I posted this on the Micropython forum as well, but I have some code that is running on a Raspberry Pi Pico which runs an AHT20 temperature and humidity sensor, a seesaw soil sensor, and some LEDs. The code sends a request to an API which records the sensor data and tells it to turn on the lights (or turn them off). It all runs as expected, except... it doesn't start on device reset/restart. If I do soft reboot it does run. I've moved the network connection into the boot.py and then the rest runs (mainly) in main.py.
main.pyboot.py
main.py
