How to connect eGauge meters to Wattics

This post illustrates how to enable the automated transmission of meter readings from your eGauge meters to the Wattics Energy Analytics Dashboard in five easy steps.

 

eGauge meters allow for automated data transmission via HTTP Post, meaning that once the meter is given internet access it can be configured to send data to Wattics without the need of additional hardware requirements such as a gateway device. The set up to configure the meter to automatically push data to Wattics is extremely easy and can be carried out in a few minutes following this step-by-step guide.

 


 

STEP 1: Request a unique URI from Wattics

Each meter you wish to connect to Wattics requires a unique URI, that will be used as a unique identifier for your meter. You must request the URI from Wattics via the eGauge URI Request Form. One of our agents will be in touch shortly after with your new URI to configure your meter.

 

STEP 2: Connect your eGauge meter to the Internet

 

NOTE: Your eGauge’s DEVICE-NAME is the device name printed on the front of your meter.

 

If your eGauge meter is already connected to the Internet (LED blinking on and off) and can be accessed through http://DEVICE-NAME.d.egauge.net/, move directly to Step 2.

If your eGauge meter is not yet connected to the Internet, plug your eGauge meter to the local LAN using a cat5 cable. Your eGauge meter will automatically setup Internet access by obtaining its local IP address and associated network information through a service called Dynamic Host Configuration Protocol (DHCP). You should see the LED blinking on and off a few moments after the meter is plugged in to the LAN. Your eGauge meter is now online and can be accessed through http://DEVICE-NAME.d.egauge.net/, where DEVICE-NAME is the specific name of your meter. You can now move to Step 2.

See http://egauge.net/support/#documentation for advanced static IP address configuration and troubleshooting.

 

STEP 3: Set the correct time zone for your meter

Access the eGauge configuration interface via the meter’s local IP address or through http://DEVICE-NAME.d.egauge.net/, replacing DEVICE-NAME with the name of your meter. Click on ‘Settings’ in the top right menu.

 


 

Click on ‘Date & Time’ in the left menu and make the necessary changes to ensure that the Current Time shown is your local time.

 


 

STEP 4: Configure your meter registers to select what measurements you want to send to Wattics Dashboard

eGauge meters can physically connect up to 12 x CTs to measure a portfolio of electrical parameters over four 3-phase circuits. As such, before pushing data to Wattics you need to configure the eGauge registers to reflect what the meter is specifically monitoring.

Click on ‘Installation’ in the left menu of the eGauge configuration interface to visualise and configure your data registers.

If your registers are already set from previous configuration, you will only need to update the registers’ name to match them with the Wattics register naming convention. The Wattics register naming convention must indeed be used to enable automated processing of data and visualisation within your Wattics dashboard. eGauge data registers must (re-)named with the following convention:

 

M<X>C<Y><Parameter Name>

where <X> is the meter number, <Y> the circuit number and <Parameter Name> the parameter name

 

  • Only change the register configuration if you know what you’re doing, refer to the eGauge configuration guide for full details.
  • The meter number should always be 1 unless the eGauge meter sends data on behalf of other meters (via Remote Devices and Import registers). In that case the Remote Devices’ Import Registers names should start with M2, M3, and so forth.
  • Active Power and Apparent Power Register names will also need to be updated in the formula used for the Reactive power calculation.
  • Your meter may only allow for 16-register configurations. In that case set up the 16 registers you are most interested in.

For example, the register name ‘M1C2‐Active Power Line 3’ will be used for the register storing the Active Power measurements for the Line 3 of your eGauge meter’s circuit number two.

 

If your registers must be configured from scratch, you can replicate the register configuration given below with the Wattics naming convention, where electrical parameters of one 3-phase circuit monitored by the eGauge meter are recorded.

Please note that not every set up will use the configuration in the example, and you may only select the registers and measurements you are interested in.

 

 

Helper 1: the formula for the Reactive Power calculation for your meter circuit 1 would be:

VAr($”M1C1-Active Power Line 1″,$”M1C1-Apparent Power Line 1*”)

VAr($”M1C1-Active Power Line 2″,$”M1C1-Apparent Power Line 2*”)

VAr($”M1C1-Active Power Line 3″,$”M1C1-Apparent Power Line 3*”)

 

Helper 2: If you want to send measurements for other circuits monitored by the meter (e.g. CTs 4 to 9), add registers with the same naming convention and update the register names to reflect the circuits monitored. A few examples are given below.

 


 

Helper 3: If you want your eGauge meter to send measurements on behalf of other eGauge meters, you need to first add the remote meters through the Remote Devices.

 


 

You can then import registers from the Remote Devices as shown below for two registers, paying attention to using the correct Wattics naming convention. Note that the registers name starts with M2 to indicate this is a different meter. Other meters will start with M3, M4 and so forth.

 

 

Enter your username and password to save your new settings, and wait for the eGauge to reboot.

 

STEP 5: Configure data upload to Wattics Dashboard

Click on ‘General Settings’ in the left menu and select ‘custom’ for the ‘Data Sharing’ parameter.

 


 

Set up your meter to automatically send data to Wattics cloud platform as follows:

  • Enter the unique ‘URI’ received from Wattics via email. If you have received multiple URI you must use one URI per meter.
  • Set Interval to 1 minute

 

Click on ‘Save’ to complete the configuration. Use your username and password if prompted. Your meter is now configured to upload new data readings to the Wattics platform every minute.

 

STEP 6: Get started with Wattics!

You will receive an email from Wattics as soon as the first meter readings are received.

This email will provide you a link to create a username and password to access your Wattics dashboard. From then on you will be able to log in to your Wattics Dashboard at http://dash.wattics.com and get started! You will be able to edit the name of your (new) organisation, site and meters from the Attributes tab, so that you can add multiple meters and manage them all together in one place.
