How to connect a Gree air conditioner to Wi-Fi: 5 proven methods + troubleshooting

Air conditioners Gree Wi-Fi-enabled devices allow you to remotely control your climate control system, set schedules, and integrate with smart home systems. However, connecting to the network often raises questions: the app may not detect the device, the router may not assign an IP address, or the Wi-Fi indicator on the remote may flash with an error. In this article, we'll cover all the current connection methods—from standard setup via G+ app to manual methods for older models.

We will pay special attention to typical problems: why the air conditioner Gree It won't connect to 5 GHz, how to reset Wi-Fi settings if you've forgotten the password, and what to do if the indicator on the remote is red. We'll also provide a compatibility table of models with different Wi-Fi standards (802.11b/g/n/ac) and routers from TP-Link, ASUS And Keenetic.

If you have already tried to connect and received an error (for example, E1, E2 or WIFI-FAIL), skip the introductory part and go straight to section with solutionsFor air conditioner owners Gree G10, U-Crown or Lomo Separate instructions have been added taking into account the specific features of their Wi-Fi modules.

Network and hardware requirements before connecting

Before you begin setup, please check if your network meets the minimum requirements. GreeAir conditioners of this brand work only with networks 2.4 GHz (5 GHz is not supported by any model for 2026.) Also required:

  • 📶 Signal strength: not lower than -70 dBm (check in the router settings or through applications like Wi-Fi Analyzer).
  • 🔒 Encryption type: only WPA2-PSK (AES). WPA3 And WEP are not supported.
  • 📡 Wi-Fi channel: Automatic or fixed (1–11). Channels 12–14 may not work in some regions.
  • 🔌 Router power supply: if the air conditioner and the router are connected to the same source (for example, via Powerline), interference may occur.

If your router is in the mode 802.11ac (5 GHz), temporarily disable this frequency or create a separate network for 2.4 GHz. In the router menu, this can be done in the section Wireless → Wi-Fi Settings. For models TP-Link Archer C6 the path will be like this: Advanced Settings → Wireless Mode → Frequency Splitting.

⚠️ Attention: Air conditioners Gree Networks with hidden SSIDs (hidden Wi-Fi names) are not supported. Before connecting, ensure the "Hide network" option is disabled in your router settings.

Method 1: Connecting via G+ app (official method)

The most reliable way is to use the proprietary app. G+ (previously Gree+). It is available for Android And iOS, but has a limitation: it only works with air conditioners manufactured after 2018. For older models (eg, Gree G10 2016–2017) an alternative method will be required (see Section 3).

Step-by-step instructions:

  1. Install the application:
  • Register an account:

    When you first launch it, you'll need to enter your email address and create a password. You can use your account Google or Apple ID for quick authorization.

  • Add a device:

    Click "+" in the upper right corner → "Add device" → "Air conditioner." Select the model from the list (if it's not there, select "Other").

  • Activate connection mode:

    On the air conditioner remote control, press and hold the button Wi-Fi (or Mode + Wi-Fi for older remotes) for 5 seconds until the indicator starts flashing green.

  • Connect your phone to the air conditioner's network:

    A network like this will appear in the Wi-Fi list on your phone. Gree-XXXX. Connect to it (no password required).

  • Return to the application:

    G+ will automatically detect your model and prompt you to select your home Wi-Fi network. Enter its password.

  • If at the stage of connection to Gree-XXXX an error occurs, try:

    • 🔄 Restart the air conditioner (unplug it from the outlet for 1 minute).
    • 📵 Disable VPN or proxy on your phone.
    • 🔌 Bring the phone closer to the air conditioner (maximum 1–2 meters).

    Install the G+ app|Register an account|Check that the air conditioner is on|Activate Wi-Fi mode on the remote control|Disable VPN on your phone-->

    Method 2: Manual Wi-Fi setup via remote control (for older models)

    Air conditioners Gree, released before 2018 (for example, series G10, G12 or U-Match), often don't support the G+ app. They require manual connection via the remote control. The instructions are for remotes with a button. Wi-Fi or Smart.

    Algorithm of actions:

    1. Turn on the air conditioner and make sure it is running in cooling/heating mode (not fan mode).
    2. Activate Wi-Fi setup mode:

      Press and hold Wi-Fi (or Mode + Wi-Fi) 5-7 seconds until the indicator starts flashing orange (connection standby mode).

    3. Connect to the air conditioner network:

      Find the network on your phone or PC Gree_Air_XXXX (default password is 12345678 or empty).

    4. Open your browser and go to the address 192.168.1.1The web-based setup interface will open.
    5. Select your Wi-Fi network from the list and enter the password. Save the settings.
    6. Wait for the reboot:

      The indicator on the remote control should change color from orange to green (successful connection) or red (error).

    If after saving the settings the indicator continues to flash orange for more than 2 minutes, check:

    • 🔌 The password you entered is correct (case sensitive!).
    • 📡 Wi-Fi channel compatibility (try setting channel 6 manually in the router).
    • 🔄 Availability of firmware updates for the air conditioner (see. Section 5).
    ⚠️ Attention: In manual mode some models Gree (For example, Lomo Inverter) require entering the router's MAC address. It can be found on the router's sticker or in the web interface at Status → Local Network.
    What should I do if the web interface doesn't open?

