Method 3: WS-2902A - How to Send Weather Data to CWOP
As if that was not enough there is actually sort of a 3rd method which is like a hybrid of both prior methods to get the WS-2902A to publish to CWOP.
This 3rd method requires the ObserverIP and the WS-1000-BTH but instead of the Meteobridge (Weatherbridge) you do the whole network redirection mentioned in method 2 above. And so instead of capturing Weather Underground traffic from the WS-2902A display console you are capturing it from the ObserverIP over to the WeeWx computer. But there is more...don't stop reading yet.
This 3rd method actually has an advantage that may reduce some of the complexity of method 2. Since the ObserverIP can be modified to run an older version of its firmware you can then do the Weather Underground network redirection with just the ObserverIP. No need for router with complex custom firmware and no need for network expertise. This is because there is an older ObserverIP firmware that lets you change the IP address for the Weather Underground server. So instead of the ObserverIP sending data directly to Weather Underground you configure it with the IP address of your WeeWx computer and bingo, you have the data in WeeWx without needing to do the complex network redirection and without all that extra hardware. There are many old firmwares available to download for the ObserverIP. I don't know off hand exactly which older version is a good one that lets you modify the Weather Underground server IP address. This feature on the ObserverIP was blocked (removed) from the current versions.
Note: In case you were wondering...The WS-2902A does not have the capability of changing the the Weather Underground server IP address.
