The Shelly Pro 4PM is a 4-channel DIN-rail switch actuator designed for smart home automation. It combines wired LAN connectivity with wireless WiFi and Bluetooth control, enabling flexible integration into existing building infrastructure.
4 independent switching channels control up to 4 loads from a single DIN-rail unit
Dual connectivity via LAN and WiFi ensures reliable local and remote operation
Bluetooth support enables quick, cable-free setup and configuration
Compact DIN-rail form factor fits standard electrical enclosures without additional mounting hardware
What sets the Shelly Pro 4PM apart
Unlike single-channel smart switches, the Pro 4PM consolidates four switching circuits into one DIN-rail device, reducing the number of modules needed in a distribution board. Its combination of wired LAN and wireless WiFi provides both a stable backbone connection and the flexibility of wireless control.
Ideal for...
Building automation installers and smart home integrators who need to control multiple loads — such as lighting circuits, heating zones, or ventilation units — from a single DIN-rail module in commercial or residential electrical panels.
Application of Shelly Pro 4PM
Mount the device on a standard DIN rail inside a switchboard. Connect the four switching outputs to the respective loads and the LAN/WiFi antenna to the network infrastructure. Configure channels via the Shelly cloud platform or local API to schedule, trigger, or monitor each channel independently.
