Dry contacts DIN rail mountable *Only compatible with Shelly Pro 3EM!
Load Shedding:
Keep track of how much energy your solar panels and wind turbines are generating and save effortlessly by controlling your consumption with the Shelly Pro 3EM add-on. Connect Shelly Pro 3EM Add-on to your devices and use Shelly Pro 3EM's real-time information about the amount of energy produced and consumed. If you need to save energy, the Shelly Pro 3EM add-on can automatically turn off unnecessary devices in your home.
Weather-dependent control:
Shelly Pro 3EM, enhanced with the Shelly Pro 3EM add-on, offers weather-controlled energy optimization. With the help of scripts, you can efficiently control your devices based on the weather forecast. After receiving real-time weather data, Shelly Pro 3EM takes the actions defined in the script. For example, if the forecast shows that it will be a sunny day, Shelly Pro 3EM Add-On can automatically turn off the heating to avoid higher temperatures.
Balancing PV systems:
If your PV system produces more energy than your home uses, Shelly Pro 3EM Add-On can automatically activate devices to use that energy. For example, you can set your water heater, electric vehicle charging station, or other energy-intensive devices to turn on. In this way, you make abundant use of the energy generated by your PV system and reduce your dependence on the power grid.
