Hi!

Does anyone know when will be python code/library avaiable for Grove - AHT20 I2C Industrial Grade Temperature and Humidity Sensor ?
Is eventually anyone succeeded to use it with pyton?

Hi @vidist
The general grove.py library for Seeedstudio Grove Devices includes a module for the AHT20.
It worked quite well for me:

github.com

Seeed-Studio/grove.py/blob/master/grove/grove_temperature_humidity_aht20.py

#!/usr/bin/env python

# Library for Grove - I2C Industrial Grade Temperature & Humidity Sensor (AHT20)

Just be aware that if you use the sensor with a recent version of the reTerminal, the I2C address of the AHT20 (0x38) will collide with the address of the built-in I/O expander. You will need to create a new I2C bus and map it to an available GPIO. This Instructable by JJ Slabbert might help:
