Hi Elizabeth,
Not sure if this has been resolved, but I have been having the same issue. I replaced 29 with temp_f = "{:.2f}".format(temp_c * 9.0 / 5.0 +32.0)
. I noticed that when I ran the python code, after I made the changes to line 29, it would come back initially with the error that others pointed out. I ran it a few more times and then refreshed my dashboard on initial state and then ran the code again and it started to work. I would have to repeat this every time I stopped it and wanted to start it back up again. Not sure why it is doing it but as long as I can SSH into the pi and willing to run the code a few times it seems to work fine now.
Hi,
Great project but I am slightly stuck. My first issue is pip3 install pureio, for some reason I am getting a 404 error, so I am not sure if this is causing my issue, I don't think that it is but I could be wrong. My second issue is this I am using BME280 but not adafruit one, I have followed both options but still cannot get it to work. I am sure that this is caused by my sensor not being adafruit but this one or the crawlspace one still give me an error.
Still getting pretty much the same thing for some reason:
pi@enviro1:/etc $ python3 tempsensor.py
RuntimeError, trying again...
Traceback (most recent call last):
File "tempsensor.py", line 28, in
temp_f = temp_c * 9.0 / 5.0 + 32
TypeError: unsupported operand type(s) for *: 'NoneType' and 'float'
Again, if I try to run it a couple more times, it does eventually work. Just not sure why it runs successfully sometimes and not others.
Thanks.
