Ooh, any chance your work here is worth reviving? I’ve been frustrated with the OWM data accuracy in my area and was considering attempting to hack on a binding for NOAA. Sounds like you got pretty far, and it could be a good starting place. I have no experience writing for openhab. Otherwise I was considering basing an implementation off of the OWM binding codebase
Have at it if you are interested. OWM has been accurate enough for my purposes so I’ve not gone any farther than posted here. But NOAA is kind of the root source for weather data for a lot of the other services anyway so it makes sense to go to the source.
Just make sure to review NOAA’s website because their APIs may have changed since the last time I looked into it.
