Use cases
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.
