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




Ball valves

Curtains and louvers

Garage gates

Sprinkler systems


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.

    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 supply → Flush-mounting→ Wi-Fi double switch relay → Wi-Fi double switch relay RE-3315 in the list of devices

    1. Press and hold the button on the case 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 mode

    Relay has two main operation modes: Switch and roller.
    In roller mode you can control electric actuator of gates, rolling shutters and louvers.

    Three types are available in switch mode:

    Light switch — relay closes and opens electric line, providing operation of the device with standard key switches.

    Pass-through light switch — relay’s state changes each time the switch is pressed.

    Button — allow controlling non-latching switches, e.g. button switches.


    The device shall be calibrated for correct operation in Roller mode.

    Go to control screen in application and press opening button. Wait for complete opening of curtains/gates or other equipment Press closing button and wait for complete closing. Your device has been calibrated.


    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. Statistics is displayed for the whole device, not divided per channels. 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.
