Ecowitt GW1200 Wi-Fi Hub Gateway User Manual

1. Introduction

Thank you for purchasing this GW1200 Wi-Fi Weather Station Gateway. This device features built-in temperature, humidity, and barometric sensors, and is designed to handle data from all Ecowitt sensors. Its firmware can be upgraded to support future sensors, making it a highly flexible component of the Ecowitt ecosystem. For optimal product performance, please read this manual thoroughly and keep it for future reference.

2. Package List

The following items are included in your GW1200 package:

Note: The gateway must be powered via a USB (2.0 or later) port. Use the included USB extension cable to position the gateway away from AC adapters, which can be heat and EMI sources. This improves radio signal reception and indoor temperature/humidity accuracy.

3. Setup

3.1 Power Up

Before powering up, prepare a power adapter with a USB port. Connect the GW1200 using the USB extension cable. DO NOT plug the GW1200 directly into a power outlet.

3.2 Install Ecowitt App

Download the free Ecowitt App from the App Store or Google Play Store. You can also scan the QR code below to download.

3.3 Gateway Wi-Fi Configuration

To connect your GW1200 to your Wi-Fi network, you will need your Wi-Fi network name (SSID) and password. Ensure your mobile device is connected to the same Wi-Fi network.

3.3.1 Through Ecowitt App

1. Open the Ecowitt App.
2. Click "Add New Weather Station".
3. Select the GW1200 icon and choose "WiFi Provisioning".

4. Operating Instructions

4.1 View and Size

4.2 Features

• Built-in 3-in-1 temperature, humidity, and barometric probe sensor.
• Collects data from various supported wireless sensors.
• Supports additional/optional sensors (refer to Section 4.3 for a detailed list).
• Calculates dew point for outdoor sensors (with cloud upload).
• Uploads sensor data to cloud weather services: ecowitt.net (default), wunderground.com, weathercloud.net, wow.metoffice.gov.uk, and customized servers.
• Mobile application (Ecowitt APP) for viewing live data, managing sensor calibration, selecting sensors, and rainfall settings.
• Data storage service on Ecowitt server: https://ecowitt.net.

Note: Ecowitt.net hosts all supported sensors. Other data hosting services like Wunderground.com may only accept outdoor sensor data and might not display all sensor types.

4.3 Elements Explanation

4.4 LED Indicators

• RF (Blue): Indicates RF communication status.
  • Flash (each): One packet of RF data received from a sensor.
  • Off (steady): No RF data received.
• Wi-Fi (Red): Indicates Wi-Fi connection status.
  • Off: Wi-Fi connection to router failed.
  • On: GW1200 provisioned to router and data successfully sent to a cloud hosting service.
  • Flash slowly: GW1200 connected to router but failed to publish data to cloud weather services.
  • Flash rapidly: GW1200 is in factory reset default state, not configured for router or weather server.

4.5 Button Function

The black button on the GW1200 is used for reset functions.

• Reset Mode: Hold the black button for approximately 5 seconds to reset the gateway to its factory default state. This will erase all history data, Wi-Fi settings, calibration, and sensor labeling, requiring them to be set up again.

4.6 Manage Sensors

To pair optional sensors with the GW1200:

1. Place the optional sensor next to the gateway.
2. Power on the sensor and wait 1-2 minutes.
3. Check if the GW1200 automatically picks up and displays sensor data in the app.
4. If data is not received, ensure the phone and GW1200 are on the same Wi-Fi network. Open the Ecowitt App, find "Sensor ID", and go to the "Edit Gateway" page.
5. On the "Edit Gateway" page, find the sensor you wish to pair, select its ID number box, and register it.
6. Upon successful registration, return to the main interface to check the data.
7. If you know the exact sensor ID and want the GW1200 to pair only that sensor, enter the sensor ID and save the change.

To disable (stop) a sensor:

If you have multiple gateways receiving data from multiple transmitters, or if you want to switch which transmitter's data the GW1200 receives:

1. Tap the editing icon for the sensor.
2. Manually input the sensor ID of the transmitter you want to receive data from and set its status to "Enabled".
3. Tap "Save".

To stop receiving data from an unwanted transmitter:

1. Tap the editing icon.
2. Manually input the default sensor ID to lock onto this sensor.
3. Set its status to "Disabled".
4. Tap "Save" to apply the lock immediately.

4.7 Add a Subdevice

The GW1200 supports smart control devices like WFC01 and AC1100. Connection methods are demonstrated in the app's subdevice section.

4.8 Upload Data to Server

After Wi-Fi configuration, data can be uploaded to various weather station servers:

• ecowitt.net (Default)
• wunderground.com
• weathercloud.net
• wow.metoffice.gov.uk
• Customized servers

To manage upload servers: Ensure your mobile phone and GW1200 are on the same Wi-Fi. In the Ecowitt App, go to "..." (top right corner) > "Others" > "DIY Upload Servers".

4.9 Historical Data Export and Clear

The GW1200 does not have internal memory for data storage. Once Wi-Fi is configured, you can log in to Ecowitt.net to export data in CSV format.

1. Choose the desired time period for data.
2. Click "Export".
3. The file will download automatically.

Note on Data Retention: Data with a query period of days/24 hours is retained for 3 months. Weekly data is retained for 1 year. Monthly data is retained for 2 years. Yearly data is retained for 4 years.

To clear history data: In the Ecowitt App, navigate to "menu" > "devices" > "..." button to clear history data.

4.10 Calibration

If you have a relatively accurate weather station for comparison, you can calibrate your GW1200's sensors:

1. Ensure your mobile device is connected to the same Wi-Fi network.
2. Click "..." on the top right corner of the app and choose "Calibration".
3. For a specific parameter (e.g., Indoor temperature), calculate the offset between your accurate weather station and the Ecowitt sensor.
4. Fill in the calculated offset and click "Save".

4.11 Rain Settings

If you have multiple rainfall sensors, you can set the priority for which sensor's data is displayed. You can choose between a Traditional Rain Gauge or a Piezoelectric Rain Gauge.

You can also set the initial values for Rain Totals (current year, month, or week). This is useful when migrating from another system or correcting incorrect values.

1. Ensure your mobile device is connected to the same Wi-Fi network.
2. Click "..." on the top right corner and choose "Rain Totals".
3. Fill in the correct Rainfall value and click "Save".

4.12 Unit and Other Settings

In the Ecowitt App, click "Settings" to select desired units for various parameters and access other settings.

4.13 Firmware Upgrade

Via Web Page: If "Automatically upgrade firmware" is selected on the web page (192.168.4.1), the GW1200 will reboot automatically when new firmware is available (checked every 24 hours).

Via Ecowitt App: Open the Ecowitt App, go to "Weather Station" > "..." (open the edit gateway page). Tap the firmware version number to upgrade if a new version is available. The GW1200 will reboot after the upgrade.

5. Maintenance

• Cleaning: Keep the GW1200 unit clean and free from dust. Use a soft, dry cloth for cleaning.
• Firmware Updates: Regularly check for and install firmware updates via the Ecowitt App or web interface to ensure optimal performance and compatibility with new sensors.
