Hi
I am having problems getting my Enviro to work with a Pi Zero WH which appears to otherwise work OK.
I have used a new up to date installation of Symbian and followed your instructions for installing the software for the Enviro but this throws up a number of errors.
Trying to run the Python demo program weather.py and other demos fail with the following message
pi@raspberrypi:~/enviroplus-python/examples ls
adc.py gas.py noise-amps-at-freqs.py
all-in-one-no-pm.py icons noise-profile.py
all-in-one.py lcd.py particulates.py
combined.py light.py weather-and-light.py
compensated-temperature.py luftdaten.py weather.py
pi@raspberrypi:~/enviroplus-python/examples python weather.py
Traceback (most recent call last):
File “weather.py”, line 4, in
from bme280 import BME280
File “/usr/local/lib/python2.7/dist-packages/pimoroni_bme280-0.0.2-py2.7.egg/bme280/init.py”, line 2, in
from i2cdevice import Device, Register, BitField, _int_to_bytes
ImportError: No module named i2cdevice
I would be grateful for any help.
The error messages generated during installation of the Enviro software follow
