After linking your Hub over Bluetooth in the Airthings Wave App you should now see your Hub at the top of the screen (boxed in orange below):

If you don't see your Hub at the top of your screen, try closing out the Airthings Wave App and reopening it to see if now appears. If you do not see it, try adding it once more by selecting the Add button at the top right of the app (circled in orange below):

If you're still having trouble connecting your Hub to your account, simply chat with us directly from the Airthings App under the support function or write us at support@airthings.com and we'll get back to ou as soon as possible.
