Fine Offset Weather Station Binding: Discussion

Add-ons Bindings
151

The new GW1100 is in place, and it’s brilliant! Everything (or almost everything) is now working through the FineOffset binding. I’ve noticed a couple of things which I think might (?) be issues with the FineOffset binding, but none of these are deal-breakers, and all are at least as good as what I was getting with the ipObserver, as well as allowing me to access things like lightning which I couldn’t get through that binding.

Here are the issues I’ve observed since hooking up the GW1100 and migrating everything over to the FineOffset binding:

  1. rain-rate is defined in the Binding guide as Number:VolumetricFlowRate, however I don’t believe that’s correct. I don’t think openHAB actually includes a Number form which matches rain rate measurement, because that should be in length per unit of time (e.g. mm/hr): that isn’t the same as volume per unit of time (e.g. l/hr) which is what volumetric flow rate is, but since it’s always “per hour”, I think the choice made by ipObserver to define rain rate as Number:Length is correct. I’ve typed my linked item as Number, and that is giving me mm/hr (which is what I want), but that is not a QuantityType and wouldn’t handle a change in units being reported.

  2. A few parameters are displayed in WSView Plus and on the webpage when I access the GW1100 directly, but are not showing up as channels in the FineOffset weather station thing:

  • Feels Like/Heat Index
  • Wind chill
  • Outdoor dew point

According to the binding documentation, these channels should be supported, but they aren’t appearing. Any suggestions as to how to get them to show up?

Thanks again for this excellent binding - I’m so excited to have top quality weather data being fed in real-time into openHAB.
