Need help with your new purchase? You're in the right place!


You've purchased one of our products ... thank you very much and congratulations on owning a fine piece of technology!


We go to great lengths to ensure our products meet the highest levels of quality and usability, but we understand that sometimes things can get a little confusing. In those rare cases where something doesn't seem to be working the way it should, or if you need a little more info than the manual provides, please watch our video guides below.

important safety information

Our BLU TPMS External Sensors are installed on the end of your air valve stem, replacing your standard valve cap. These sensors require 3/4 “ clearance space when spinning on your wheel. You must check to ensure that these sensors will not come in contact with your brake calipers or any wheel components (especially if you have 90 degree, 45 degree or off-center/off-set air valve stems on your wheels). Sensors with improper clearance can be damaged and/or destroyed and will void product warranty. This can also be dangerous to riders and passengers as it could affect the condition of your air valve stem potentially resulting in loss of tire pressure.

frequently asked questions

  • Are the external sensors waterproof?

    Yes, as long as you make sure the battery door o-ring is properly seated when screwing the door back on.

  • Are the sensors compatible with Nitrogen?

    Yep! Both Internal and External sensors are compatible with Nitrogen-filled tires.

  • Can I use flat-repair compounds?

    No. Internal sensors have a very small hole which allows air into the device for pressure and temperature reading. Tire compounds such as 'fix-a-flat' or 'Ride-On' can clog this hole, possibly rendering the sensor useless. External sensors are exposed to the inside of the tire via their direct connection to the tire stem, therefore the same potential for damage exists. Use of these types of internal sealants will void sensor warranties.



  1. Double-check the following:
    1. If one or more sensors fails to connect to your phone during initial set-up,  you may have a dead or defective battery. Install new batteries and repeat set-up procedure.
    2. Ensure Bluetooth is activated on your phone. Our App uses this protocol to communicate with the TPMS sensors.
    3. Are the sensor batteries installed correctly? The positive side (+) should face up, away from the valve stem. There is an illustration in your User Manual showing this.
    4. GPS/Location Services: Our App requires Location Services to properly communicate with the TPMS sensors. Please make sure this setting is active. See item 6 below for more information.
  2. After inserting the sensor ID number into the App, the dialogue display does not show a value.
    1. The TPMS sensor only transmits data when the sensor is moving over 12 mph, is started after parked for over ten minutes, or the tire pressure difference at the moment is 30 kPa. When stationary, data will not be transmitted in order to save power. The TPMS sensor can be checked for normal operation with a tire pressure increase or decrease.
  3. App installation is completed, sensor ID settings are done, and the car is being driven, but no data is shown.
    1. Please restart the device and ensure Bluetooth is turned on.
  4. There is no alarm sound or voice warning.
    1. Ensure the device is not in silent mode or that the volume has not been turned all the way down.
  5. The alarm sounds for tire abnormality on screen but no voice warning is heard.
    1. Some Android devices do not support voice services. Please contact the device manufacturer for more information.
  6. My phone's battery is being drained faster than usual. What gives?
    1. After the BLU TPMS App has been downloaded and installed, please make sure that the GPS function is NOT set to be always on. This setting will be found in your Android or iOS device's system settings App.
    2. Set the GPS to 'While Using the App' to improve battery life.
