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.

1. 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.
   
2. A suitable "Community" Binary File to flash onto the esp32 device: Latest Community Binaries
   
3. A Browser for flashing the binary: Use Google Chrome or Microsoft Edge (supports Web Serial) ESPHome.
4. USB Cable: A reliable cable for data transfer.

Steps

1. Download the appropriate Binary File

1. There a are a few community binary authors, but generally you should use the latest release from any of:
   1. Latest Community Binaries
   2. Bear Bin
2. 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

3. Connect to the ESP32-S3

1. On the ESPHome Web page, click the Connect button.
   

   

   
   
2. 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.

5. Flash the Firmware

1. ESPHome Web will erase the existing firmware and flash the SkiBean.bin binary.
   

   

   
   
2. The flashing process may take a few minutes. Wait for it to complete.
3. 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

1. Start your HiBean app, and click (+) in the upper right to add a new roaster.
2. Scroll down and select Skywalker
3. 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.
4. Happy Roasting!
