SHELLY-SWI-PRO-1PM

Shelly Pro 1PM -- 1-Channel DIN Rail Smart Switch with Power Metering (WiFi + LAN + Bluetooth) Professional-grade smart switching for your DB board. The Shelly Pro 1PM is a single-channel DIN rail smart relay with built-in power metering, designed for breaker-box installation. It supports 16A loads with real-time energy monitoring delivered to the Shelly app. Triple connectivity -- WiFi, Ethernet (LAN), and Bluetooth -- ensures reliable control in any environment, including areas with poor wireless coverage. No hub required. Works with Home Assistant, Alexa, Google Home, Samsung SmartThings, plus MQTT, HTTP, and WebSocket for advanced integrations. Scripting support (mJS) enables custom automations directly on the device. Made in Bulgaria. ⚡ 16A Output Single Channel 📊 Power Metering Real-Time V/A/W/kWh 🌐 WiFi + LAN + BT Triple Connectivity 🏠 No Hub Needed HA, Alexa, Google Key Features 1-Channel Relay, 16A -- switch one circuit up to 16A (3,680W at 230V) for lights, fans, heaters, pumps, or any single-circuit load Built-in Power Metering -- real-time voltage, current, active power, and accumulated energy (kWh) reported to the Shelly app and Home Assistant Triple Connectivity -- WiFi 802.11 b/g/n, Ethernet RJ45 (LAN), and Bluetooth 4.2; Ethernet ensures rock-solid connectivity in noisy DB board environments DIN Rail Mounting -- standard DIN rail form factor (94 x 19 x 69 mm); fits inside any residential or commercial distribution board No Hub Required -- connects directly to your WiFi or LAN network; no gateway, bridge, or subscription needed Home Assistant Native -- auto-discovered via Shelly integration; full local control over LAN with no cloud dependency Voice Control -- Amazon Alexa, Google Home, and Samsung SmartThings compatible Smart Scheduling -- up to 20 schedules including sunrise/sunset-based automation Scripting (mJS) -- run custom JavaScript-based automation scripts directly on the device; no external server needed MQTT, HTTP, WebSocket -- full API access for advanced integrations and custom dashboards Overpower and Overvoltage Protection -- built-in safety features protect connected loads and the device itself 2 Switch/Button Inputs -- connect existing physical wall switches or push buttons (SW1 and SW2) Internal Temperature Sensor -- monitors device temperature for thermal protection Dry Contacts -- relay output uses dry contacts for flexible wiring configurations OTA Firmware Updates -- over-the-air updates via WiFi or LAN keep the device current TLS Security -- supports MQTT with TLS, WSS, and custom certificates for secure communication Perfect For 💡 Lighting Circuits Automate a lighting circuit from the DB board. Schedule lights, control via app or voice, and monitor energy consumption per circuit. 🌡 Geyser and Heating Switch a geyser or underfloor heating contactor on schedule. Monitor kWh consumption to track running costs. Overpower protection built in. 🏭 Commercial and Industrial LAN connectivity ensures reliability in commercial panels. MQTT and scripting enable integration with building management systems. 20 schedules per device. 🛠 Pool Pumps and Motors Schedule pump run times and monitor energy usage. Set overpower thresholds to detect blockages or faults. Control from anywhere via the app. Why Ethernet matters: DB boards are metal enclosures that weaken WiFi signals. The Shelly Pro 1PM includes an RJ45 Ethernet port so you can run a cable directly to your router or switch. This eliminates WiFi dropouts and gives you reliable, low-latency local control -- especially important for Home Assistant automations.

No. The Shelly Pro 1PM connects directly to your WiFi network or via Ethernet cable. No hub, bridge, or gateway required. No subscription either. Does it work with Home Assistant? Yes. Home Assistant auto-discovers Shelly devices via the built-in Shelly integration. All control is local over LAN -- no cloud dependency. Full power metering entities are exposed. Can I use it with my existing wall switch? Yes. The Pro 1PM has two switch/button inputs (SW1 and SW2). Connect your existing toggle switch or push button for physical control alongside app and voice control. Will it fit in my DB board? Yes. Standard DIN rail mounting at 94 x 19 x 69 mm -- approximately 1 DIN module wide. Fits in any residential or commercial distribution board. Why choose Ethernet over WiFi?DB boards are metal enclosures that attenuate WiFi signals. Ethernet provides a reliable, low-latency wired connection that avoids wireless interference. The Pro 1PM supports both -- use whichever suits your installation. Can I run custom automations on the device? Yes. The Pro 1PM supports mJS scripting -- write custom JavaScript-based logic that runs directly on the device. Useful for timer sequences, conditional switching, or integration with external APIs.
