Powerful Wi-Fi Smart Relays That Fit Behind Any Switch

Shelly makes compact Wi-Fi and Bluetooth smart relays that install behind existing light switches, power outlets, and circuit breakers. They add smart control to any electrical circuit without changing the visible hardware — your existing switches stay in place.

WHY WE BUILD ON SHELLY

Our experience with Shelly

Shelly devices are essential to our retrofit projects. When clients want to make existing lighting, fans, or appliances smart without replacing switches or fixtures, Shelly relays fit behind the existing switch plate and add wireless control. We deploy Shelly across apartments and villas for lighting automation, energy monitoring, and appliance control — all integrated into Home Assistant for unified management.

Invisible Installation.

Fits behind existing switches and outlets. Your home looks exactly the same, but everything becomes smart and controllable remotely.

Local API & No Cloud Required.

Shelly devices work locally without any cloud dependency. Direct integration with Home Assistant for fast, private automation.

Energy Monitoring.

Many Shelly devices include built-in power monitoring. Track energy consumption per circuit and identify waste.

Dimming & Roller Shutter Control.

Specialized models for dimming lights and controlling motorized blinds/shutters. One device type for each electrical need.

A RECENT SHELLY BUILD

3-bed townhouse, Mira, Reem · 2,400 sqft

24 Shelly 1PM Mini relays installed behind existing wall switches throughout the townhouse, 6 Shelly Dimmer 2 in living/dining/master, 2 Shelly EM in the main panel for energy monitoring. Home Assistant for scenes and voice control.

AED 9,800. Done in 2 days. Owner says the wall switches still work exactly as before for the kids and guests, but everything has scenes, schedules and voice control underneath. Energy visibility caught two appliances drawing more than they should.

Imran V.

I didn't want to replace any of my switches. The team installed Shelly relays behind every switch I cared about and now the whole townhouse responds to scenes, schedules and voice. From the wall it looks identical to the day we moved in.

Frequently asked questions

What exactly is a Shelly relay?+
A Shelly relay is a small Wi-Fi device that installs behind your existing light switch or outlet. It makes the circuit smart — controllable by app, voice, or automation — without changing the switch on the wall.
Can I still use my regular light switch with Shelly?+
Yes. That's the beauty of Shelly — your existing switch continues to work normally for manual control, while also gaining app, voice, and automation control.
Does Shelly need a hub?+
No. Shelly devices connect directly to your Wi-Fi network. For advanced automations, we integrate them with Home Assistant, but they work standalone too.
How much do Shelly devices cost in Dubai?+
A Shelly relay starts from around AED 50-80. Making an entire apartment's lighting smart with Shelly typically costs AED 1,500-4,000 including installation.
Is Shelly safe for electrical installation?+
Yes. Shelly devices are CE certified and designed for permanent electrical installation. We handle all wiring professionally and ensure compliance with local regulations.
