example, a light bulb.
    The current capacity of the contacts when supplied with DC is 10A at 30V.

    It depends whether it's a voltage-free contact or a voltage contact.
    What does it look like?
    What kind of kit is it?

    Since it has 3 terminals inserted, these are definitely voltage-free contacts

    Can it be plugged into an Arduino?

Topic summary

The discussion revolves around the use of a WiFi relay's NO/NC connector for controlling 12V devices in a SmartHome system. Users clarify that the relay can handle a contact current capacity of 10A at 250V AC and can switch devices on and off. It is confirmed that 12V can be applied to the contacts for controlling devices like light bulbs, but there is some ambiguity regarding whether the connector is voltage-free or can carry voltage. One response indicates that the presence of three terminals suggests it is a voltage-free contact. The author also inquires about the compatibility of the relay with Arduino.
