Created August 17, 2022 20:34

Proof of concept to get day-ahead electricity prices on the SHA2017 badge (old firmware)

	# Quick POC, for the SHA2017 badge on the last firmware before the ESP32-platform
	# Test through serial monitor, 115200 baud
	# 1. Press some buttons on the badge to wake it up
	# 2. Spam ctrl+C in the terminal until you get an empty prompt
	# 3. Type `import shell` to get a blank display and clean shell
	# 4. Press ctrl+E to enter paste mode
	# 5. Paste the first 14 lines of the below code, press ctrl+D to exit paste mode and execute
	# 6. Repeat above two steps for lines 15-27 and 29-41
	# Note: paste mode doesn't work well for large paste buffers, use mpfshell or similar to push whole files to the badge
