  If your BMS system displays a communication error for your Gree Gateway, preventing the display and control of some or all units, several factors could be at play. First, ensure that you are using twisted-pair communication cable. Replace it if it is not. Check for any breaks or short circuits in the communication cable and weld any broken circuits or repair any short-circuited parts. Also, make sure the twisted-pair cable is at least 15cm away from any power cords; if this isn't possible, use a shielding steel pipe. Verify that the communication interface is correctly connected according to the manual's instructions. Finally, the Modbus Gateway(Pro) might be broken and needs replacement.

  If the circuit, device, and engineering installation for your Gree Gateway are normal, but the software still shows a communication error, you might be using the wrong display or controller that doesn't match the actual unit. To solve this, check the controller and wired controller models of your current unit. If the models are incorrect, contact the after-sales service center.

  If the circuit and other device layers are normal, but a specific device layer on your Gree Gateway isn't displaying information, it might be due to the relay. Ensure that the relay is correctly installed. If a relay is already installed, verify that its wire connections are correct. Install the relay correctly.
