Use cases
- Use seamlessly and integrate together with other Matter devices
- Use with Apple devices (via Matter)
- Use it as a color night light:
- Night mode with custom settings
- When switched on, the Night mode reduces the brightness of the LED indication during night hours for undisturbed sleep.
- No more forgotten appliances on:
- Monitor and control all plugged-in appliances easily with just a few taps on your phone.
- Thanks to its integrated countdown timer and locally stored schedules, the Shelly Plug S MTR Gen3 can automatically switch off any forgotten device after an hour to save energy.
- Example: Iron, small ovens, heating electrical radiators
- Avoid energy waste by automating your electrical appliances:
- Automate office appliances not used at night or weekends using Shelly Plug S MTR Gen3.
- Set smart schedules to turn off power between 7:00 PM and 7:00 AM on weekdays, and from 7:00 PM Friday to 7:00 AM Monday — cutting energy consumption in half and optimizing monthly costs.
- Example: Smaller ovens, heating electrical radiators, IR heaters
- Air purifier that follows air conditions:
- If you live in a polluted urban area, especially during fall and winter, use scripting to extract real-time air pollution data and automatically turn your air purifier on when pollution levels rise.
- Example: Automate an air purifier based on third-party environmental data.
- Mildly dimmed night light for children's comfort:
- Customize the color and brightness of the LED indicator to create a soft ambient light ideal for kids’ rooms at night.
