Troubleshooting Guide

Look through the following table and locate an issue or problem you are experiencing in the left column and read possible solutions in the right column.

Relative pressure refers to sea-level equivalent temperature and should generally agree closely with the official station. If there is a disagreement, make sure you are not looking at absolute pressure, in particular, if your station is not near sea level. Also, check at different times due to occasional delays in updates to the official station.

·  Redo the pressure calibration procedure.

· The barometer is only accurate to + 0.09 inHg (3hPa) within the following relative pressure range: 8.86 to 32.48 inHg (300-1,100 hPa), which corresponds to an altitude of 29,527 ft. (9,000m) down to 2,500 ft. (750m) below sea level. At higher altitudes, you should expect a possible lesser accuracy and non-linearity effects in the error (the calibration offset only allows for a partially linear

correction).

Time is incorrect| · Make sure your time zone and DST(daylight savings time) setting is correct.
Data not| ·  Confirm your station ID is correct. The
reporting to Wunderground. com| station ID is all caps, and the most common issue is substituting a capital letter O for a 0 (zero) or vice versa. Please note the digit 0 can only occur in the last part of the station ID (which is a station number in a city).

Example, KAZPHOEN11, not KAZPH0EN11.

· Confirm that your password (also called: key) is correct. It is the password wunderground.com generated for your station ID. You can also verify it by logging in to wunderground.com and looking it up under “My Profile-My Devices.”

· If there’s a number “1” on the station key, try to input the lowercase of the letter “L” to replace it on the app.

· Make sure the date, time, and time zone are correct in the Device Setting. If it is incorrect, you may be reporting data for a point in the past or future and you may not see it where you expect it.

·  Check your router firewall settings. The gateway sends data via port 80. If you can access other websites using “http” (not to be confused with “https”) this setting will be OK.

No Wi-Fi connection, or gateway

configuration

| · Check for the Wi-Fi light on the gateway. If wireless connectivity is operational, the Wi-Fi light will be steady. Make sure you configured the correct SSID and password.
failed| Repeat the procedure as necessary to verify.

·  The gateway does not support so-called “captive Wi-Fi” networks. These are typical “guest” type networks where users have to agree to terms and conditions before being connected.

· Make sure your Wi-Fi supports 2.4 GHz signals (801 type B G, or N) because Wi-Fi that uses the 5 GHz spectrum is not supported. For router with dual- band, please disable the 5GHz band.

·  Turn off your mobile data/ cellular data.

· Ensure the DHCP mode is open Try alternative methods.

·  Method 1:

·  Power off the gateway.

·  Power on the gateway.

· Open the Wi-Fi network on your phone or computer, and connect to the hotspot of GW1200 -WIFI.
