4-channel-din rail relay switch with performance measurement, Wi-Fi, LAN and Bluetooth connection

Already flashed with the latest Tasmota firmware.

First-class house or building automation with the new, professional line of the Shelly Wi-Fi and Bluetooth relay with LAN connection and exact energy management and control. Extended with temperature, over-current and overvoltage protection, the Shelly Pro series is designed for installation in the fuse box. The product series enables complete intelligent automation from the safety box without additional cables or wiring. The Shelly Pro series is perfect for residential buildings, offices, shops, companies and production facilities.

The best solution for new buildings

The Shelly Pro-Line enables complete intelligent automation in the control cabinet. This makes them the perfect solution for new buildings and production facilities, which you can plan and adapt individually according to your needs. In the meantime, the precise consumption measurement of the PM devices informs you about the electricity consumption of each connected device. So you can reliably analyze the data and reduce consumption costs.

Lan, Wi-Fi and Bluetooth simultaneous Wi-Fi and LAN use. Fast and easy adding of devices via Bluetooth connection.

Can be assembled on DIN rail. Enables intelligent automation directly from the fuse box. Manage and control your system, no matter where you are.

Protection, overload and surge protection protection of the load.

Shelly Pro Line devices can be operated directly and without a hub via your smartphone with Shelly Cloud app.

Control of lights, roller shutters, garage gates, gates, awning, blinds, swimming pool covers, bidirectional alternating motors.

improved security functions

Overheating protection-In the event of too high temperature or rapid temperature rise, the device switches off the outputs and sends a notification. The internal temperature sensor measures the heat every 100 ms.

Overload protection-If the overload is recognized, the device switches off the outputs and immediately sends a notification. The overvoltage protection function protects the device and other electrical devices from possible damage.

Overvoltage protection- tension peaks can be dangerous for electrical devices and machines. In order to avoid damage to the electrical devices, the device switches off the outputs when overvoltage peaks are recognized and immediately sends a notification.

Flammable- all Shelly per components are made from flammable materials and keep their construction even with strong heat.

other properties

HTTP/HTTPS-Webhooks for a quick connection-expanded with HTTP/https webhooks, the Shelly Pro line can easily connect, notify or control other compatible devices or automation system of a third-party provider.

Smart processes (scenes) after sunrise/sunset- Shelly Pro Line can switch the current on and off depending on the sunset or sunrise, which is perfect for the dynamic control of the electrical devices.

Individual automation with a weekly schedule-Shelly Pro Line enables you to set up to 50 actions based on your daily or weekly plan, without you an external hub or server

Scripting for custom automation-the Shelly Pro line fully supports MJS Scripting so that customers can create their own features and functions! Several scripts can be carried out together.

Note on Tasmota firmware:

The display of the Shelly Pro4PM is supported by the Tasmota32-LVGL firmware. LVGL (Light and Versatile Graphics Library) is the next generation of Tasmota displays. It is powerful, lightweight and easy to use.

It combines:

LVGLS Powerful graphics and GUI library for embedded systems

tasotas stability, variety of functions and resource conservation

berry's powerful, micropython similar language

LVGL is an open source graphics library that offers everything you need to create a embedded graphical user interface with easy-to-use graphic elements, beautiful visual effects and low memory needs.

Further information and the documentation can be found here:

The LVGL library is already completely included in the firmware. The display is preset with 3 rules (rules) for a simple text display. The following data is visible on the display. Time, internal temperature, voltage display, switching condition of the individual channels and the current consumption of the individual channels in watts. The display updates in the second clock. The display can be switched off and switched off completely. The physical buttons switch the first 3 channels.

It is up to you to design the display display according to your individual stations. Programming knowledge is required.
