Wi-Fi plug


Wi-Fi plug is designed for remote control of power supply of connected electric equipment with power up to 3 kW. Plug has the function of power consumption control. The current load level of the connected appliance is displayed by changing the color of the LED ring of the Smart plug.

It is a receiver and allows you to connect external wireless sensors operating on RF 433 MHz or RF 868 MHz technology.

Available devices:

Water leak sensor RS-3225

Temperature and humidity sensor RC-3605

Door/window sensor RS-3215

Motorized ball valve RLP-3810

Motion sensor RS-3205

Light sensor RL-3201

4 in 1 sensor RMS-3209

Remote control panel RL-3120, RL-3126 and RL-3128

Glass break sensor RS-3250

Principle of operation

The devise is a relay for outdoor installation, closing and opening electric line. Any household appliance up to 3 kW can be plugged into the plug. The device supports the power consumption control function and displays the current load level of the connected device on the LED ring. The plug can be controlled not only locally but remotely by mobile application.
If the Wi-Fi network is not available, it will be possible to control the plug in the local network (i.e. the device and the phone shall be connected to the same Wi-Fi network) or physically, using the button located on the housing.

    Power consumption statistics

    Drag main menu shade up to get consumption report.

    Using filter you can see statistics per day, week and month. In order to have statistics by value, set up rates.


    You can set rates for each device with power consumption control function and monitor power expenses by value.

    Push notifications

    To use this function you should permit rubetek application to send push notifications. You can do it in your mobile phone settings.

    Sensor management

    Smart Plug plays the role of master device in house. The device collects the information on sensors operation, analyses data and immediately sends signal to your smart phone in case of alarm.

    It checks sensor functionality every 30 minutes (only sensors, operating at frequency 433MHz and 868 MHz).

    The plug supports the addition of sensors of both the old 433 MHz line and the new 868 MHz line. Find below comparative table of main sensor differences.
