Code

main.py

Python
Create new Zerynth project and add two files: main.py and helpers.py
Enter your Wi-Fi credentials and Ubidots TOKEN where indicated:
import streams
from wireless import wifi
from xinabox.sh01 import sh01

streams.serial()

# SH01 instance
SH01 = sh01.SH01(I2C0)

from espressif.esp32net import esp32wifi as wifi_driver
wifi_driver.auto_init()

from ubidots.iot import iot

# configure SH01
SH01.init()
