Hello @Peter-Sain most GPIOs on the ESP32 can be setup to do different things - so yes an no, GPIO32 and GPIO33 are not per se analog pins, but they can be if needed. However the DS18B20 is a OneWire component which is a digital bus (and not analog). I just ran a test (Arduino) with my M5StickPlus and either GPIO32 or GPIO33 can be used just fine to talk to a OnWire DS18B20 temperature sensor. Did you connect a 4.7 k resistor between VCC and OneWire data line? Could you share your code? Thanks Felix

@sconstan Hi, I was working on that. I have a version of CanAirIO Firmware working with Home Assistant. And now CanAirIO Firmware support M5StickCPlus M5AtomLite and M5CoreInk. Maybe I think is possible that works with M5 Core2 Home Assistant Support Home Assistant first release.

I've been using this on Core2 for a couple of months now and it is excellent. The main improvement is the LCD graphics library is Lovyan's GFX library, whereas the current M5 library is a quite old version of Badmer's TFT-eSPI.

In theory you need to manually test to get the base data before you can start auto testing to have data to compare the results against.

looks great

@Rop Great job with the i2c_manager component. I will test it ASAP since I had many troubles with Espressif's i2c driver.
