Yeah - I pull data into Hubitat via a UDP listener in node-red. But like the WeeWX integration, that also requires an additional computer to be setup (an RPi or whatever).
Victor had said that he'd look into the possibility of userland apps/drivers being able to bind arbitrary UDP ports in a future platform release. When that happens, a direct Hubitat integration that doesn't require another computer becomes feasible.
I don't believe that driver is still available. Also, if memory servers, it was also a print/export style module rather than a data loop driver. I released a data loop driver that might be of interest.
That would be valuable for many uses... 
Indeed!
It's still on his site. You just need login credentials, but there's no charge. It's called Weather Switch. But the code you've posted would do the trick too. Thanks for the pointer to it.
Personally, I gave up on Weewx. It was more to maintain than the value it brought to me. There's an HA integration for my Ambient Weather station I've used which allows me to actuate virtual switches in HE based on HA automations. It's cloud and does go off line from time to time though, so for anyone in need of near 100% reliability or reliable readings directly in HE, Weewx is for sure the way to go.
I built a custom driver that reads from WeeWx MQTT custom driver mqtt · weewx/weewx Wiki · GitHub , you know you can't have enough custom drivers. I posted the code here, You can plug in almost any topic that publishes JSON. It can be adopted to read a MQTT topic that just pushes values also. But I wanted the observations tha t provided luminance and some other values.
