Description

The Shelly Pro 3EM Switch Add-On is designed for DIN rail installation in the breaker box and enhances the functionality of the Shelly Pro 3EM by offering advanced features such as weather-driven energy optimization. For example, it can automatically disable heating on sunny days in anticipation of higher temperatures.

Additionally, the Pro 3EM Switch Add-On helps balance your photovoltaic (PV) system’s load by redirecting excess generated energy to power other appliances like water heaters, electric vehicle charging stations, and other energy-intensive devices, reducing reliance on the grid.

The device includes dry contacts and is DIN-rail mountable.

Note: The Pro 3EM Switch Add-On is only compatible with the Shelly Pro 3EM.
