Logging

media

Logging is available in development builds. It helps with troubleshooting firmware issues and configuration errors.

A serial monitor is required. The examples below use Microsoft Visual Studio Code with the Microsoft Serial Monitor extension.

Set serial monitor to:

• baud rate 115200

• line ending CRLF

Microsoft Visual Studio Code

Logging settings

You can enable serial logging channels in system settings:

• Configuration - read/write config messages

• Sensors - sensor messages

• Actors - actuator messages

• Mash kettle - messages for kettle 1

• Brew kettle - messages for kettle 2

• NACHGUSS kettle - messages for kettle 3

• Fermenter - fermenter mode messages

• System - general system messages

• Mashing process - mash process events

• Nextion Display - display messages

Each channel supports off, error, info, verbose.

Off

No output for this channel.

Error

Only error messages.

[E][SENSOREN.cpp:1600] setSenErr(): Test sensor error: #0 Sensor_Sud error state: 1
[E][SENSOREN.cpp:76] Update(): Sen: Sensor_Sud error #1 could not read temperature data

Info

Error messages plus process information.

[I][KETTLES.cpp:2044] debConsole(): set new powerlast: 1071746ms
[I][KETTLES.cpp:1922] webhook(): webhook response:
[I][KETTLES.cpp:2044] debConsole(): webhook on: 5000ms (mDutyCycle 5000 * Power 100 / 100)

Verbose

Includes error + info and full diagnostic output, including SSE broadcasts.

[V][SYSTEM.cpp:847] SSEBroadcastJson(): kettle hlt: {"ison":false,"state":false,"power":0,"enabled":3,"setp":0,"temp":"32.4"}
[V][SYSTEM.cpp:919] SSEBroadcastJson(): kettle sud: {"ison":false,"state":false,"power":0,"enabled":3,"setp":0,"temp":"32.4"}
[V][SYSTEM.cpp:839] SSEBroadcastJson(): kettle mash: {"power":0,"stepnr":0,"tempvalue":"50.4","target":0,"step":6,"timer":3}

System verbose logging also prints curl-like web server request traces.

Log line format

Example:

[V][SYSTEM.cpp:839] SSEBroadcastJson(): kettle mash: {"power":0,"stepnr":0,"tempvalue":"50.4","target":0,"step":6,"timer":3}

Parts:

[V] output type (Verbose)

[SYSTEM.cpp:839] source file and line

SSEBroadcastJson(): calling function

Message payload:

kettle mash: {"power":0,"stepnr":0,"tempvalue":"50.4","target":0,"step":6,"timer":3}

Boot log example

05:42:16.904 > [I][SYSINFO] starting Brautomat32 V 1.60.x Release
05:42:22.467 > [I][SYSINFO] mount filesystem LittleFS: ok, free heap mem: 192924
05:42:28.384 > [I][SYSINFO] mDNS http://Brautomat.local IP address 192.168.100.112 time: 05:42:27 RSSI: -83

This shows firmware version, mDNS host, IP, and filesystem mount status.

Test sensor error

You can trigger a test sensor error via URL. Sensors use IDs starting at 0.

http://Brautomat.local/setSenErr?id=0

Open the same URL again to clear the error.

• sensor 1 -> id=0

• sensor 2 -> id=1

• sensor 3 -> id=2

This is useful for testing Behavior in case of sensor error.

Logging with Microsoft VSCode

You can run VSCode in portable mode.

Download ZIP: Microsoft VSCode

1. Extract ZIP into any folder.

2. Create a folder named data next to Code.exe.

3. Start Code.exe.

Microsoft Visual Studio Code

Install extension Serial Monitor by Microsoft.

Microsoft Visual Studio Code

Microsoft Visual Studio Code

Open output (Ctrl+Shift+U), select Serial Monitor, then choose COM port and 115200 baud. Start with Start Monitoring.
