Examples of use

Reduction in consumption
Track how much energy your solar panels and wind turbines are generating and save easily by monitoring your consumption with Shelly Pro 3EM. Connect the Shelly Pro Add-On to your devices and use Shelly Pro 3EM's real-time information on how much energy has been generated and consumed. When you need to save energy, the Shelly Pro 3EM Add-on can automatically switch off non-essential devices in your home.

Weather-based control
Shelly Pro 3EM, enhanced with the Shelly Pro 3EM Add-on, offers weather-based energy optimisation. With the help of scripts, you can manage your devices efficiently based on weather forecasts. After receiving real-time weather updates, Shelly Pro 3EM performs the actions defined in the script. For example, if the forecast indicates that it will be a sunny day, the Shelly Pro 3EM Add-On can automatically turn off the heating in anticipation of warmer temperatures.

Balancing PV systems
When your PV system produces more energy than your home uses, the Shelly Pro 3EM Add-On can automatically activate devices to make use of it. For example, you can set it to switch on your water heater, electric vehicle charging station or other energy-intensive devices. This will help you make the most of the abundant energy produced by your PV system and reduce your dependence on the grid.
