It seems the SmartWeather Station may not be configured properly and not pulling any data, therefore it got nothing to show in the SharpTools weather tile.
Can you open the SmartThings Classic app, find your Weather Tile in device list, click on the gear icon at right top and fill in your zip code info and save?
You may want to double check the SmartWeather Tile device’s installation steps just in case.
Once it starts to work, you should be able to see the Current States like this in SmartThings, and it should be displayed properly in SharpTools.io then.
