  2. Connect the soil moisture sensor to the GrowCube and insert the other end into the soil. There are four sensor interfaces(Marked A to D) on the GrowCube, and you can connect a sensor to any one of them. For example, when using port a to water plants, connect the sensor to port A of the GrowCube(Pay attention to the buckle position of the sensor connector and device interface). Then insert the soil moisture sensor vertically into the soil, the insertion depth should be more than ⅔ of the sensor, and the sensor insertion position should be as close as possible to the rhizome of the plant.

Network Configuration

The GrowCube has two working modes, Networking Mode and Direct Connection Mode. We recommend users to use the networking mode, which is connected to the router wifi at home or the wifi in the office environment, the device and the mobile phone can establish a local area network connection. Multiple devices can be added this way. Of course, if you are in an environment without WiFi, you can also use direct connection mode. The device itself will open access point, allowing the phone to connect directly. In direct connection mode, only one device can be controlled at the same time and only locally stored plants can be added instead of using the cloud database.

Networking Mode

Before configuring the network for the GrowCube, let's take a look at how GrowCube Networking Mode works:
The GrowCube is connected through the home / office WiFi network, it is the intermediary between mobile phone and GrowCube information transmission.
Here are the steps for GrowCube to configure the network:

    1. Open the app and enter the Mode Selection page, select "Networking Mode" and enter the Set GrowCube Network 'page, enter the home/office WiFi name and home/office WiFi password to be used, click "Continue", and there will be a pop-up "XXXX (your WiFi name) has been Saved";

Note: There is a drop-down selection menu at the WiFi name, users can choose WiFi by themselves, the recently used WiFi will be displayed first, do not use 5G network as it is currently not supported.


    1. Go to Connect The Device page, make sure that the red and blue indicators on the front of the GrowCube are flashing alternately before you initiate the connection, if not, the device is not ready to be connected. Please press the side button for 3s until you hear the "beep" sound. At this time, you can search for the WiFi named GrowCube xxxx launched by the device itself, where xxxx is a random combination of numbers and letters. Use your phone to connect the WiFi as prompted, check "The above operations have been confirmed" , and then click "Next". If the phone is already connected to the WiFi, the Networking page can be normally entered, and the App will send the WiFi name and password just saved to GrowCube, then GrowCube will connect by itself.


    1. After enter the Networking page, turn on the phone WiFi and disconnect the WiFi connection between the phone and GrowCube. And then connect the previously saved home/office WiFi to ensure that the phone and the device are connected to the same wireless network. In this page, the App will continuously check:

① Whether the device has been connected to the home/office WiFi ,
② Whether the phone has also been connected to the corresponding home/office WiFi ,
③ Whether the device and the phone have established connections through the home/office WiFi .
If the first step fails, the interface will pop up as follows, and you can choose to re-enter or reconnect. Re-entering will return to the WiFi Configuration page and re-enter the WiFi name and password. If you choose to reconnect, it will try to connect again using the current saved WiFi name and password.
If the second step fails, the interface will pop up as follows, you need to disconnect the WiFi connection between the mobile phone and GrowCube and then connect to the current home/office WiFi.
If the third step fails, the interface will pop up as follows, you can choose to reset or reconnect. Resetting will re-enter the Mode Selection page. Reconnecting is to return to the page and perform three rounds of connection attempts and detection again. If the above three steps are completed, the configuration is successful.

    1. After the network configuration successfully saved, enter the Configured Successfully page and generate the device name. The name can be renamed according to your preferences. At this time, the blue indicator on the front of GrowCube is solid.
