Quick Video Overview
Step 1: Installing the Arduino IDE
If you haven’t already installed the Arduino IDE, follow these steps:
Download the Arduino IDE from the official Arduino website.
Install the software on your computer, following the on-screen instructions for your operating system (Windows/macOS/Linux).
Once installed, open the Arduino IDE.
Step 2: Installing the MAX6675 Library
To interface with the HW-550 (MAX6675) thermocouple, you will need the MAX6675 library.
Open the Arduino IDE.
Click on Sketch > Include Library > Manage Libraries.
In the Library Manager window, type MAX6675 in the search box.
Look for the library titled MAX6675 by Adafruit and click Install.
Wait until the installation is complete.
Step 3: Wiring the HW-550 (MAX6675) to Arduino Nano
Hardware Setup
Thermocouple (MAX6675) Connections: The code sets these pins:
pinSCK = 7
pinCS = 6
pinSO = 5
Wire your MAX6675 module as follows:
Arduino 
5V to MAX6675 
VCC
Arduino 
GND to MAX6675 
GND
Arduino 
7 (SCK) to MAX6675 
SCK
Arduino 
6 (CS) to MAX6675 
CS
Arduino 
5 (SO) to MAX6675 
SO
Note: If your MAX6675 module specifies different power requirements or has a regulator onboard, ensure you follow its recommended wiring.
Roaster Control Lines:
txPin = 3 (Arduino output)
rxPin = 2 (Arduino input)
Connect these pins to your roaster's control interface as required. These pins are used for sending and receiving signals from the roaster.
Power and Grounding: Ensure all grounds (Arduino, MAX6675, roaster interface) share a common ground. Double-check all connections to avoid damage to the board or sensors.
Preparing the Code
Open Arduino IDE: Launch the Arduino IDE on your computer.
Create or Open the Sketch:
Create a new sketch (File > New).
Copy and paste the provided code into the new sketch window.
Select Your Board and Port:
Go to Tools > Board and choose your Arduino board model (e.g., Arduino Uno).
Go to Tools > Port and select the port that your Arduino is connected to.
Verify Libraries:
Ensure the 
MAX6675 library is installed via the Library Manager as noted above.
SPI is included by default, no additional steps needed
Compiling and Uploading
Verify (Compile) the Code:
Click the Checkmark (Verify) button in the Arduino IDE toolbar to compile the code.
If there are errors, make sure you’ve selected the correct board, port, and have the MAX6675 library properly installed.
Upload the Code:
Once verification is successful, click the Right Arrow (Upload) button to upload the code to your Arduino.
After upload completes, the Arduino will reset and begin running the program automatically.
Running and Interacting
Serial Monitor:
Open the Serial Monitor by going to Tools > Serial Monitor.
Set the baud rate to 
115200 to match the code’s setting.
Commands: You can send commands via the Serial Monitor. Examples:
READ — returns the temperature readings and current duty cycles.
OT1;XX — sets heater duty cycle to XX (0-100).
OT2;XX — sets fan duty cycle to XX (0-100).
DRUM;1 — turns the drum on (100%), 
DRUM;0 turns it off.
FILTER;XX, 
COOL;XX — sets filter fan or cooling levels.
CHAN — responds with channel setup.
UNITS;C or 
UNITS;F — changes temperature units between Celsius and Fahrenheit.
OFF — shuts down all outputs.
Data Output:
The Serial Monitor will display temperature data from the thermocouple and any status messages.
If no commands are received for an extended period, the code will shut everything down for safety
Troubleshooting
No Temperature Reading:
Double-check thermocouple wiring and confirm the MAX6675 module is functioning.
No Response to Commands:
Ensure you’ve set the correct baud rate and are typing commands properly in the Serial Monitor.
No Upload / Compilation Errors:
Confirm you have the correct board selected and libraries installed.

Thank you TOU! for providing code which can be seen on kaffee-netz.de forum.

Skywalker V1 HiBean Firmware Installation
Pre-Requisites
This is still in Beta and code is still being worked on. Please report any issues you have to our Community Discord.
A supported ESP32 device: Ensure you have a supported ESP32 device, such as the Waveshare ESP32-S3 and a USB cable.  The S3 is a compact, low-cost device which can plug directly into the v1 Skywalker using a USB-C <-> USB-A adapter or suitable A to C cable.
A suitable "Community" Binary File to flash onto the esp32 device: Latest Community Binaries
A Browser for flashing the binary: Use Google Chrome or Microsoft Edge (supports Web Serial) ESPHome.
USB Cable: A reliable cable for data transfer.
Steps
1. Download the appropriate Binary File
There a are a few community binary authors, but generally you should use the latest release from any of:
Latest Community Binaries
Bear Bin
Download the .bin file that's appropriate for your particular esp32, and save it to a location which you can easily find later.
2. Open ESPHome Web
Go to ESPHome Web in your Chrome or Edge browser.
Connect the ESP32 to your computer using a USB cable or adapter.
3. Connect to the ESP32-S3
On the ESPHome Web page, click the Connect button.
A pop-up will appear with available devices. Select the port for your ESP32-S3 and click Connect.  This will generally show as a "USB JTAG/serial debug unit" on a COM port on Windows, or on /cu/usbmodem port on MacOS.  If your device does not appear here, or appears and disappears repeatedly, see Troubleshooting below.
4. Install the Binary File
Once connected, click Install.
Choose File when prompted
In the file selection dialog, locate and select the firmware .bin file you downloaded earlier.
Click Install to start the flashing process.
5. Flash the Firmware
ESPHome Web will erase the existing firmware and flash the 
SkiBean.bin binary.
The flashing process may take a few minutes. Wait for it to complete.
After successful installation, a success message will appear.
6. Visual Test
If all goes well, you should see an LED on the ESP32 begin to flash alternately red/blue.  If so, that means your esp32 flashed successfully.
If not, momentarily unplug and replug the ESP32 from the USB port.  After a few seconds, the LED should start flashing.  If not, something is wrong.  Ask on Discord.
If so, you can now plug the ESP32 into the back of the Skywalker.
7. Connect from HiBean
Start your HiBean app, and click (+) in the upper right to add a new roaster.
Scroll down and select Skywalker
In there select the "Skywalker Comm" (for Community) - the HB is for the official HiBean Skywalker Controller which can be purchased if you don't wish to flash your own device.
Happy Roasting!
Troubleshooting
Device Not Recognized: Ensure your USB cable supports data transfer.
Flashing Errors
Hold BOOT and press RESET (recommended method):
Hold down the BOOT button.
While holding BOOT, press and release the RESET button.
Continue holding BOOT for a second, then release it.
Unplug and replug while holding the BOOT button:
Disconnect the ESP32-S3 from power (USB).
Press and hold the BOOT button.
While holding BOOT, plug the USB back in.
Once connected, release the BOOT button.
