Load shedding
Keep track of how much energy your solar panels and wind turbines are generating and save effortlessly by controlling your consumption with Shelly Pro 3EM Add-on.  Connect Shelly Pro Add-On to your appliances and use Shelly  Pro 3EM's real-time information on how much energy has been generated and consumed. When you need to save energy, Shelly Pro3EM Add-on can automatically switch off non-essential appliances in your home.

Weather-based control
Shelly Pro 3EM, enhanced with the Shelly Pro 3EM Add-on, offers weather-driven energy optimization. By scripting, you can efficiently control your appliances based on the weather forecast. Upon receiving real-time weather updates, Shelly Pro 3EM takes measures as defined in the script. For example, if the forecast indicates that it's going to be a sunny day, Shelly Pro 3EM Add-On can automatically turn off the heating anticipating higher temperatures.

PV systems balancing
When your PV system is producing more energy than your home consumes, Shelly Pro 3EM Add-On can automatically activate appliances to make use of it. For example, you can set it to turn on your water heater, charging station for electric vehicles, or other energy-intensive appliances. This way, you make the most of the abundant energy generated by your PV system and reduce dependency on the grid.

Full compatibility
Shelly devices are compatible with Alexa, Google Home, Android and iOS. Together with the voice assistant, you can command Shelly devices using just your voice!
