Please report any issues you have to our [Community Discord](https://discord.gg/UXcX929AZy).** 1. A supported **ESP32** device: Ensure you have a supported ESP32 device, such as the [Waveshare ESP32-S3](https://www.amazon.com/Waveshare-Development-ESP32-S3FH4R2-Dual-Core-Processor/dp/B0CHYHGYRH/) 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](https://github.com/MagnmCI/SkiBeanCommunity/releases) 3. A Browser for flashing the binary: Use Google Chrome or Microsoft Edge (supports Web Serial) [ESPHome](https://web.esphome.io/). 4. **USB Cable**: A reliable cable for data transfer. --- ### **Steps** #### **1.

[Bear Bin](https://github.com/galangl/SkywalkerRoasterLab/blob/main/Skywalker%20v1/Zero/ESP32S3_Zero_Artisan_HiBean_Roaster_Control_v2.2.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** 1. Go to [ESPHome Web](https://web.esphome.io/) in your Chrome or Edge browser. 2. Connect the ESP32 to your computer using a USB cable or adapter. --- #### **3. Connect to the ESP32-S3** 1.

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](https://www.aliexpress.us/item/3256808748885175.html) which can be purchased if you don't wish to flash your own device. 4. Happy Roasting! --- ### **Troubleshooting** - **Device Not Recognized**: Ensure your USB cable supports data transfer. - **Flashing Errors** - **Hold BOOT and press RESET (recommended method):** 1. Hold down the **BOOT** button. 2. While holding BOOT, press and release the **RESET** button. 3.
