🌐 Shelly PRO 3: Advanced DIN Rail Smart Relay Module

Shelly PRO 3 is a new addition to the PRO series from Shelly. These products are unique because they allow connectivity not only via WiFi and Bluetooth but also via LAN. This wired connection ensures absolutely seamless communication with your network.

At first glance, it is clear that Shelly PRO modules are designed for installation on a DIN rail, directly into the distribution box. They provide a great opportunity for a neat installation where all elements are always perfectly organized and within reach.

Shelly PRO 3 offers three potential-free relays that can collectively switch up to 48A (16A per channel). Their huge advantage is the ability to switch three different phases.

Because all relays are potential-free (dry contacts), Shelly PRO 3 can be used to switch almost anything—from lighting circuits and sockets to garage doors, 3-phase boilers, or 3-phase pumps. Naturally, you can connect a physical switch for each circuit if the electrical wiring allows it.

Integration with voice assistants (Google, Alexa) and HomeKit is fully supported. However, the greatest strength for developers remains the open REST API support.
