also tried w/ python3 w/ same errors.

# python3 --version

any ideas?

So it looks like because I use f-strings to do string formatting that requires python 3.6 or higher. I can swap all of those over to str.Format to possibly work with older python versions but I don't have time right now to do so, so you upgrading to 3.6+ might be quicker.

excellent, that helped a bit. now showing something new:

seems when it hits circuit #9 is barfs on zero/none

Sounds like the library is working at least but getting bad data for that particular channel. If you were planning on using the library within something else then you should be good to go.

[ikishk]

yup. thank you. any shortcuts to output raw json instead of depending on python formatting? ie. might be nice to have a big json dump for some ajax :)

[magico13]

You can always make the calls against their APIs directly. You can get the token out of PyEmVue after logging in with it and then use that for those calls. Alternatively you can use the json library to take one of the response objects and just json.dumps() it. If you wanted to call their API I have some documentation on it here https://github.com/magico13/PyEmVue/blob/master/api_docs.md

perfect and outside the box, love it :)
