Add-on for Shelly Pro 3EM

A galvanically isolated switch designed to expand the capabilities of your Shelly Pro 3EM. This additional device allows you to easily control contactors and other electrical devices, giving you more flexibility and control over your consumption.

Load Shedding - Keep track of how much energy your solar panels and wind turbines are producing and save effortlessly by controlling your consumption with the Shelly Pro 3EM add-on. Connect the Shelly Pro 3EM add-on to your devices and use Shelly Pro 3EM's real-time information about the amount of energy generated 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, expanded with the Shelly Pro 3EM add-on, enables weather-controlled energy optimization. Using scripts, you can efficiently control your devices based on the weather forecast. After receiving real-time weather data, Shelly Pro 3EM implements the actions defined in the script. For example, the Shelly Pro 3EM add-on can automatically turn off the heating when the forecast shows a sunny day to avoid higher temperatures.

PV system balancing - If your PV system produces more energy than your home uses, the Shelly Pro 3EM add-on can automatically activate devices to use this excess energy. For example, you can Set your water heater, electric vehicle charging station, or other energy-intensive devices to turn on. This allows you to use the energy generated by your PV system efficiently and reduce your dependence on the power grid.

The addon is only compatible with Shelly Pro 3EM!
