What Is Tera Term?

Tera Term is a terminal emulator that allows your PC to connect to devices via serial communication, making it easy to check logs and send commands.

With Tera Term, you can directly access key information from the GrowSpace Gateway, such as:

• MQTT broker connection status

• Network settings and error logs

• Device configuration values

• Real-time debug messages

It's a simple and powerful tool for both developers and system operators, allowing quick status checks without the need for a full development environment.
