set_heater generates an error on RPi3

[gdombiak]

Hi,

I'm running the example on the RPi3 with

python Adafruit_SHT31_Example.py

and I get this output

Status = 8010
Data CRC Error = False
Command Error = False
Reset Detected = True
Tracking Temp = False
Tracking RH = False
Heater Active = False
Alert Pending = True
Temp = 24.650 deg C
Humidity = 33.63 %
Traceback (most recent call last):

I'm using this library for this board https://www.amazon.com/gp/product/B019MGIC3Y/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1. I think it's the same. This was my first time I solder a board.

Any ideas what is producing this error? Or how to troubleshoot it?

Thanks,
Gaston

Yes - it seems to be the same board.

You are able to read status, temperature and humidity - so it should be on the address you assumed. To do this you have to be able to send commands to your board. Why it is not able to activate the heater is not obvious to me - sorry. Please inform me if you already solved this problem - sounds interesting.
