How to add a Shelly device to the Shelly app
Add a Shelly relay or dimmer to the Shelly Smart Control app over Bluetooth, step by step, with fixes for when the app can't find it.
Which Shelly do I need?
Tell us the job, and where it matters, the wiring and how you want to control it, and we'll tell you which model to buy.
Shelly 1 vs 1PM vs 2PM: which one do you need?
The Shelly 1, 1PM and 2PM fit behind the same light switch and cost $34.95 to $49.95. Here's what separates them, and which one suits your job.
Shelly generations: Gen 3 vs Gen 4 vs Pro
Shelly's range runs Gen1, then Plus and Pro, then Gen3 and Gen4. Here is what actually changes between them, and why a Pro is not a step above a Gen4.
Should you run Shelly on Zigbee or Wi-Fi?
Zigbee is alternative firmware on Gen 4 Shellys, not a second radio. What you gain, what leaving Wi-Fi costs you, and how to switch without losing your configuration.
Does Shelly work without the internet?
Yes, and the wall switch works even with the router unplugged. What keeps running without internet, what stops, and the clock problem that breaks schedules after a power cut.
Will it do the job?
What each relay is rated to switch, what lands on which terminal once the wall is open, which meter fits your switchboard, and how Shelly reaches Matter.

What can a Shelly switch? Load ratings explained
Every Shelly relay and dimmer we stock, what each one is rated to switch, and why the type of load matters more than the wattage.

Which Shelly energy monitor do you need?

Shelly and Matter: supported devices, setup and limits
Gen4 Shellys ship with Matter on by default; Gen3 needs a firmware update and a toggle. Which devices support it, what your network needs, and how to pair with Apple Home, Google Home or Alexa.

Add a Shelly BLU door, window or motion sensor to the Shelly Smart Control app, choose the Shelly that acts as its Bluetooth gateway, and fix one that stops reporting.
Shelly switch modes: which input mode suits the switch on your wall
The relay is wired correctly and the light still misbehaves. Usually the input mode does not match the switch on the wall. Here is which mode suits which switch.
How to install a script on a Shelly
Install a script on a Shelly from the Shelly app or a browser, step by step: create it, paste the code, run it, and keep it running after a restart.

Enter your electricity rate in the Shelly app, flat or time-of-use, so your energy readings line up with the prices on your bill.
The Shelly app: what's free, and what Premium adds

What people do with Shelly
A roof-space fan that runs when the roof gets hot

Bathroom fan that clears the steam, then turns itself off

A sensor on the door or window and a rule that waits. If it is still open after five minutes, your phone gets told, and a nearby light can come on as well. Control with any of

Lights that come on as you walk in, softer late at night

Outdoor lights on at sunset, off at midnight

Run the hot water on off-peak or solar
Put the hot water system on a timer, so it heats on overnight off-peak rates or in the middle of the day on your solar. One schedule on one circuit, and you can see what every heat-up uses. Control with any of
