Weatherlink may forward information to WU and CWOP, but since the original poster already has the WLIP he already has those abilities. He must want the ability now to upload to other weather services. WLL does not yet have those abilities.
There is a Github page on accessing the WLL internal API but it’s under development.
It appears the original poster has a hardware problem with his Ambient Weather Meteobridge ( Weatherbridge ). He can either have Ambient replace it or try one of the other products. The WLL may develop into a very comprehensive weather reporting tool but at present seems not to be fully developed or supported at least to the extent that the WiFi Logger, NanoSD and Meteobrige are now and the WLL will require a dedicated computer running full time to have 24-7 weather data uploads ( via programs as yet not available ) to any additional weather services, which is the biggest advantage of Weatherbridge, NANO & Nano SD and WiFi Logger.
The Meteobrige Pro is a great piece of equipment but much more costly than any of the others. It all depends on what features you want or need and how much you’re willing to pay to get them.
