This guide provides detailed steps to install a sensor on your Fluss+ device, enabling it to detect whether your gate, door, or barrier is open or closed. Depending on your motor, the Fluss+ can detect the state in one of two ways: by connecting directly to the motor’s status output wire, or by using a magnetic switch (Normally Open / Normally Closed).

Requirements

• A claimed Fluss+ Device.
  

• Device connected to Wi-Fi.

• Small screwdriver (flat head).

• Medium screwdriver (flat head).

• Sensor wiring (see Step 2).
  

Step-by-Step Guide

1. Disconnect the Fluss+ Device

If a Fluss+ is already connected, unscrew the wires connected to the motor. Make sure to note where each wire was connected before removing them.

Important: Always disconnect power to the motor/gate system before handling wires to avoid electrical hazards.

2. Choose your wiring method

There are two ways to wire the Fluss+ so it can detect your gate’s open/closed state. Choose the option that matches your motor and installation:

Option A — Direct Status Output Wire

If your motor has a dedicated status output terminal (most Centurion, E.T. Systems, DTS and similar gate motors), the Fluss+ sensor cable can be wired directly to the motor with no magnets required. 

→ Follow the Status output wire installation guide for Fluss+ for motor-specific wiring diagrams, then proceed to Step 3 (Setup the sensor display on the Fluss+ App) in this article.

Option B — Magnetic Switch (NO / NC wires)

If your motor does not provide a status output (for example, most garage doors and Gemini motors), or if you prefer a universal method, use the magnetic switch wires supplied in the sensor wire package. This method uses a magnet mounted on the gate and a switch mounted on a fixed surface to detect the open/closed state.

→ Follow the Magnetic switch wire installation guide for Fluss+ for motors that rely on door contact, then proceed to Step 3 (Setup the sensor display on the Fluss+ App) in this article.

3. Setup the sensor display on the Fluss+ App

This step applies to both wiring methods (Option A and Option B).

 1. Open the Fluss+ App and select ‘Devices’ on the bottom left.

 2. Select the device you are using for the sensor.

 3. Go to “Settings’”

4. Toggle “Sensor installed”

5. Select the wire type (NC or NO). 

If you used Option A (direct status output), select the wire type that matches your motor’s status output behaviour.

6. Select “Save” to save the device settings.

Seeing the status display

You should see the state update: a blue background indicates ‘Closed’, 

White background indicates ‘Open’.

Troubleshooting

The state never updates:

Double-check that both sensor wires are secured in their terminals and that the second wire is connected to a live voltage source.

The state is inverted (shows Closed when Open and vice versa):

You likely selected the wrong wire type in the app. Go back to Settings and switch between Normally Closed and Normally Open.
