From the WeatherLinkIP User Interface
- To access your WeatherLinkIP User Interface, aka WeatherLinkIP Configuration page, you'll need your devices' IP address. This IP address is assigned to your device from your router. If you use the WeatherLink software, you can find it there as well by going to Communications Port from the Setup drop-down menu. When You click the Find button, your DID and IP address will display.
- Enter your IP address (XXX.XXX.XXX.XXX) into the address bar of your web browser (i.e. Internet explorer, Chrome, etc) and hit enter.
- The WeatherLink User Interface page will appear, displaying WeatherLinkIP Configuration. Right below this you will see the Device ID along with other information, including the Firmware version. Please note: Changes to this page are not recommended unless you are familiar with TCP/IP configuration settings.
