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:

    Connection of gate access gate controller to single-button switch

    Parallel connection to control button

    Control of strong load using contactor

    Connection of micro-wave Motion detector

    Connection of battery-operated sensor

    Allowable load

    Relay can be connected to any load, fulfilling the following specifications:

    1. Voltage up to 250 V;
    2. Switching current up to 13A.

    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 section Power supply → Flush-mounting→ Wi-Fi single switch relay with dry contact RE-3314

    1. Press and hold the button on housing for more than 6 sec. to put the relay to adding mode. LED shall start flashing.

    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 times per second, continue to set the device.

    Operation mode

    When you add unit in application define its normal conditions and operation mode.

    Selection of normal conditions:

    1. Normally closed;
    2. Normally open.

    Selection of dry contact operation mode:

    1. Impulse (Unit closes/opens contacts for 0.5 - 255 sec. and then automatically performs reverse action);
    2. Binary (Unit operates in Switch mode, closing/opening contacts).


    To switch 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

    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.


    Does the unit show the power consumption statistics of the devices connected to it?
    No, power consumption metering function is not provided in this relay.
    Will there be a conflict using the relay and the access gate/gate remote control?
    No, since information on gate/access gate status is available on the internal controller.
    Shall zero wire be available in socket box to install relay?
    Zero wire shall be available in socket box to install relay.
    Can I install the device myself without asking for help from a specialist?
    Only qualified specialist is allowed to install the device.
    Is it possible to create scenarios with relay?
    Yes. For example, you can create scenarios “Coming back home” that will be activated at opening of gates or access gates, connected to relay.
    Is it possible to control the relay when there is no internet?
    If you have previously set up timers for the relay in the app, they will be triggered regardless of Internet availability. Also it is possible to control the unit in local network, but not remotely.
