Why isn't my logger appearing in the Recently Seen/In Range list on the HOBOs screen?
•
The logger may need new batteries. Symbols will appear on the logger LCD if the batteries have
enough voltage remaining and are installed properly.
•
The logger is not within range of the phone or tablet or something is obstructing the
communication. Move closer to the logger. The range for successful wireless communication is
approximately 30.5 m (100 ft) with full line-of-sight.
•
Make sure Bluetooth is enabled in your phone or tablet's settings.
•
Try disabling the "Show Only My Devices" setting if necessary.
I see my logger in the Recently Seen/In Range list, but I can't connect to it. What can I do?
•
Close HOBOmobile and then reopen it.
•
Power cycle the mobile device and try connecting again.

My logger is listed in the wrong group. How can I change that?

Connect to the logger, tap Configure, and then tap Group. Select a group for the logger or create a new
group. If you do not want the logger to be listed in any group, then remove it from all groups (no
checkmark should be displayed next to any group name). Tap Add to Favorites if you want the logger to
be in the Favorites group. Tap Start when you are done. The logger needs to be reconfigured for any
group changes to take effect.
I was setting up my logger and then I lost the connection. Will my logger still start?
If you did not tap Start before the connection was lost, then the logger will not start logging. Connect to
the logger again, finish choosing your settings, and then tap Start.
Can I check how much battery power is remaining or whether the logger is logging or stopped with
HOBOmobile instead of checking the logger LCD?
If your device is within range of the logger, you can view the logging status in the Recently Seen/In Range
List on the HOBOs screen. You can also connect to the logger and tap Full Status Details to see remaining
battery power and check configure settings.

How do I lock my logger so that no one else can configure it?

Connect to the logger and tap Logger Password. Enter a password up to 10 characters. The password will
then be required any time another mobile device attempts to connect to the logger. The device that
configured the logger, however, will automatically retain the password so you do not have to type in a
password each time that device connects to the logger.

How do I reset the password on a logger?

Simultaneously press both the Start/Stop button and the Alarm/Stats button on the top of the logger for 3
seconds or tap Reset to Factory Default on the Set Logger Password screen.

An alarm was tripped on the logger. How do I clear it?

Visual alarms are cleared based on the settings selected under "Maintain Visual Alarms Until" when
configuring the logger. This means the visual alarm will clear when the logger is reconfigured, when the
