Is your sensor's name displaying but not the humidity & temperature icons in the My Valuable's list?

If so, this means your sensor has been un-linked. A sensor can currently only be linked to a single user's account. Refer to "Using the Blustream App with multiple phones" section.

To re-link your sensor, simply go to that sensor's Settings page and scroll down to select "Re-link a Blustream Sensor" and follow the on-screen prompts.
