Spaceballs - The Switch!

Convert the Concord Aerospace's Ludicrous Speed Panel into a 5 switch Zigbee on/off switch. Only tested with Home Assistant. Switches 1-4 will be turned on when the potentiometer is rotated (you may need to input your own calibration values though), eg. plaid will have switched 1-4 in ON state. GO switch is switch number 5 and operates independently.

Requires ESP32-C6 and ESP-IDF 5.2. Tested with WeAct Studio ESP32-C6-MINI.

Connecting hardware

Connect POT 1 to 3.3 VCC, POT 2 to pin 5, POT 3 to GND. Connect GO button to GND and pin 20. Additional switch goes to pin 21 (and GND). Optional reset switch is at pin 17.

If you want to change the behavior so switches 1-4 are toggled independently, uncomment #define INDEPENDENT_SWITCHES.

Resetting device

Jumper 3V3 to pin 23 and reset the device.

Building and flashing

Plug in your ESP32C6 to your computer (press BOOT, hold it and press RESET, then release BOOT) and replace com4 with the COM port the device appears on your computer.

1. idf.py -p com4 erase-flash
2. idf.py menuconfig
3. idf.py -p com4 flash
4. Get the MAC address from console (the other port for ESP32-C6)
5. Create a manufacturing partition using Zigbee Manufacturing Partition Generator Utility.
6. Clone the zigbee sdk repo and remove the from future.moves.itertools import zip_longest from tools/esp_zb_mfg_tool.py.
7. Install dependencies in ESP-IDF shell: python3 -m pip install -r requirements.txt and python3 -m pip install cryptography esp-idf-nvs-partition-gen crcmod
8. Generate an installcode with Python: python3 -c "import os;import crcmod.predefined;installcode=os.urandom(12);crc=crcmod.predefined.mkCrcFun('crc-16');print(installcode.hex() + hex(crc(installcode))[2:]);"
9. Install dependencies for mgf tool: python -m pip install esp_idf_nvs_partition_gen future
10. Run: python3 esp_zb_mfg_tool.py -i 7f91fbafb9ec53ee8097b3bb8fce -m 404ccafffe5627c4 -c 0x8000 -mn Espressif -mc 0x1338 (change first parameter to random string from previous command, second is MAC without colons)
11. Flash the binary to the zb_fct partition (at 0xf5000): esptool.py -p com4 write_flash 0xf5000 404ccafffe5627c4.bin
