Shelly 1 Wiring Diagram

Before we get into the details of wiring the Shelly 1, let’s take a look at the wiring diagram below. This diagram shows how to wire the Shelly 1 to a standard light switch.

Shelly 1 Wiring Light Switch
L Live wire (black) Connected to common terminal (COM)
N Neutral wire (white) Connected to neutral terminal (N)
IN Input wire (black) Connected to live wire (black) from the electrical supply
SW Switch wire (red) Connected to the switch terminal (L1)
OUT Output wire (black) Connected to the live wire (black) going to the light fixture

The Shelly 1 has five terminals, namely L, N, IN, SW, and OUT. You can easily identify these terminals by looking at the label on the device or the manual that comes with it.

Now let’s take a closer look at how to wire each of these terminals:

L Terminal

The L terminal on the Shelly 1 is for the live wire or the wire that carries the electrical current. This wire is typically colored black or brown. To wire the L terminal, you need to connect it to the common terminal (COM) on your light switch. This is usually the terminal where the black wire from the electrical supply is connected.

N Terminal

The N terminal on the Shelly 1 is for the neutral wire or the wire that carries the return current. This wire is typically colored white or gray. To wire the N terminal, you need to connect it to the neutral terminal (N) on your light switch. This is usually the terminal where the white wire from the electrical supply is connected.

IN Terminal

The IN terminal on the Shelly 1 is for the wire that carries the live current from the electrical supply. This wire is typically colored black or brown. To wire the IN terminal, you need to connect it to the black wire from the electrical supply.

SW Terminal

The SW terminal on the Shelly 1 is for the wire that is connected to the switch. This wire is typically colored red or blue. To wire the SW terminal, you need to connect it to the switch terminal (L1) on your light switch. This is usually the terminal where the red wire from the switch is connected.

OUT Terminal

The OUT terminal on the Shelly 1 is for the wire that carries the live current to the light fixture. This wire is typically colored black or brown. To wire the OUT terminal, you need to connect it to the black wire going to the light fixture.

FAQs

Do I need a neutral wire to install the Shelly 1?

Yes, you need a neutral wire to install the Shelly 1. The neutral wire is required to power the device and to complete the circuit. If you don’t have a neutral wire, you will need to hire an electrician to install one for you.

Can I use the Shelly 1 with a two-way switch?

Yes, you can use the Shelly 1 with a two-way switch, but you will need to wire it differently. You will need to use two Shelly 1 devices, one for each switch, and wire them in parallel. This will allow you to control the same light or device from multiple switches.

Can I install the Shelly 1 behind a metal switch plate?

What is the maximum load that the Shelly 1 can handle?

The Shelly 1 can handle a maximum load of 16 amps or 3,500 watts. This is more than enough to handle most light fixtures and electrical devices.

Can I control the Shelly 1 with my smartphone?

Yes, you can control the Shelly 1 with your smartphone using the Shelly Cloud app. The app is available for free on the App Store and Google Play Store.
