Short Description
Shelly Outdoor Plug S Gen3 is one of the first Shelly devices designed for outdoor use and comes with Matter support.
The Shelly Outdoor Plug S Gen3 is a smart plug/outlet with power measurement and overheating protection, enabling remote control of electric appliances via mobile phone, tablet, PC, or home automation systems. It can operate standalone on a local Wi-Fi network or be managed through cloud-based home automation services.
You can access, set up, and monitor the device remotely from anywhere with internet connectivity, provided the device is connected to a Wi-Fi router and the Internet.
The device includes an embedded web interface for monitoring, controlling, and adjusting settings.

Use Cases
- Garden Automation: Automate garden light strips, electric grills, stoves, or other outdoor appliances to manage operation and energy consumption efficiently.
- Seamless integration with other Matter devices
- Use with Apple devices (via Matter)
- Use as a color night light:
- Night mode with custom settings
- When turned on, night mode reduces the LED brightness during nighttime hours to ensure undisturbed sleep.
- Prevent forgotten appliances from being left on:
- Monitor and control plugged-in devices easily via smartphone.
- Thanks to countdown timers and locally stored schedules, the plug can automatically switch off forgotten devices after one hour to save energy.
- Example: Irons, small ovens, electric radiators
- Automate office appliances to avoid energy waste:
- Set smart schedules to turn off unused devices between 7:00 PM and 7:00 AM on weekdays, and Friday evening to Monday morning.
- This cuts energy usage in half, significantly reducing monthly energy costs.
- Example: Small ovens, electric radiators, IR heaters
- Air purifier that responds to air quality:
- Using scripting capabilities, extract real-time air pollution data and trigger your air purifier to turn on when pollution levels rise.
- Example: Automate an air purifier based on external environmental data
- Subtle night light for children’s comfort:
- Customize the LED color and brightness to create a soft glow ideal for kids' rooms at night.
