I raised my question about the ticker tape forecast not working when you go online to Weatherlink with Davis support, and received this terse and pretty unhelpful response:
Andrew,
Offline mode gives you forecast data on the ticker that is just not available in Online mode. To use a different Wifi, tap on the house, then the guy in the top right, then under "Console Configuration" tap on "Network".
Bit of a shame really in the age of advanced technology - that kind of detail in the forecast and being able to see all your detailed info and charts would have been great.
