In addition to on\/off switching, it measures and reports real-time energy consumption through the eWeLink app, allowing users to monitor electricity usage and estimate costs directly from their smartphone.\u003c\/p\u003e\u003cp\u003eThe switch supports RF 433MHz control, enabling use with any compatible 433MHz remote in parallel with the app. It connects to Wi-Fi via IEEE 802.11 b\/g\/n at 2.4 GHz, works with Amazon Alexa, Google Assistant, and Samsung SmartThings, and includes overload protection. Timers — countdown, single, and scheduled — continue to operate even when the internet connection is unavailable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo independent output channels\u003c\/li\u003e\n\u003cli\u003eBuilt-in energy monitoring via eWeLink app\u003c\/li\u003e\n\u003cli\u003eRemote on\/off control from iOS and Android\u003c\/li\u003e\n\u003cli\u003eCountdown, single, and repeat timer scheduling\u003c\/li\u003e\n\u003cli\u003eOverload protection\u003c\/li\u003e\n\u003cli\u003eRF support: any 433MHz control\u003c\/li\u003e\n\u003cli\u003eWorks with Amazon Alexa, Google Assistant, and Samsung SmartThings\u003c\/li\u003e\n\u003cli\u003eWi-Fi IEEE 802.11 b\/g\/n 2.4 GHz (2400–2483.5 MHz)\u003c\/li\u003e\n\u003cli\u003eSecurity: WPA\/WPA2; Encryption: WEB\/TKIP\/AES\u003c\/li\u003e\n\u003cli\u003eEnclosure: PC V0, IP20 protection\u003c\/li\u003e\n\u003cli\u003eCertifications: CE\/FCC\/RoHS\/TUV\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eEnergy monitoring lets users quantify exact consumption per circuit and calculate electricity costs over time\u003c\/li\u003e\n\u003cli\u003eOverload protection automatically cuts power if the rated load is exceeded, protecting connected appliances\u003c\/li\u003e\n\u003cli\u003eRF 433MHz support means the switch can be operated by a physical remote even without a smartphone\u003c\/li\u003e\n\u003cli\u003eTUV certification adds independent safety verification beyond CE\/FCC\/RoHS\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Colour:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Material:\u003c\/strong\u003e PC V0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Rating:\u003c\/strong\u003e IP20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Systems:\u003c\/strong\u003e Android and iOS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoice Assistant Compatibility:\u003c\/strong\u003e Amazon Alexa, Google Assistant, Samsung SmartThings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWireless Frequency:\u003c\/strong\u003e IEEE 802.11 b\/g\/n 2.4 GHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWireless Standard:\u003c\/strong\u003e IEEE 802.11 b\/g\/n 2.4 GHz (2400–2483.5 MHz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecurity Mode:\u003c\/strong\u003e WPA\/WPA2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEncryption Mode:\u003c\/strong\u003e WEB\/TKIP\/AES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRF Support:\u003c\/strong\u003e Yes, any 433MHz control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e -10°C to 40°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage:\u003c\/strong\u003e AC 100–240V 50\/60Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e AC 100–240V 50\/60Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistive Load:\u003c\/strong\u003e 3300W\/15A total; 2200W\/10A per channel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Load per Channel:\u003c\/strong\u003e 10A\/2200W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Load:\u003c\/strong\u003e 10–240W\/1A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Range:\u003c\/strong\u003e 100–240V AC 50\/60Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e CE\/FCC\/RoHS\/TUV\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhy You'll Love It\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eEnergy cost tracking is displayed in the app — useful for identifying high-consumption appliances or circuits\u003c\/li\u003e\n\u003cli\u003eRF 433MHz compatibility provides a backup control method independent of internet connectivity\u003c\/li\u003e\n\u003cli\u003eTimers that work offline maintain schedules during router outages without any manual intervention\u003c\/li\u003e\n\u003cli\u003eTUV certification provides additional confidence for use in fixed electrical installations\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Other","offers":[{"title":"Default Title","offer_id":56578736783742,"sku":"545028","price":17.77,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2250\/3550\/files\/15675139719550.webp?v=1779616412","url":"https:\/\/lynk.gr\/en-eu\/products\/other-sonoff-dualr3-wi-fi-smart-switch-with-power-measuring","provider":"Lynk.gr","version":"1.0","type":"link"}
