- Tap the "+" icon in the top right corner of the app to add a new device.
- Select the IBS-M2 from the list of available devices.
- Follow the on-screen instructions in the app to connect the gateway to your Wi-Fi network. This typically involves entering your Wi-Fi password and confirming the device's status.
- Once connected, the Wi-Fi icon on the IBS-M2's LCD screen will become stable.
3.6 Pairing Sub-Devices
The IBS-M2 can connect to up to 9 INKBIRD Bluetooth and wireless sensors. To pair a sub-device:
- Ensure the sub-device is powered on and within range of the IBS-M2 gateway.
- In the INKBIRD app, navigate to the IBS-M2 device interface.
- Look for an option to "Add Sub-device" or "Scan for Devices".
- The app will scan for nearby compatible INKBIRD sensors. Select the sensor you wish to add from the discovered list.
- Follow any specific pairing instructions for the sub-device (e.g., pressing a button on the sensor).
- Once paired, the sub-device's readings will appear on the IBS-M2's LCD screen (in CH0 mode) and within the app.

4. Operation
4.1 Monitoring Temperature and Humidity
The IBS-M2 provides real-time temperature and humidity readings both on its LCD screen and through the INKBIRD app.
- On Device: The large LCD screen displays the current temperature and humidity. You can switch between Celsius and Fahrenheit using the button on the device.
- Via App: The INKBIRD app provides a comprehensive view of current readings, historical data (up to 1 year), and maximum/minimum/average values for all connected devices.

4.2 LCD Screen Display Modes
The IBS-M2's LCD screen can display information in different modes:
- Default Mode: Shows the gateway's internal temperature and humidity, along with the readings from a selected sub-device (e.g., "OUT 3").
- CH0 Mode: When selected, the screen will automatically cycle through the temperature and humidity readings of all connected sub-devices for 3 seconds each. This allows for quick overview of all sensors without needing the app.

4.3 Real-time Alerts and Notifications
You can set custom high and low temperature/humidity alert values for the IBS-M2 and its connected sub-devices through the INKBIRD app.
- In the app, select the device for which you want to set alerts.
- Navigate to the alert settings.
- Set your desired high and low thresholds for temperature and humidity.
- When the detected value exceeds or falls below the preset threshold, the associated device will emit an audible beep, and your smartphone will receive a push notification.
