With support for WiFi, Zigbee, Bluetooth, and Matter, it offers unmatched flexibility and compatibility across platforms, making it simple to integrate into your preferred smart ecosystem. Its two independent channels can control appliances, lighting circuits, or motorised covers such as blinds, shutters, and curtains — all while delivering real-time power metering for each channel, so you can track energy usage and optimise efficiency.\u003c\/p\u003e\u003cp\u003eThis device is small enough to retrofit behind existing switches, yet powerful enough to manage bi-directional AC motors with precision. You can control roller shutters, automate curtain schedules, or adjust the tilt of venetian blind slats for the perfect balance of light and privacy. The Shelly 2PM Gen4 also functions as a WiFi and Zigbee range extender and includes a Bluetooth gateway, expanding your network while connecting your devices. Built-in overheating protection, advanced scripting capabilities, and wide protocol support (including Apple HomeKit via Matter) make it a future-proof choice for both residential and commercial automation projects.\u003c\/p\u003e\u003cp\u003e• Dual-channel control on the same phase with independent power metering\u003c\/p\u003e\u003cp\u003e• Multiprotocol support: WiFi, Zigbee, Bluetooth, Matter\u003c\/p\u003e\u003cp\u003e• Cover and blinds control with precise position and slat angle adjustment\u003c\/p\u003e\u003cp\u003e• Compact design for retrofitting behind switches and sockets\u003c\/p\u003e\u003cp\u003e• WiFi \u0026amp; Zigbee extender + Bluetooth gateway functionality\u003c\/p\u003e\u003cp\u003e• Smart schedules, scenes, scripting, and local\/cloud control\u003c\/p\u003e\u003cp\u003e• Secure integrations via HTTPS, MQTT, WebSockets, and KNX\u003c\/p\u003e\u003cp\u003eWhether you’re automating lighting circuits, cutting energy costs by monitoring appliances, or creating a smart shading system that adapts to time of day and weather, the Shelly 2PM Gen4 brings intelligence, versatility, and reliability into every setup.\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eSpecifications\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-style: italic;\"\u003ePower\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003ePower supply:\u003c\/p\u003e\u003cp\u003e110-240V ±10% 50\/60Hz AC\u003c\/p\u003e\u003cp\u003e24V DC ±10%\u003c\/p\u003e\u003cp\u003eMax switching voltage AC: 240V\u003c\/p\u003e\u003cp\u003eMax switching voltage DC: 30V\u003c\/p\u003e\u003cp\u003eMax switching current AC: 10A per channel, 16A total combined (18A total peak)\u003c\/p\u003e\u003cp\u003eMax switching current DC: 10A\u003c\/p\u003e\u003cp\u003ePower consumption: \u0026lt; 1.4W\u003c\/p\u003e\u003cp\u003eExternal protection:\u003c\/p\u003e\u003cp\u003eTripping characteristic B or C\u003c\/p\u003e\u003cp\u003e16A max. rated current,\u003c\/p\u003e\u003cp\u003eMin. 6 kA interrupting rating,\u003c\/p\u003e\u003cp\u003eEnergy limiting class 3\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-style: italic;\"\u003eFeatures\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003eClean contact relay: No\u003c\/p\u003e\u003cp\u003ePower measurement: Yes\u003c\/p\u003e\u003cp\u003eVoltage protection \/ Cutoff: Yes\u003c\/p\u003e\u003cp\u003eCurrent protection \/ Cutoff: Yes\u003c\/p\u003e\u003cp\u003eMax power protection \/ Cutoff: Yes\u003c\/p\u003e\u003cp\u003eInternal-temperature sensor: Yes\u003c\/p\u003e\u003cp\u003eAmbient temperature: -20°C to 40°C \/ -5°F to 105°F\u003c\/p\u003e\u003cp\u003eHumidity: 30% to 70% RH\u003c\/p\u003e\u003cp\u003eSchedules: 20\u003c\/p\u003e\u003cp\u003eWebhooks (URL actions): 20 with 5 URLs per hook\u003c\/p\u003e\u003cp\u003eMQTT: Yes\u003c\/p\u003e\u003cp\u003eUDP: Yes\u003c\/p\u003e\u003cp\u003eScripting: Yes\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-style: italic;\"\u003eConnectivity\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003eWireless\/WiFi Protocol: 802.11 b\/g\/n\/ax (2.4 GHz)\u003c\/p\u003e\u003cp\u003eFrequency: 2412-2472 MHz\u003c\/p\u003e\u003cp\u003eWi-Fi Range (depending on local construction):\u003c\/p\u003e\u003cp\u003eUp to 50m\/160ft outdoors\u003c\/p\u003e\u003cp\u003eUp to 30m\/100ft indoors\u003c\/p\u003e\u003cp\u003eZigbee Protocol: 802.15.4\u003c\/p\u003e\u003cp\u003eZigbee Repeater: Yes\u003c\/p\u003e\u003cp\u003eZigbee RF Bands: 2400-2483.5 MHz\u003c\/p\u003e\u003cp\u003eZigbee Range (depending on local construction):\u003c\/p\u003e\u003cp\u003eUp to 300m outdoors\u003c\/p\u003e\u003cp\u003eUp to 100m indoors\u003c\/p\u003e\u003cp\u003eBluetooth Protocol: 5\u003c\/p\u003e\u003cp\u003eBluetooth Range (depending on local construction):\u003c\/p\u003e\u003cp\u003eUp to 30m\/100ft outdoors\u003c\/p\u003e\u003cp\u003eUp to 10m\/33ft indoors\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-style: italic;\"\u003eDimensions\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e(H x W x L): 37 x 42 x 16 ±0.5 mm \/ 1.46 x 1.65 x 0.63 ±0.02 inch\u003c\/p\u003e","brand":"Shelly","offers":[{"title":"Single","offer_id":57955522118006,"sku":"3800238070748","price":23.99,"currency_code":"GBP","in_stock":true},{"title":"Pack of 2","offer_id":57955524084086,"sku":"3800238070755","price":46.99,"currency_code":"GBP","in_stock":true},{"title":"Pack of 4","offer_id":57955525984630,"sku":"3800238070762","price":91.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/2396\/3613\/files\/df568ee789f8c690556446b014c99d308bf41570_Unknown_2_1.jpg?v=1779799426","url":"https:\/\/www.maplin.co.uk\/products\/shelly-2pm-gen4-wifi-zigbee-operated-dual-relay-switch-with-power-monitoring-cover-roller-control","provider":"Maplin","version":"1.0","type":"link"}
