1) What is this device?

EMDR-Lite is a bilateral stimulation device: light “runs” along an LED strip. Control is intentionally simple — a button and a potentiometer.

It can be controlled via the EMDR-Lite app (Bluetooth) and via the EMDR-Lite Platform server (Wi‑Fi).

2) Controls and indicators

Button

  • Short press: if the device is on and waiting — starts movement;
  • if movement is already running — stops it and returns the light to the center;
  • if the device is “sleeping” — wakes up;

Potentiometer

  • In normal mode it changes the movement speed.
  • While holding the button, the potentiometer selects the color.

LEDs and strip

  • The strip is the main indicator: it shows movement, modes, and animations.
  • Wi‑Fi indicator (yellow):
    • solid — Wi‑Fi connected;
    • blinking — network configured but not connected;
    • off — Wi‑Fi is disabled or not configured.
  • Bluetooth indicator (blue) shows Bluetooth connection state:
    • solid — the EMDR-Lite app is connected;
    • off — Bluetooth is disabled.

Device mode indication on the strip

  • Blue — Bluetooth pairing.
  • Yellow — Wi‑Fi setup.

3) Daily use

Starting and stopping stimulation

  1. Press the button. If the device was asleep, press again — this is normal behavior.
  2. The strip will start moving.
  3. Press the button again — movement stops and the light smoothly returns to the center.

Sleep (power saving)

  • If the device is not used for a while, it automatically enters sleep.
  • The first button press wakes the device up.

4) Wi‑Fi setup

How to enter Wi‑Fi setup mode

  1. Hold the button.
  2. Apply power without releasing the button.
  3. The device will enter Wi‑Fi setup mode — a yellow color will appear on the strip.

Connect to the device network

  1. On your phone or laptop, open the list of Wi‑Fi networks.
  2. Connect to the device network (Network name: EMDR-Lite Password: therapist).
  3. A setup page will open. If it doesn’t open automatically, open a browser and go to 192.168.4.1

SSID: EMDR-Lite
Password: therapist

If the setup page doesn’t open automatically, open a browser and enter 192.168.4.1

Choose your home network

  1. In the portal, select your Wi‑Fi network from the list.
  2. Enter the password.
  3. Save.

After saving, the device will try to connect to the selected network.

Wi‑Fi indicator:

  • blinks while connecting;
  • solid when the connection is successful.

5) Bluetooth

How to enter Bluetooth pairing mode?

Hold the button for more than 8 seconds — a blue animation will appear on the strip.

After that, you can connect from the EMDR-Lite app (coming soon).

6) FAQ

Wi‑Fi won’t connect (SERVICE LED keeps blinking). What should I do?

  • Check the Wi‑Fi password.
  • Enter Wi‑Fi pairing (hold the button while powering on) and configure Wi‑Fi again.

I want to change the Wi‑Fi network but the old one is already saved.

  • Just enter Wi‑Fi setup mode again and select a new network — the old settings will be replaced.

How do I know I’m in Wi‑Fi setup mode?

  • You'll see a yellow animation on the strip and a Wi‑Fi network named EMDR-Lite will appear.
