Device Setup

This document outlines the step-by-step process for setting up and configuring the Yeti Gateway, including network connection, Modbus configuration, and cloud integration.

Prerequisites

  • A Yeti Gateway device
  • The device's MAC address (Provided with the device)
  • RS485 modbus supported device (This doc uses MFM-384 energy meter as example)
  • Either Wifi or Ethernet for Network Access
  • Cloud server credentials and certificate files (Provided with the device)

Part 1: Wiring Setup

This setup explains how to connect the Energy Meter to the Gateway. But This same A-to-A [ Red Wire ] and B-to-B [ Blue Wire ] wiring rule applies to any device (like other meters, PLCs, or sensors) that communicates using the RS485 Modbus standard.

  1. Find the RS485 ports:
    1. Look at the top section of the Energy Meter (MFM-384). You'll see two terminals labeled A and B.
    2. Look at the bottom section of the Yeti Gateway. You'll also see two terminals labeled A and B.
  2. Make the Two Connections:
    1. You need two wires. Do not mix up A and B!
    2. Use one wire to connect B on the Energy Meter to B on the Yeti Gateway.
    3. Use the second wire to connect A on the Energy Meter to A on the Yeti Gateway.
      • Rule: B must connect to B, and A must connect to A.
  3. Check for Mistakes (The Polarity Check):
    • Confirm that the A line is connected to A, and the B line is connected to B on both devices. Reversing these lines prevents proper communication.
  4. Power Up:
    • Connect the 12 V power supply to the Yeti Gateway and power up the energy meter to begin operation.

Part 2: Network Setup

  • Option A: Ethernet Setup

    • Connect a standard Ethernet cable from your network switch or router to the Ethernet port on the Yeti Gateway.

  • Option B: Wifi Setup

    1. Connect to the Access Point

      1. Power on the Yeti Gateway.
      2. On your computer or mobile device, open your WiFi settings.
      3. Connect to the network named YETI-PRO-XXXX.
        • replace XXXX with the last 4 digits of device's MAC address
      4. Captive Portal:
        • Ideally, a login page will open automatically.
        • If it does not, Go to your prefered web browser and go to http://192.168.192.168.

    2. Initial Login

      • Log in to the local configuration page using the following credentials:
        Username: yeti-pro-admin
  Password: The last 4 digits of the device's MAC address.

    3. Configure WiFi

      1. Once logged in, navigate to the WiFi Settings page.
      2. Enter your local network's SSID and Password.
      3. IP Configuration:
        • Dynamic IP: Ensure the Use DHCP box is checked.
        • Static IP: Uncheck Use DHCP and manually enter the IP Address, Gateway, and Netmask.
      4. Click Save WiFi Settings.
      5. Click Restart to apply the changes.

Part 3: Accessing the Web Interface

  1. After the device restarts, it will be connected to your local network. You can now access it using its hostname rather than the direct access point.
  2. Connect your computer/phone to the same local network as the Yeti Gateway.
  3. Open a web browser and navigate to http://yeti-pro-XXXX.local:
    • replace XXXX with the last 4 digits of device's MAC address
  4. Log in again using the same credentials: 
      Username: yeti-pro-admin
  Password: The last 4 digits of the device's MAC address.

Part 4: Modbus Configuration

  1. Configure Connection Settings

    1. Navigate to the Connection tab.

    2. Configure the RTU/TCP Settings.

      • Note: These settings must match the settings of your connected Modbus devices.

    3. Click Save RTU/TCP Settings.

  2. Add Modbus Devices

    1. Navigate to the Modbus tab.
    2. Click on a device block (e.g., Device 1) to open its settings.
    3. Enter the Slave ID for the specific hardware you are connecting.
    4. Click Add Register to configure data points.
    5. Enter the register details:
      • Parameter Name
      • Unit
      • Register Address
      • Register count
      • Data Type
      • Scale
    6. Click Add Register to save the specific data point.
    7. Repeat for all necessary registers.
    8. Click Back to Slave List.
    9. Finally, click Save Modbus Settings on the main Modbus page.

Part 5: Cloud Configuration

  1. Configure Server Settings

    1. Navigate to the Cloud tab.
    2. Enter the Server URL (e.g., mqtts://72.60.205.104).
    3. Enter the Port (e.g., 8883).
    4. Select the QoS Level.

  2. Upload Certificates

    1. You will need to copy and paste the content of your certificate files into the respective fields:
      • Root CA Certificate (PEM)
      • Device Certificate (PEM)
      • Device Private Key (PEM)

  3. Save and Restart

    1. Click Save Cloud Settings.
    2. Click Restart in the top menu to apply the new cloud configuration.

Part 6: Data Visualization

  1. To Visualize the device is sending data:
    1. Open a browser and navigate to the application server: https://www.garud.cloud
    2. Log in with your user credentials.
    3. On the dashboard, locate your device in the Your Devices list.
    4. Click the device name to view the Live Telemetry Data.
