Use Cases
Never forget about your appliances again!
Easily monitor and control all your plugged-in appliances with just a few clicks on your phone. The Shelly Plug US Gen4 is equipped with an integrated countdown timer and locally stored schedules, allowing it to automatically switch off any forgotten device after an hour to help you save energy.
For instance, you can manage appliances like irons, smaller ovens, and electric radiators effortlessly.
Avoid unnecessary energy waste by automating your electrical appliances
Take a step towards efficiency by automating the appliances in your office that remain idle at night or during the weekend. Simply incorporate the Shelly Plug US Gen4 to enable smart schedules that automatically power off unused electrical devices between 7:00 PM and 7:00 AM on weekdays, as well as between 7:00 PM on Friday and 7:00 AM on Monday. This thoughtful approach will halve the energy consumption of these appliances, leading to a significant reduction in your monthly energy costs.
For instance, you can use these schedules to automate smaller ovens, heating electrical radiators, and IR heaters.
Air purifier that follows the air conditions
Living in a bustling city exposes you to high levels of air pollution, particularly in the fall and winter months. With Shelly Plug US Gen4 scripting capabilities, you have the power to retrieve data directly from air pollution control systems. This allows you to program your existing air purifier to activate automatically when outdoor pollution levels rise.
For instance, through scripting, you can seamlessly automate your air purifier device, regulating its operation based on real-time data from third-party sources.
Enhance your nighttime experience
Experience a soothing color night light feature with customizable settings.
By activating the Night mode, you can enjoy a dimmed LED indication on your Shelly Plug US Gen4 during the night hours. This gentle glow ensures you have a peaceful and uninterrupted night's sleep.
Mildly dimmed night light for children's comfort
