Onset support FAQ

Fesili masani e uiga i tusi lesona, resitalaina, ma lagolago mo lenei ituaiga.

  • How do I connect to my HOBO MX series logger?

    Download the HOBOconnect app (formerly HOBOmobile) on your iOS or Android device. Enable Bluetooth, ensure the logger is awake (press the button if needed), and tap the logger in the app's 'In Range' list to connect.

  • What requires the HOBOware software?

    HOBOware is generally required for launching and reading out data from Onset's USB-based data loggers. The software is available for download on the Onset webnofoaga.

  • How do I change the batteries in my HOBO data logger?

    For most pendant or compact loggers, open the battery compartment (often by unscrewing an end cap or removing a back plate), remove the old batteries, and insert new ones observing the polarity. Ensure o-rings are free of debris before resealing to maintain water resistance.

  • How do I reset the password on a HOBO MX logger?

    On compatible MX loggers, press both the Start/Stop button and the Alarm/Stats button simultaneously for 3 seconds to reset the password.

  • Can Onset loggers be used underwater?

    Many HOBO loggers, such as the U20 Water Level or Pendant series, are waterproof and designed for underwater deployment. However, models like the MX1101 are for indoor use only. Always check the environmental rating (IP rating) in your manual.
