5-step guide to install and connect your Wattwatchers device to Wattics energy management software
Step 1: Before connecting your Wattwatchers device
Ensure you have all the necessary equipment. You should have received the following to begin the installation process:
(1) Monitoring device(s) (Wattwatchers ‘Auditor’ energy meter),
(2) Current Transformers (CTs)
(3) Wiring Tails
You will need a mobile or device connected to the internet for the commissioning. (Commissioning is a series of site tests and checks to confirm that the metering systems are accurately recording the flows of electricity at the defined metering point.)
A clamp meter could be useful to double-check that the meter reading corresponds to what the clamp meter says to configure the Auditor (energy meter) and capture information about the installation.
You need about 35mm wide space available on the DIN rail. If there is no space, additional DIN rails may be mounted in the meter cabinet or you’ll need an external enclosure. Ensure that there is space to clamp the current transformers and that they are wide enough to accommodate the cable size, meaning that the cable diameter should fit within the width of the CT opening.
Ensure there is a way to isolate the Auditor (energy meter) voltage inputs. You need to power the meter with an existing or new circuit breaker (depending on the regulations in your jurisdiction). If you are using as single-phase monitoring, you can also power up the meter through a wall socket. A breaker is not included in the Auditor (energy meter) package.
Step 2: Connect your device
The following configurations are for businesses or homes that are either multi-phase or single-phase powered. The voltage connections are labeled P1, P2, P3, N.
Wattwatchers meter view from the top
Three-phase voltage connections -> Use the three-phase wiring tails provided with your meter to connect voltage phases to P1, P2, and P3. Connect neutral to N.
Single-phase voltage connections -> Use the three-phase wiring tails provided with your meter to connect P1, P2 & P3 to the same phase. Connect neutral to N.
Current transformer connections
- For grid monitoring: The arrow at the base of the CT should point away from the grid
- For solar monitoring: The arrow at the base of the CT should point away from the inverter
- For load monitoring: The arrow should point toward the load
Different-sized CTs can be used on one device, in sets of three eg. channels 1-3, 60 Amps; channels 4-6, 400 Amps. Contact us for the selection of CTs.
CT sizes can be changed using the onboarding tool in the next step.
The Wattwatchers meter accepts 6 connected CTs, for example, to monitor 2x three-phase loads. The CT connections are labelled: ≡,6+,5+,4+,≡,3+,2+,1+
The white wires connect to terminals labeled “≡” – three wires in each terminal. The pink wires connect to the terminals labeled “+”. The CTs and Voltage phases should match as depicted below:
Step 3: Commission your meter to Wattics with the onboarding tool
The Wattwatchers online onboarding tool (https://onboarding.wattwatchers.com.au/) works with your mobile and collects the installation details for each site including device serial number, circuit names, and CT size.
Contact Wattics to get your credentials for the online onboarding tool. Log onto the onboarding tool and work through the steps to configure your device(s) for the installation site.
Step 4: Check meter-status indication lights
After the installation is completed successfully, all three green lights on the front of the meter should be lit green. The table below shows the meaning of the lights.
If there is an issue, the diagram below can help:
For more information on the installation of your Wattwatchers device, refer to the following guide or contact Wattwattchers directly at firstname.lastname@example.org
Step 5: Connect your Wattwatchers device to Wattics
The next step is to register the Wattwatchers meter channels in the Wattics dashboard. This action enables you to stream the readings from your Wattwatchers device(s) directly to the Wattics energy analytics platform. It is really just a matter of following a few simple steps which are explained in the next section.
Step 1: Log in to your Wattics dashboard
Step 2: Visit the integrations page available from the admin tab
Step 3: Open the Wattwatchers integration settings page
Step 4: Click on New Wattwatchers API key
Step 5: Enter your Wattwatchers API key (1) and provide a name for it (2). Then save (3).
Note: Get in touch with Wattwatchers Technical Support to obtain your API Key in case you don’t have it yet.
Step 6: Add your Wattwatchers device to the dashboard
Once your API key is registered, you are ready to add your Wattwatchers device to your Wattics dashboard.
In order to add a Wattwatchers data point to your dashboard, the procedure is the same one used to create all the other metered points. Click here if you need a refresh on how to do it. Once you have the data point creation webpage open, please read the following line carefully:
- You have to select Wattwatchers from the Data Point Type drop-down list.
- The Devices drop-down list contains all the devices you have access to using all the Wattwatchers API Keys associated with your Wattics account.
- The Group drop-down list contains all the groups that were pre-configured on the particular device you have selected when it was installed. For specifics about the circuit each current transformer (CT) is monitoring, please refer to the Details section located at the bottom of the page.
- For each group, energy readings are available as Net, Import & Export. Please select the option that best suits your project from the Energy Metering drop-down list.
- The Process sampling rate is set at 5 minutes by default. Feel free to adjust it to a different value.
- The new data point will be populated with historical data as soon as it is created. Once all the available historical data is retrieved, it will go live.
- Ensure the site address is accurate. It will be used to determine the local time where your device is installed.
- The current Wattwatchers + Wattics integration gives you access to Active Energy (kWh), Active Power (kW), Apparent Power (kVA) and Reactive Power (kVAr) readings.
