Shelly Pro 4PM

The best solution for new home buildings and business facilities
Shelly Pro 4PM is a one-phase, 4-channel relay, supporting up to 16A per channel with a total device capacity of 40A. Shelly Pro 4PM is equipped with four integrated precise power meters that allow you to control and monitor the consumption for each channel separately. Equipped with LAN, Wi-Fi, and Bluetooth connectivity, it allows for a more secure and reliable connection. Use scripting functionalities to set custom automation scenes based on various occurrences, weather forecasts, wind forecasts, etc.

Shelly Pro series
Enhanced with temperature, overpower, and overvoltage load protection, Shelly Pro series is designed to be installed inside the breaker box (DIN). Allowing full smart automation with no additional cables or wiring, Shelly Pro line is perfect for homes, offices, stores, business, and manufacturing facilities, as well as new buildings.

LAN, Wi-Fi, and Bluetooth connectivity
LAN connection for high security and reliability. Simultaneous Wi-Fi and LAN usage, as backup when needed.

Appliances control and monitoring
Predict monthly costs and plan your spending better! Automate the electrical appliances in the restaurant and track their energy consumption wherever you are. Shelly Pro 4PM will inform you in case an appliance is forgotten and left working outside of restaurant working hours, notifying you to switch it off to avoid electricity consumption waste. Additionally, you can set smart schedules and have Shelly cut off the power to all unused electrical appliances during the night and turn them back on right before the kitchen opens.

Temperature control for better productivity
Research shows that employees' productivity decreases when there are temperature fluctuations in the office. The cooling and heating systems in the building should follow the dynamic changes in the temperatures during the different seasons. Connect Shelly Pro 4PM to the motorized electrical valves in your water distribution box and control your heating and cooling efficiently. Smart schedules combined with temperature & humidity sensors and precise weather data will provide dynamic control of the heating system for an optimal office indoor climate.

Automation of the common spaces for efficient energy usage
Reduce unnecessary monthly costs with Shelly smart lighting solutions. Shelly Pro 4PM can measure and control four separate light circuits and give you full control over common spaces such as halls, garages, and storage rooms, which usually have their lights constantly switched on. Now you can make them energy efficient using Shelly Pro 4PM's built-in scheduling and scripting functionalities. To fully automate your premises, add Shelly Motion2 to switch on the lights automatically when someone enters, and its pre-set smart timer will switch the lights off once the premises are empty.

Load shedding
Keep track of how much energy your solar panels and wind turbines are generating and save effortlessly by controlling your consumption with Shelly Pro 4PM. Connect Shelly Pro 4PM to your appliances and use Shelly 3EM's real-time information on how much energy has been generated and consumed. When you need to save energy, Shelly Pro 4PM can automatically switch-off non-essential connected appliances in your home.

Safety
Temperature protection / Overpower protection (PM devices) / Overvoltage load protection (PM devices) / Flame Retardant (V-0)

Features
HTTP/HTTPS webhooks / Sunrise/Sunset actions with offsets / Weekly Scheduling / Custom scripts(mJs) / Grouping Scenes

Overheating protection
In case of unsafe temperature levels or rapid temperature increase, device switches off the outputs and sends notification. Internal temperature sensor is measuring the heat every 100 ms.

Overpower protection
Detected overpower will lead to outputs switch off by the device and it will immediately send a notification. Overpower protection feature protects the device and other electrical equipment from potential damage. (Feature is available only for power metering-enabled devices)

Overvoltage protection
Voltage peaks could be dangerous for electrical appliances and machines. To avoid damage to the electrical appliances the device switches off the outputs when overvoltage peaks are detected and immediately sends a notification. (Feature is available only for power metering-enabled devices)

Flame Retardant (V-0)
All Shelly Pro components are produced with flame-resistant materials and will keep their construction even when exposed to high levels of heat.

HTTP/HTTPS webhooks for quick connection
Enhanced with HTTP/HTTPs webhooks, Shelly Pro line can easily connect with, notify or control other compatible equipment or 3rd party automation system.

Smart actions that follow the Sunrise/Sunset
Shelly Pro line can switch on/off the power, depending on the Sunset/Sunrise hour, allowing dynamic control of the electrical equipment depending on the season.

Automation with weekly scheduling
Shelly Pro line allows you to set up to 20 actions based on your daily or weekly schedule with no need for an external hub or server.

Scripting for custom automation
Shelly Pro line fully supports mjS scripting, allowing customers to create their own features and functionalities.

Full compatibility
