Metar Light Setup Instructions

Important Notes

• The device will enter configuration mode after each power cycle. You don’t have to change anything—after 30 seconds it times out and uses the previously saved settings. If you do want to change a setting you only need to fill in those field(s) as any fields left blank will use the previously defined setting.
• The device may not work on guest Wi-Fi networks that require a captive portal (e.g., a web page after connecting). If your router/firewall has advanced security, you may need to allowlist/register the device MAC address. The MAC appears at the top of the configuration web page (see below).
• This device requires 2.4 GHz Wi-Fi. Some newer routers disable 2.4 GHz by default—enable it in your router settings.

Configuration Mode

1. Plug in your light. It enters configuration mode and flashes green for ~30 seconds.
2. While flashing green, open your phone or computer’s Wi-Fi settings and connect to the network named METAR. The light will then flash yellow.
3. Open a web browser on your phone or computer and go to http://192.168.4.1 to access the configuration page. Stop here if all you need is to take a screen shot of the configuration page for support purposes.
4. If this is the first time configuring your device select your Wi-Fi network (SSID) and enter the password. The network password is usually written on the back of your router. If you are just updating other settings there is no need to configure your network SSID/password again.
   Remember: passwords are case sensitive.
5. 2.4 GHz only: This device detects only 2.4 GHz networks. If yours doesn’t appear, enable 2.4 GHz on your router.
6. Enter the station identifier to report (e.g., KOSU). The station entered must receive FAA METAR reports.
7. Click SAVE. The light will restart.

Normal Operation

On power-up the light:

1. Flashes green (~30s) — configuration window
2. Flashes blue — connecting to Wi-Fi
3. Briefly glows orange — checks for firmware updates (remains orange while downloading; do not power off)
4. Flickers white — initial data fetch from FAA
5. Displays current station conditions; updates every 15 minutes

Colors: Green = VFR, Blue = MVFR, Red = IFR, Purple = LIFR.
Effects: Pulsing = winds > 25 kt; White flicker = lightning reported.

Press the button on the support shaft anytime to hear the report timestamp, station code, wind direction and speed (in knots) and current visibility (in statute miles). If not VFR, it will include the current cloud base. A touch sensor in the base can also trigger this (sensitivity may vary).

Troubleshooting

• Flashes blue then turns red: Wi-Fi connection failed and the unit restarts. Reboot your router and/or re-enter network settings. (Passwords are case sensitive.)
• Stuck in startup flicker: The station may not receive FAA METARs or was entered incorrectly. You can verify via SMS by texting metar <identifier> to 358782 (e.g., metar kosu). Early firmware required lowercase station IDs. During startup you can press the button to hear the configured station. To change it, power cycle and follow the setup steps.

Need help? Email support@metarlight.com. Include the device serial number and firmware version (shown in the configuration page header). The serial number is also on the sticker on the bottom of your light.
