Dave,
Just wanted to say a sincere "thank you" for the WUnderstation plugin. Very, very useful - especially now that meteohub seems to have slightly dubious support for the rfxcom interface these days. Nice to be able to pull in state from zwave sensors as well.
Just ran into a small issue that I thought I'd mention. I have a slightly dodgy Oregon Scientific barometer and wanted to remove barometer data from my WU uploads. Unfortunately, there's no way to do this with the UI. I ended up fixing the problem by stopping the WU plugin, editing the config manually to put "None" in the barometer variable field and restarting.
On the next rev, could you add "None" as a valid popup menu option? That way, you can remove a sensor from the WU publish after it's been configured. Niche, I know, but it might be useful to someone (especially if you're messing around with the less critical fields).
Cheers!
Scott...
