Calculating Energy in Kilowatt-Hours
To calculate energy in kilowatt-hours, enter the Kilowatt-hours per Pulse into the
multiplier field in the Scaling Configuration pane. Enter 0 for the Offset.
If you are using a WattNode sensor, refer to WattNode Sensor Scale Factors for Energy
and find the Kilowatt-hours per pulse value for your CT Size and WattNode model.
If you are using another sensor, refer to the documentation that came with the sensor. See

System Alarms
There are two types of System Alarms.
 Device Alarms - allow you to monitor the state of the physical device.
 Communication Alarms - alert you when your device is not communicating
properly with HOBOlink.
In the Edit System Alarms page, you can enable both Device and Communication
alarms and set the notification method if the alarm is tripped. Upon receiving any system
alarm notification, you should verify your device's state to see if any action is required.
HOBOlink Printable Help
35
www.onsetcomp.com
Alarm Types
Missed Connection
This alarm indicates that your U30 missed a scheduled connection. When you enable the
Missed Connection alarm, you set the amount of time elapsed after a missed connection
to trigger the alarm ( Minimum: 10 minutes , Maximum: 10 days)
Every 5 minutes, HOBOlink checks to see if your device has surpassed its specified late
time. If it has, the alarm is tripped and the notification action is initiated (text, email or
both). You will be notified when the device successfully connects if you have checked
the Send on clear also box.
The Missed Connection alarm is reset when your device is launched or you edit the
Missed Connection alarm settings on the system alarms page. If your Missed Connection
alarm is reset, you will not receive a clear notification unless the device continues to be
late and trips the Missed Connection alarm again.
Battery Low
This alarm indicates that the battery level has dropped below 4.05 volts.
Memory Low
This alarm indicates that there is less than 12.5 % memory remaining.
Sensor Failure
This alarm indicates that a sensor has failed. This alarm is automatically enabled when
you enable a Sensor Alarm.
If any Device Alarm trips, all other Device Alarms are automatically disabled. After you
resolve the problem, you must re-enable any Device Alarms that you wish to have
enabled.
Clearing an Alarm
When a Device Alarm trips you can either re-enable it or leave it disabled and clear the
tripped alarm manually.
To clear an alarm without re-enabling it, select the Clear box and then click Save. The
Clear box only appears when the alarm is in a tripped state.
If you re-enable an alarm, all tripped alarms are automatically cleared.
IMPORTANT: When you re-enable the Memory Low or Sensor Failure alarms the
logger automatically re-launches.

Publishing Your Data to a Web Site
This feature allows you to publish your U30 Station data to Weather Underground
(wunderground.com).
1. If you do not have an account with Weather Underground, go to the following link
and create an account.
http://www.wunderground.com/wxstation/signup.html
2. To register your weather station, click Weather Stations at the top left corner of the
page.
3. Click the Register my Personal Weather Stations link under Upload Your Data
to Weather Undergound.
HOBOlink Printable Help
73
www.onsetcomp.com
4. Click the New Weather Station button.
5. Enter your information as required in the fields.
For information on setting up a weather station, see the Weather Underground
Wiki at:
http://wiki.wunderground.com/index.php/PWS_-_Personal_Weather_Stations
6. After you register the U30 with Weather Underground, record the Station ID.
IMPORTANT: When registering a new station with Weather Underground, there
is a wait time up to 30 minutes before the Station ID/Password can be validated by
HOBOlink due to constraints on the Weather Underground system. Wait at least
30 minutes before continuing to step 7.
7. Return to HOBOlink and go to the Settings page.
8. Check the box next to the device name to enable Web Publishing.
9. Enter the Station ID you received from Weather Underground and your Weather
Underground password.
10. Click Save. A URL will appear that links to your Weather Underground Station
History page.
HOBOlink Printable Help
74
www.onsetcomp.com
11. If you have Public Access enabled for the device, you can include this link on your
Weather Underground page. Return to your Weather Underground account and
click the Manage my Personal Weather Stations link under Upload Your Data to
Weather Underground.
12. Click the Edit button for the station.
13. Paste the HOBOlink URL into the Link URL field.
14. Add a title for the link in the Link Text field and click Submit.
Data from the U30 Station will begin appearing in Weather Underground within 5
minutes after the latest connection to HOBOlink.
Notes:
 If you see a message that the Weather Underground Station ID and Password are
incorrect when attempting to enable Web Publishing in HOBOlink, you may not
have waited long enough after registering the U30 Station with Weather
Underground. Newly registered stations in Weather Underground will not be
detected by HOBOlink for at least 30 minutes due to constraints on the Weather
Underground system. If you're certain you've entered the Station ID and Password
correctly, wait at least 30 minutes and then try enabling Web Publishing again.
 When the U30 Station connects to HOBOlink, data from HOBOlink is
automatically "pushed" to Weather Underground. This happens at every connection
interval (readout time). There may be up to a 15-minute delay from the time the
device calls in until the data appears in Weather Underground.
 HOBOlink pushes information from the device datafiles to the Weather
Underground Tabular Data only. HOBOlink does not control the Weather
Underground Summaries or Stickers. If you are using Summaries or Stickers, be
aware that there may be instances where the values do not match the HOBOlink
data due to limitations in Weather Underground.
 If the Weather Underground push service becomes temporarily unavailable, data
that was uploaded to HOBOlink while that service is unavailable will not appear in
Weather Underground immediately. Any data offloaded to HOBOlink while the
connection to Weather Underground is unavailable will be pushed when the service
comes back online.
 Do not use the same station ID for multiple U30 Stations because Weather
Underground is only able to display one data record per logging sample time.
Instead, register each of your U30 Stations in Weather Underground separately
creating individual station IDs for use in HOBOlink.
