Can you try to install netdisco manually? A common issue in the past was that one of the dependencies of netdisco does not contain the pre-compiled binaries for Python 3.5.

in case someone else comes across this like i did, here was what i tried that lead to a fix:
like fabaff said, i tried to run “pip3 install pywemo” and it spit out a bunch of errors, one of them being:
“error: command ‘gcc’ failed with exit status 1”
afer i installed gcc using dnf, the HA install ran just fine, and pywemo along with netdisco were installed!

details:
fedora 26
python 3.6 venv
