It may happen that you changed your WiFi/MQTT password and Glow Worm Luciferin device stops responding because it can't connect to the network anymore.

If this happens, you can reset your Glow Worm Luciferin device and set a new password in one of the following ways:

  1. Plug the ESP into your computer with a USB cable and reinstall the firmware using the Web Installer.

  2. Plug the ESP into your computer with a USB cable you can provision directly from Firefly Luciferin.

  3. If you are not able to connect an USB cable to the ESP because your ESP is now far from your PC you can do the following:

    • Power off the ESP device.
    • Luciferin will try to connect to the old network using the old password for 3 minutes, after 3 minutes Luciferin give up and turn on red the LEDs for 3 minutes (LEDs will stay on for 3 minutes and then turn off if no action is taken). You can now reboot the device using the reboot button placed on the ESP, if your ESP does not have a reboot button, simply unplug/plug the power.
    • Reboot the ESP three times. On every reboot Luciferin will turn the LEDs in a different color (Red, Green, Blu, Orange).
    • Once the LEDs are turned on in orange Luciferin will start a WiFi access point, connect to the Luciferin WiFi network using your PC or your phone.
    • Once connected to the Luciferin network, simply open a browser on http://192.168.4.1.
    • Your Luciferin device can now be reset with new settings.
