Not sure why the requirements test is failing 🤔

ok to merge when tests pass.

So if I run the gen_requirements script it looks like it is trying to install the previous requirements instead of the update requirements. Is there something I am doing wrong?

[lorddaren]

So as an FYI, my gen_all_requirements was failling because I had an actual version of home-assistant installed in my dev environment. Once I pip uninstalled homeassistant and then python setup.py develop everything generated like it was supposed too. Let see if it passes now.

Is this okay to be merged even though it is stuck on the coverage/coveralls check?

[balloob]

Yep, ok to merge! 🐬
