Fluss+ Sensor Installation Guide: Gate & Door Open/Closed Detection

Sensor Installation Guide for Fluss+

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

  1. A claimed Fluss+ Device

  2. Device connected to Wi-Fi

  3. Small screwdriver (flat head)

  4. Medium screwdriver (flat head)

  5. 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.

AlertImportant: 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

Home screen with the Devices navigation item highlighted

2. Select the device you are using for the sensor

3. Go to Settings

4. Tap the Sensor Type picker

On the Settings page, tap the Sensor Type row. It defaults to No Sensor before installation.

5. Pick your sensor type

Select the option that matches the wiring you used in Step 2:

  • If you used Option A (Direct Status Output), pick Output Status.
  • If you used Option B with NC wires (magnet present = circuit closed), pick Normally Closed.
  • If you used Option B with NO wires (magnet present = circuit open), pick Normally Open.

6. Tap Save to save the device settings

The Save button is in the top-right corner of the page.

Seeing the status display

You should see the state update on the device's home-screen widget: a blue icon indicates Closed.

A white icon 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 sensor type in the app. Go back to Settings → Sensor Type and switch between Normally Closed and Normally Open (or to Output Status if your motor uses the status output wire).
