FAQ

Q: Can I switch 24vdc with this unit and also power the unit itself from 24vdc?
A: No, you need to use Shelly 1 because it has dry contact and can handle DC up to 24volts.

Q: Can I send on/off commands to Shelly and receive inputs via an API or my own Android application?
A: Yes, these devices work with the normal cloud apps, or can be accessed directly by a browser on Android, Windows, or iOS. They provide feedback to the browser to indicate their state as well.

Q: Can this be controlled with Alexa?
A: Yes, it is compatible with Alexa and Google Home.

Q: Can any Shelly relay be programmed so the output is momentary? I need 500ms-1000ms on and then off again.
A: Yes, you can program the Shelly 2.5 in the timer section for the quantity of seconds to remain ON or to remain OFF. It can be programmed for 0.5 seconds or a number of seconds.

Q: Will this work with SmartLife-SmartHome?
A: No, it is not currently supported.

Q: Can I use this for a DC motor and be able to reverse rotation?
A: Yes, but you will need some relays or extra components to accomplish this. If you are not comfortable with electronics, you should seek qualified help with this.

Q: Can I use this as an I/O sensor?
A: The question is unclear. If you want to determine the status of the switch (on/off), you might turn a device on or off via Shelly. You could use IFTTT to sense the status of the device and trigger something else. The device in question must be unique to the Shelly to avoid false indication.

Note: Shelly 2.5 is a compact, UL-certified WiFi smart home automation device with dual power metering that can control any appliance at home and monitor its electrical consumption via your smartphone or tablet, no matter where you are. It can control two channels independently or roller shutters up to 2x10A and can be easily fitted behind a built-in light switch, socket, junction or electrical boxes. It has built-in temperature sensors for overheating protection and can execute different actions such as turning off the current once your pre-defined limit has been reached. It can be used in roller shutter mode and has an embedded web server, making it easy to set up without the need for any additional controller or hub.
