More details

More info


Shelly Plus i4 DC allows you to manually activate or deactivate any created scene, run synchronized actions, or execute complex trigger scenarios.

Enhanced with an extremely fast processor, Shelly Plus i4 DC will immediately command the execution and notification of various actions. You can use Shelly Plus i4 DC to control other connected Shelly relays, sensors, or HTTP and MQTT-controlled devices.

Small enough to behind every wall switch, Shelly Plus i4 DC can show the status and control the action of four inputs.

Multi-actions support

Install Shelly Plus i4 DC where it is most convenient to you and use it to activate various scenes or actions from the other Shelly devices in your home with as much as a push of a button. Shelly Plus i4 DC supports up to 3 different actions per button, which makes it extremely convenient for quick manual control over a group of devices.

Ultimate comfort

One of the most frustrating things is to realize you forgot to switch off the lights in the living room before you go to bed. Especially when your phone is nowhere around. But there is no need to worry! Shelly Plus i4 DC allows manual control of other Shelly devices. Now the full control of your house is just one hand away!

Complex scenes control

Manually activate or deactivate complex scenes. With Shelly Plus i4 DC you can run synchronized actions of several Shelly devices. You can install Shelly Plus i4 DC close to the front door of your home and turn off/on all the lights in your house with one push of the button, saving you time when you are in a hurry.

Perfect match

Shelly Plus i4 DC is perfect for Shelly Wall Switch for Smart Relays – 4 button switch. Each button can activate up to 3 different actions. That means that only one 4 button switch would allow as much as 12 scenes trigger and execution!

Thanks to its compact dimensions and simple wiring, Shelly Wall Switch for Smart Relays can fit into any existing switch console or even the tiniest spaces. No expansion of the wall space or any changes in the wiring needed!

Highly compatible

Use Amazon Alexa to control Shelly Plus i4 DC and activate scenes using your voice!