    If 192.168.1.1 opens the router's page, not the air conditioner's, there's an IP address conflict. Try this:

    1. Turn off Wi-Fi on all devices except your phone/PC.

    2. Connect to the Gree_Air_XXXX network and manually set IP 192.168.1.100 (mask 255.255.255.0).

    3. Repeat access to 192.168.1.1.

    Method 3: Configuring the router for a stable connection

    If the air conditioner Gree If my Wi-Fi connection keeps dropping, the problem may be with my router settings. Optimal settings for stable operation:

    Parameter Recommended value Where to change
    Wireless network mode 802.11n (or 802.11b/g/n) Wi-Fi Settings → Network Mode
    Channel width 20 MHz Wi-Fi Settings → Channel and Width
    MTU 1400 Local Area Network → MTU
    DHCP Enabled (IP range outside 192.168.1.100-192.168.1.200) Local Area Network → DHCP
    MAC address filtering Disabled Wireless Mode → MAC Filter

    For routers Keenetic It is additionally recommended to disable the "Load Balancing" function (Network Management → Balancing), as it can block traffic from IoT devices. ASUS RT-AX58U It is useful to enable this option Enable IGMP Snooping (Local Network → Route) for the correct operation of multicast packets that air conditioners use Gree for synchronization.

    If the air conditioner still turns off after the changes, check the router logs for errors like DHCP lease failed or Authentication timeout. IN TP-Link logs are available on the path System Tools → System Log.

    Method 4: Alternative connection methods

    If the standard methods don't work, try one of these options:

    4.1. Connection via Tuya Smart (for OEM models)

    Some air conditioners Gree, released for other brands (eg, Electrolux, Toshiba), use the platform TuyaIn this case:

    1. Install the application Tuya Smart.
    2. Add the device manually by selecting the "Air Conditioner" category.
    3. Follow the app instructions (similar to the G+ method).

    4.2. Use BroadLink or IR blaster

    If the Wi-Fi module in the air conditioner is faulty, but the remote control works, you can connect the device via an IR transmitter (for example, BroadLink RM4 Pro):

    • 📱 Set up BroadLink through his app.
    • 🔄 Add your air conditioner as an IR device by selecting the model Gree from the database.
    • 🌐 Connect BroadLink to your Wi-Fi network and control your air conditioner via the cloud.

    4.3. Connection via Home Assistant (for advanced users)

    If you use a smart home system Home Assistant, integration with Gree possible via component gree:

    climate:
    

    - platform: gree

    devices:

    - host: 192.168.1.100 # Air conditioner IP

    mac: 'AA:BB:CC:DD:EE:FF' # MAC address

    target_temp: 24

    To do this, first assign a static IP to the air conditioner in the router.

    Method 5: Solving connection errors

    Let's look at the most common errors and their causes:

    Error code Cause Solution
    E1 Incorrect Wi-Fi password or network not found. Check the password case. Make sure your network is broadcasting at 2.4 GHz.
    E2 Weak signal or interference from other devices. Move the router closer or reduce the transmission power of neighboring networks.
    WIFI-FAIL Unable to obtain IP address (DHCP problem). Reboot your router. Assign a static IP manually.
    Flashing red Wi-Fi module or firmware hardware error. Reset the air conditioner settings (button Reset on the remote control).
    E4 The air conditioner is already linked to another account. Reset the binding via Settings → Remove device on G+.

    If there is an error E1 or E2 appears at the password entry stage, try:

    • 🔄 Change your Wi-Fi password to a simpler one (e.g. 12345678) and repeat the connection.
    • 📡 Temporarily disconnect all other devices from the network to avoid overloading the router.
    • 🔌 Connect the air conditioner to another router (for example, from a phone in access point mode).

    Important: If after resetting the settings (button Reset (on the remote control) the air conditioner displays an error E4, this means the device is still linked to your cloud account. In this case, please contact Gree support with the serial number (found on the sticker on the indoor unit).

    Updating the Wi-Fi module firmware

    If your air conditioner is older than 2019, the issue may be due to outdated firmware. Updates are only available through a service center, but some models (e.g., Gree U-Crown) support over-the-air updates (OTA). To do this:

    1. Make sure the air conditioner is connected to Wi-Fi (even if the connection is unstable).
    2. In the G+ app, go to Device → Settings → Software Update.
    3. If an update is available, confirm the installation. Do not turn off the air conditioner within 10–15 minutes.

    For models without OTA, the update is only possible via USB port on the control board. This requires disassembling the unit and specialized software (for example, Gree Service Tool). If you are not a specialist, it is better to contact a service center.

    ⚠️ Attention: An incorrect firmware update may result in loss of Wi-Fi module functionality. If the air conditioner stops responding to the remote control after updating, perform a hard reset: unplug the unit for 30 seconds, then hold down Mode + Wi-Fi 10 seconds.

    FAQ: Frequently asked questions about connecting Gree to Wi-Fi

    Is it possible to connect a Gree air conditioner to Wi-Fi without the G+ app?
