Countdown timer

No more forgetting to turn appliances off.  The integrated countdown timer will automatically turn off your electrical devices for you.

Lighting control

Are you about to go to bed and need to switch off all the lights? So annoying! To avoid this, install Shelly 1 PM switches in your home, and control your lights or electrical appliances with just one tap via your smartphone, or your voice. With the compact Shelly 1 PM, you can make any light switch smart.

Full Compatibility

Shelly devices are compatible with Alexa, Google Home, Android and IOS.  With the voice assistants, you can command Shelly 1 with your voice for those times when you don't have your smartphone around.


If installing in Australia, this device must be installed by a certified electrician.

Warranty and Returns

Typically, when purchasing Shelly devices directly from Europe or from other retailers, warranty claims are lengthy and expensive as the device must be shipped back to Europe. 

When purchasing from the Smart Guys, if you have a fault with your Shelly Relay within 12 months of installation, give us a call and we will ship you out a new relay within 5 business days of assessment.
