Shelly Pro 4PM

Shelly Pro 4PM -- 4-Channel DIN Rail Smart Switch with Power Metering and Colour Display (WiFi + LAN + Bluetooth) Four independent circuits. One DIN rail device. The Shelly Pro 4PM is a professional 4-channel smart relay with per-channel power metering, a 1.8-inch colour display, and triple connectivity. Each channel supports up to 16A with a total device capacity of 40A. Monitor and control four separate circuits from a single DIN rail module -- lights, fans, pumps, heaters -- each with independent energy tracking. The built-in colour screen shows real-time status and power readings at the panel without needing a phone. Supports KNXnet/IP for commercial building management. WiFi + Ethernet + Bluetooth. No hub or subscription required. Made in Bulgaria. ⚡ 4 x 16A 40A Total 📊 Per-Channel Metering 4 Independent Meters 📺 Colour Display 1.8 Inch Screen 🌐 WiFi + LAN + BT + KNXnet/IP Key Features 4 Independent Channels, 16A Each -- switch four separate circuits with a total device capacity of 40A (4 x 3,680W at 230V); each channel operates independently Per-Channel Power Metering -- real-time voltage, current, active power, and accumulated kWh for each of the four channels separately 1.8-Inch Colour Display -- built-in screen shows channel status, power readings, and network info directly at the DB board; no phone required for quick checks 4 Switch/Button Inputs -- connect up to 4 existing wall switches or push buttons (S1-S4) for physical control of each channel Triple Connectivity -- WiFi 802.11 b/g/n, Ethernet RJ45, and Bluetooth 4.2; Ethernet provides reliable wired connectivity inside metal panels KNXnet/IP Support -- integrates with KNX building management systems for commercial installations Overpower and Overvoltage Protection -- configurable thresholds per channel protect loads and the device Smart Scheduling -- up to 20 schedules per device including sunrise/sunset-based automation Scripting (mJS) -- custom on-device JavaScript automations for complex logic, load sequencing, or conditional switching Home Assistant Native -- auto-discovered; each channel appears as a separate switch with energy entities for the HA Energy Dashboard MQTT, HTTP, WebSocket -- full API access for custom integrations, dashboards, and building management Voice Control -- Amazon Alexa, Google Home, Samsung SmartThings No Hub or Subscription Required -- fully standalone operation Perfect For 💡 Multi-Zone Lighting Control 4 lighting zones from one DIN module. Monitor energy per zone. Schedule each independently. One device replaces four separate relays. 🏢 Commercial Buildings KNXnet/IP integration for professional BMS. Per-channel metering for tenant billing. Ethernet for reliable panel connectivity. Colour display for maintenance staff. 🏠 Whole-House Automation Geyser on channel 1, pool pump on 2, garage on 3, outdoor lights on 4. Each with independent scheduling and energy tracking. View everything on one colour display. ☀ Solar Load Management Use scripting to prioritise loads based on available solar. Shed non-critical circuits first. Monitor each load's consumption independently.

Yes. All 4 channels operate independently. Each has its own relay, switch input, schedule, and power meter. You can turn channel 1 on while channels 2-4 are off, or any combination. What does the colour display show?The 1.8-inch colour screen shows the status of all 4 channels (on/off), real-time power consumption per channel, network connectivity status, and device information. Navigate using the built-in keys. Can it handle 40A total? Yes -- but 40A is the total device maximum across all 4 channels combined. Each individual channel is rated for 16A. Running all 4 channels at 16A simultaneously exceeds the total capacity -- size your loads accordingly. Does it work with Home Assistant? Yes. Auto-discovered via the Shelly integration. Each channel appears as a separate switch entity with its own energy sensor. All 4 channels feed into the HA Energy Dashboard independently. How wide is it on the DIN rail?The Pro 4PM occupies approximately 4 DIN modules (53 mm wide). Check your DB board for available rail space before purchasing. Need Help?
