Log files are deleted automatically if the Energy Monitoring Hub has successfully uploaded the log file to a database server
using the HTTP/Post protocol. If you do not configure the Energy Monitoring Hub to automatically push the log files to
your server, you must manually delete them. To delete log files, refer to the FTP method of downloading log files. One
step detailed in the FTP section is how to delete a log file from the Energy Monitoring Hub.
Uploading data to the Leviton Energy Manager website.
After the Energy Monitoring Hub has been configured and has logged some data, you will want to collect the data for
analysis. There are several ways of collecting the data from the Energy Monitoring Hub including the Leviton Energy
Manager hosted online service. Other methods are noted in the data collection FAQ. This section details configuring the
Energy Monitoring Hub for use with the Leviton Energy Manager website (*Note: model # A8812-001 is pre configured
with these settings).
Step 1:
First, use your browser to connect to the Energy Monitoring Hub. Select the Modbus/Setup section from the menu
on the left. In the field titled "Modbus Loop Name" enter a name for this Energy Monitoring Hub to uniquely identify it on
the LEM website. Because the LEM site can show multiple Energy Monitoring Hub devices, it is important to have a
descriptive name in this field.
Step 2:
Select the “Log File Data”, “Setup/Upload” menu option. The following features are available:
Energy Monitoring Hub Serial Number:
This is the serial number that uniquely identifies this Energy
Monitoring Hub. This number cannot be changed. When uploading data to the LEM website, this serial number is
used to identify the Energy Monitoring Hub to the LEM server.
Scheduled upload time:
This option allows you to control when the Energy Monitoring Hub will initiate the
upload process. You can select any hour of the day, and the Energy Monitoring Hub will select some time at
random within that hour to start the upload. The random feature allows multiple Energy Monitoring Hub devices to
share a single dialup account or phone line by not starting the dialout at the same time for all devices. If the Energy
Monitoring Hub is on a LAN connection (DSL, Cable Modem, T1, etc) an upload time of "hourly" may be
selected.
Upload data on alarm status change:
This
will cause the Energy Monitoring Hub to initiate the upload process if
any point on any Modbus device enters or leaves an alarm state. This allows the Energy Monitoring Hub to send
data when an alarm is detected, and will upload that information to the LEM website in a timely manner. The LEM
website will then send email notifications if necessary. If this option is disabled, the LEM website may not be able
to send notifications until the end of the day when the Energy Monitoring Hub calls in at its specified upload time.
Upload data on low disk alarm:
This feature will cause the Energy Monitoring Hub to attempt a data upload
immediately if the log file storage area is more than 75% full.
Allow remote Modbus device configuration:
If enabled, users may remotely configure alarms and other Modbus
device features on the LEM website. When the Energy Monitoring Hub uploads data to the LEM website, it will
also download any new configuration information as needed. Note: if configuration changes are made to the Energy
Monitoring Hub, those changes will be uploaded to the LEM site. If configuration changes are made at both the
Energy Monitoring Hub and the LEM website, the most recent changes will be used.
Target Address to upload data:
This is the website URL to upload data to. This should always be set to
"http://www.buildingmanageronline.com/upload.php" unless you are configuring the Energy Monitoring Hub to
send data to your own internal database server.
Password to upload data:
This password is used by the LEM webserver to verify the Energy Monitoring Hub
device authentication before accepting the uploaded data. You should select a password other than the default, and
make note of it for future reference.
Number of times to retry:
In the event of a failure (often due to dialup problems, busy signals, etc) this option
specifies the number of retries to attempt the upload again. If all retries fail, the Energy Monitoring Hub will wait
until the next scheduled upload time before trying again.
Time to wait before retry:
In the event of a failure, the Energy Monitoring Hub can be configured to wait for a
specified period of time before attempting another connection. This option specifies how long to wait before
retrying.
Step 3:
Contact the Leviton Technical Support department. Please have the
Energy Monitoring Hub serial number
and
password to upload data
handy. Your tech support representative will confirm your LEM account and will add the Energy
Monitoring Hub to one of your client databases.
Step 4:
Click the "Upload Data Now" button. Your data should be sent to the LEM webserver.
Step 5:
For more detailed information about the transfer process, use the Connection Test page in the Testing/Diags menu
on the Energy Monitoring Hub for a full report of the data upload progress.
