Use cases

• Smart control with Matter - seamless use with Apple devices:
  Shelly Plug M Gen3 works flawlessly with Apple Home, Alexa, Google Home, SmartThings and Home Assistant thanks to Matter support. You can instantly control lamps, heaters, fans, or any connected appliance using voice assistants, automations, or your preferred app. Enjoy simple setup, fast local control, and reliable operation across multiple ecosystems.

• Prevent forgotten appliances from wasting energy:
  Monitor and control all plugged-in appliances easily with just a few clicks on your phone. With the built-in countdown timer and locally stored schedules, Shelly Plug M Gen3 can automatically switch off appliances after a user defined period even without internet.
  Example: night lamps, fans, irons, portable ovens, electric heaters.

• Avoid energy waste by automating your electrical appliances:
  Automate appliances in the office that are not used at night or over the weekend by simply adding Shelly Plug M Gen3. Now, you can set smart schedules that will turn off the power to all unused electrical appliances between 7:00 PM and 7:00 AM during the weekdays and between 7:00 PM on Friday and 7:00 AM on Monday. That way, you will cut the energy consumption of these devices in half, which will result in significant optimization of the monthly energy cost.

• Automatic laundry / appliance cycle notification:
  Shelly Plug M Gen3 detects when an appliance’s power consumption drops, allowing you to receive a notification when a washing machine, dishwasher, or dryer finishes its cycle.

• Smart heater control based on temperature:
  Connect a portable heater and automate it using temperature data from another temperature sensor. The heater turns on when the room is cold and turns off automatically when the target temperature is reached.

• Presence simulation for home security:
  Use smart schedules to turn lamps or small appliances on and off when you're away from home, giving the appearance that someone is inside and improving security.
