The BEST RETROFIT device EVER made

No electrical wiring changes needed
Shelly1L can convert any existing wall switch into a smart switch. You don’t need to change the wiring, to run new cables, or anything else. Just put the shelly behind the existing wall switch.

No neutral line required
Мany light switches are wired with no neutral present, which makes them difficult to automate. Shelly1L handles this problem because it only needs the hot line.

Shelly1L can make any appliance smart

Shelly1L works with any ceiling fan, still no neutral is required.
There is no limit to the type of lights you can use with Shelly1L – LED, Tungsten, Halogen, or Luminescent bulb, can be controlled.

Smart Scheduling

Scheduling Like all Shelly products, the Shelly1L has advanced scheduling features
You can switch it on and off at a certain time, or control your light according to the sunset and sunrise hours. And that’s not all - you can offset your schedule by up to 3 hours before or after sunset/sunrise.

You can set the Auto OFF and Auto ON functions to automatically turn your Shelly1L on or off X minutes after the state changes, which makes Shelly1L the perfect solution when wired to any motion sensor or when you forgot to switch off the lights and walk away.

Control all the lights in your home together

You can create a group of lights and control all of them together with just one click. Plus, each device can be part of more than one group, giving you many control options.

Full Control Without
a Hub or Cloud

Shelly1L has a simple API which allows it to be controlled from any other Shelly or Wi-Fi based device.
You simply need to know the IP address of Shelly1L to send commands to it to change the state from anywhere.

Powerful direct actions

Shelly1L can control any other Wi-Fi device in your home.
You can set a local action into each device that will execute when the switch is toggled or the output state is changed.
As many as 5 actions per Shelly device allow you to control up to 5 other devices at once.


One application countless possibilities

With the best cloud service in the world, user-friendly interface, scenes, bulk control, and much more, the Shelly Cloud application allows you to control your home from anywhere. Each Shelly can be integrated and works with all other Shelly devices in the Shelly app.
