- แบรนด์ Sonoff รหัสสินค้า: SNOF-PWR-R2
Sonoff Pow R2 is a 15A WiFi smart light switch that allows you to remotely manage and control your appliances and monitor your home energy usage. The WiFi light switch works like a power monitor, which allows you to keep track of 99% accurate real-time current, voltage and power on your app.
Note: This smart power measure switch uses a similar enclosure as Sonoff TH16 - 15A WiFi RF Smart Switch. The hole on the enclosure is there, but PWR R2 DOES NOT support an additional sensor.
Check out the unboxing, wiring, setup of eWeLink and pairing, by Geek Street, also the work with Amazon Alexa and Google Home:
The power switch can protect your appliances from overload. What you need to do is to set threshold values for the current, voltage and power. It works like a kwh calculator that can measure electricity consumption for a specified period and a day. The eWeLink app provides 100 days recorded electricity usage data, which you can export to your phone storage. You can keep track of how much energy your appliances are consuming and estimate your running costs.
With the Pow R2 power monitoring switch, you can spend less on your electricity bill. The timers schedule your appliances automatically power on and off at a defined time. The scene lets your appliances work together in new ways, like setting the heater auto-off when the door light is off. This video shows how you can easily set up the Pow R2 Smart Switch with a light bulb and pair it with eWeLink App.
