WebSerial

WebSerial is the quickest way to watch the live device log in the browser.

What it is used for

• view live log output without a USB serial monitor
• inspect Wi-Fi, MQTT, update and inverter messages in the browser
• copy raw protocol and error lines for issue reports

How to open it

• Open Menu
• Click Web Serial

Important note

If you want to send inverter commands and also see the answer cleanly in the Web UI, use the Debug page command field.

When WebSerial is most useful

• checking protocol detection
• capturing ERROR Send lines
• checking update and Wi-Fi reconnection logs
• collecting debug material for unsupported devices
