I’ve got a Firebeatle 2 ESP32-C5 and while I struggled to get it working on ESPhome, it’s now behaving, and I’m able to wirelessly update it using esphome as well. My initial config looks like this:
esphome:
name: firebeetle-c5
friendly_name: FireBeetle C5
esp32:
variant: esp32c5
flash_size: 4MB
framework:
type: esp-idf
version: recommended
I followed the above instructions and flashed it with the ESP-Flasher the first time.
Good luck!
