SONOFF S61s Gen2 – Smart Plug with Energy Monitoring, Wi-Fi, Matter, white (S61STPF)

The S61 Smart Plug (S61STPF) is SONOFF’s Wi-Fi-enabled, Matter-compatible smart socket that allows remote control of connected devices and measurement of their energy consumption. Thanks to its simple Plug&Play design, it only needs to be plugged into a wall socket, then connected to a Wi-Fi network, and it is ready to use. It is an ideal choice for automating household devices such as lamps, coffee makers, or various small and large electrical appliances.

With its help, a traditional wall socket can be transformed into a smart plug outlet in one step. Using the eWeLink App on an iOS (Apple) or Android smartphone with internet access, you can remotely turn the socket on/off and set scheduled or one-time timers. Its energy monitoring function stores hourly power consumption data for up to 6 months in the eWeLink cloud, the consumption history graph can be viewed in the app, and the data can also be downloaded. Through the app, you can see real-time current (A), voltage (V), and power (W), as well as daily, previous day, and monthly consumption (kWh). The app also allows creating smart control rules, such as executing predefined actions if real-time power, daily consumption, or monthly consumption exceeds a specified value. (For example: if monthly consumption exceeds 39.99 kWh, it turns off the smart plug and sends a “Monthly 40 kWh consumption limit reached” notification to the smartphone.) The device also includes a physical push button, meaning the power can be switched on/off directly on the device. Remote access can also be shared with family members.

It is a perfect solution for smart control and energy monitoring of household appliances and plug-in lamps. With it, you can conveniently turn on devices remotely before arriving home and schedule automatic shutdown to save energy and costs. The smart plug maximum power: 3680W / 16A, so higher-power devices such as irons, washing machines, or electric heaters can also be controlled, taking maximum load into account.

The SONOFF S61 is not only convenient but also a safe solution: it features overload protection and reliable operation. Thanks to its compact size, it does not take up much space, so multiple devices can be used side by side in a power strip.
