WiFi relay Sonoff world on - device overview and examples of use

The Sonoff World On relay, from the family of devices for wirelessly controlling the inclusion and disconnection of household loads via Wi-Fi from the network, will become a rather useful and convenient element of your home automation system. If you use a smartphone, you have Wi-Fi at home, and you also want to control the power of various network loads directly from your smartphone, even if you are away from home, then these Wi-Fi relays are just for you.

Just install the Sonoff relay near the outlet or switch (or even instead of the outlet or instead of the switch), and connect your household appliance in series through it with a 220 volt network. Then create a connection via the Internet, configure the connection with the relay via Wi-Fi, and control your household electrical appliances directly through the application from your smartphone. Let's take a closer look at the five Sonoff World On relay models.

Sonoff world on

This is the first relay in the Sonoff Wi-Fi Relay line. It is designed to control the power of any electrical appliance with power up to 2.2 kW from a standard household AC 220-240 V. The operating temperature range of the relay itself (a small plastic box in sight) is from -20 ° C to + 65 ° C, and the maximum permissible ambient humidity - 95%. The relay was originally intended for indoor use.

The relay can be connected to a wall outlet or to a switch; it is ideal for controlling the power of a table lamp, a refrigerator, a system of video surveillance cameras. The relay is able to work on a schedule with support for up to 8 timers.

All configuration and management are carried out through the Ewelink proprietary application in Russian, which is available for both iOS and Android. You can always see the status of the device in the application (whether it is on or off), and if you wish, remotely turn it on or off from the network. Fundamentally, the number of Sonoff World On devices that can be controlled from one smartphone is unlimited.

Sonoff world on th

This is the next model of Wi-Fi relays from the Sonoff World On family. This model is equipped with built-in humidity and temperature sensors. Thus, the device has the ability to not only work on 8 timers, it can also turn your loads on and off when the humidity or temperature reaches certain values ​​predefined in the Ewelink application.

The ability to control from a smartphone via the Internet still remains, but it is also supplemented by functions for setting up action algorithms with respect to temperature and humidity.

The model is ideal for managing the power of the boiler, air conditioner, convector, for controlling the climate in the greenhouse, to maintain the proper temperature of the house (for people, animals, or indoor plants), etc.

Of course, you can monitor the state of temperature and humidity in real time from a smartphone via the Internet. Technical specifications regarding switched load power are similar to Sonoff World On.

Sonoff world on rf

This model of Wi-Fi relay is able to work in the same way as Sonoff World On, its functionality and characteristics are the same, only in addition to the main function of power management of electrical appliances via Wi-Fi, the ability to control also from the remote control at a frequency of 433 MHz is added (one remote control is included with the relay). A model with a remote control is ideal for installing a guard at the post to control the gate, barrier at the entrance to the territory of a private house, etc.

Sonoff world on dual

The WiFi relay is similar in characteristics to the Sonoff World On, but it is designed to control two electrical appliances simultaneously, the maximum power of each of which is 2.2 kW. Devices can work in parallel, which doubles the possibilities in terms of maximum switched power. For example, it can be two oil heaters of 2 kW each.

Sonoff world on po

With this WiFi relay, you can not only control via Wi-Fi from the smartphone your devices with a maximum power of up to 2.2 kW per relay, turn them on and off, not only monitor their status online (the device is on or off) or quickly install timer control algorithm (maximum 8), but you can also collect statistics regarding the use of electricity by your devices.

You will get the opportunity in real time to see power and current data in the Ewelink application directly from your smartphone in the form of reports for the specified period. Convenient, isn't it. This relay will help to form an economical mode of using certain household electrical appliances, to establish material savings.

Ewelink app and management

The proprietary Ewelink application is easily located in the store, downloaded, and installed on a smartphone. It is enough to launch the application, then you will need to register in the system by phone number, enter a confirmation code, which will come via SMS, after which it will be possible to add devices.

The Sonoff relay has a button on its case, while holding it you need to wait until the indicator on the case starts to flash rapidly. Began to blink - you can find the module, enter its name, set the parameters of its Wi-Fi network. That's all.

Now it is possible to control the relay through a local Wi-Fi network, and if the owner is far from home, then via the Internet through the cloud. The application always reflects which of the relays are connected and which are not. Turned on and off relays can be seen in the application. The Sonoff World On RF model relay is seamlessly paired with 433 MHz interface remotes.

Whether the relay turns on / off with a button on it, through the remote control or via a smartphone, its new state is immediately reflected in the application. There is the possibility of sharing devices, for example, husband and wife, living in the same apartment, can control the same devices from both of their smartphones.
