It helps users achieve comprehensive real-time device status monitoring, parameter visualization, and system display. Through official strategies and automated control strategies, it improves energy efficiency, user comfort, and system stability, enabling refined energy management.
2. Login and Account Management
2.1 Account Information
On first use, users can obtain the device login credentials from the device nameplate (located at the bottom of the device):
- Login Username:
admin(default) - Initial password: Refer to the KEY field on the nameplate
- Device serial number (SN)
2.2 Web Login
Users can access the local web interface via a browser to log in to the system. Both wired connection and LAN connection methods are supported.
- 1️⃣ Wired Connection
- 2️⃣ LAN Connection
- Power on the device and connect the device WAN port to the PC WAN port using an Ethernet cable. Ensure both are on the same local network.
- Enter the following address in the browser: http://169.254.254.254 and press Enter.
- On the login page, select your country/region.
- Enter the username and password, then click Login to enter the system.
This method is used when the device has already been connected to the network via the mobile app.
Steps:
- Complete device addition and network configuration in the mobile app.
- Go to the device details page in the app to check the current device IP address.
- Ensure the PC and device are on the same local network (same router).
- Enter the device IP address in the browser (e.g., 192.168.xxx.xxx).
- Enter the username and password, then click Login.
This LAN access method requires the device to be successfully connected to the network. If access fails, please check the network status or use the wired connection method.
Please select the correct country/region carefully. It cannot be changed after the initial selection.
2.3 Change Password on First Login
For security reasons, users must change the initial password upon first login before continuing to use the system.
Description
After the first login, the system will automatically display a “Security Risk Warning” prompting the user to change the password. This is a mandatory step, and the system cannot be accessed until the password is updated.
Procedure
Users must enter the following information:
- Old Password: Enter the current initial login password
- New Password: Set a new password

After completion, click Confirm to update the password.
It is recommended that the password meets the following criteria:
- Includes uppercase letters, lowercase letters, numbers, and special characters
- Minimum length of 8 characters
- Avoid simple or commonly used passwords (e.g., 123456, admin)
- The password is an important credential for device management. Please keep it secure.
- If the password is forgotten, it cannot be recovered through the system. It can only be reset via the device RESET button.
- After performing RESET:
- The password will be restored to the default value;
- Device configurations will need to be reconfigured.
- It is recommended to securely record your password.
- Change the password regularly to improve security.
- Avoid sharing credentials among multiple users.
After successful password change, the system will return to the login page. Re-enter the updated username and password to continue device configuration and management.
2.4 Forgot Password
If users forget their login password, they can refer to the “Forgot Password?” option for reset instructions.
