ESP32-DevKitC Boot Loop because of a stack overflow

[spoonwzd]

Similar to this issue my ESP32 seems to be stuck in a boot loop after flashing, but it's not the same error.

I've not connected to the BMS and have only changed the board to nodemcu-32s in esp32-example.yaml.

Try commenting out some of the sensors. I think it overloads the stack with all of the sensors in the example.

Another solution is to increase the stack size:

esphome:

Increasing the stack size as above sorted the issue - thanks!!
