Looking at your station it's only updating ever 5+ minutes . Is this the way it's suppose to be? Maybe that's the problem ?
No, that's not the case.
It's a Davis WS and uses Weatherlink which has a default of 15 minute updates.
To increase the rate to every 5 minutes, one needs to subscribe, which I have done.
There are a number of Davis Weatherlink stations within a few hundred km of me and which are shown on the map.
In addition, my daughter and son-in-law in Australia also have a weather station (not Davis) which reports every 5 minutes and theirs is shown on the map.
Apart from registering and reporting to WU, they did not do anything to make it appear on the map.
So I am a bit stumped!
