It is a receiver and allows you to connect external wireless sensors operating on 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 panels RL-3120, RL-3126 and RL-3128

Smart button RL-3337

Principle of operation

The device is a flush-mounted relay that closes and opens an electrical circuit. Any device up to 3kW can be connected to relay.

Relay supports the power consumption monitoring function that allows monitoring instantaneous power and power consumption for a specific period in a mobile app.


Control illumination and electric appliances using mobile application.
Set on/off timers as per schedule for specified time
Use voice control
Add the device in HomeKit and use voice control at Apple-based devices
Analyze statistics of power consumption on-line in kW and by value
Connect up to 64 sensors, operating at frequency 868 MHz
Create scenarios to control devices in rubetek system

What devices can be connected?

Underfloor heating





All terminals (including S and Sx) of relay are energized and cause an electric shock hazard. Touching terminals of the connected relay can cause electric shock.

Only qualified specialist is allowed to install the device.

Be sure that power line is de-energized before installation. During electrical installation, do not allow any contact between the conductor strands and the relay terminals. Use swage, if necessary. Conductors shall be securely fixed in terminals.

Relay shall be places within operating range of stable Wi-Fi network.


Zero wire shall be available in socket box to install relay.

Hookup relay according to wiring diagrams, provided in manual.

Do not connect a load that exceeds the recommended values to the device.

It can be installed on horizontal and vertical surface.

Relay can be installed in standard installation box (socket box)

It is recommended to use increased depth socket box.

It can be installed in electric junction boxes, hide behind luminaires, stretched and suspended ceilings.

    Connection of the relay

    Ensure that electrical line to which you are going to connect relay is de-energized. Follow safety procedure!

    Connect relay according to diagrams, provided below:

    Single-button switch

    Installation behind ceiling or in junction box

    Control of dimmer, temperature controller

    Lighting by two one-way two-button switches

    Lighting by three one-way two-button switches

    Lighting by two one-way switches in junction box

    Lighting by three one-way switches in junction box

    Control of 24 V devices

    Mobile app

    Download and install rubetek application from App Store or Google Play.
    You can use QR-code.
    Create an account and confirm your mobile number to use the application.

    Adding to application

    1. Open rubetek application.
    2. Press '+' in top right angle of the main screen
    3. Select 'Add Device'

    1. Select Power → Flush-mounting→ Single switch relay → Wi-Fi single switch relay RE-3313 in the list of devices

    1. Press and hold the button on the housing max. 6 sec. If activation is successful LED will flash blue.

    If LED flashes with speed about 1.5 times per second, press service button once again and hold it longer. If flashing speed is about 6 timers per second, continue to set the device.

    Operation modes

    Relay has two main operation modes:

    1. Standard switch — restore the condition from app settings after power disconnection
    2. Standard switch — restore the condition as per physical switch after power disconnection
    3. Inverse switch — restore previous conditions after power disconnection
    4. Button — control of non-latching switch.


    To turn the relay on/off, a single press on the tile of the device is sufficient.

  • With a one scale division signal, we do not guarantee stable operation of the security system. Move the device to improve signal quality.

    It is possible Wi-Fi network only within local network, i.e. Your mobile phone shall be connected to current Wi-Fi network to which the device is connected

    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.

    Sensor management

    Relay 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.


    Relay supports up to 10 timers for switching on and 10 timers for switching off. The will be in operation regardless of the availability of the Internet. Got to control shade and press its tile on the main control screen to set timers.


    Combine devices of one type in groups and control them simultaneously. In order to create new group, press '+' in top upper angle of the main screen and select Create group.

    Push notifications

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