# Connect Your Energy Meters to watt.ma

> Learn how to add a new energy meter to watt.ma, configure Modbus/TCP or smart meter integration, and verify that readings are flowing in.

Connecting your meters is the first step to seeing real-time energy data in watt.ma. Once a meter is linked, watt.ma starts receiving readings automatically so you can monitor consumption, run reports, and trigger alerts. This guide walks you through adding a meter and confirming the connection.

<Steps>
  <Step title="Open the Meters section">
    Log in to watt.ma and select **Monitoring** from the main navigation. Click **Meters** to open the meter management page.
  </Step>

  <Step title="Add a new meter">
    Click **Add Meter**. Enter a descriptive name, such as "Main Incomer - Factory A", and choose the facility it belongs to.
  </Step>

  <Step title="Choose the integration type">
    Select the protocol your meter supports:

    * **Modbus/TCP** — Enter the meter's IP address, port (usually 502), and Modbus unit ID.
    * **Smart meter integration** — Pick your meter brand from the list and enter the serial number or API credentials provided by the manufacturer.
  </Step>

  <Step title="Map channels">
    Define the channels you want to track, such as "Phase L1", "HVAC Floor 2", or "Production Line 3". Each channel will appear as a separate data stream in dashboards and reports.
  </Step>

  <Step title="Verify the connection">
    Click **Test Connection**. watt.ma attempts to reach the meter and read a sample register. If the test succeeds, click **Save** to start continuous data collection. If it fails, check the network settings and credentials, then retry.
  </Step>
</Steps>

<Note>
  watt.ma supports a wide range of meter brands, including Schneider Electric, Siemens, ABB, and Socomec. If your model is not listed, contact support with the make and model number so we can add compatibility.
</Note>

After the meter is saved, readings typically appear on the dashboard within one to two minutes. If no data shows up after five minutes, review the connection test or check that the meter is online on your local network.
