I had read something like this previously and have tried this already. When I click on the wrench Icon It takes me to Device Info. I see a few settings like time zone, station location, county, lat/long, a box to enter notes, a drop down box to select device use (home, school, farm, etc.) station model, which I have selected to match my vantage pro 2 wireless, and then a drop down to select public or private weatherlink network. I have nothing on this page at all regarding sensor ID's. I cant find anything regarding sensor ID's at all on here.
Just for what its worth, All of my data is being sent to weatherlink using the Weather IP plugged into the vantage pro 2 console.
