Error in isy994 component after upgrade to 5.0.10

Hey all,

I updated the ISY994 to 5.0.10, and HA functionality seemed to work just fine. However, after restarting HA later on, I now get the following error:

2017-05-11 16:48:27 ERROR (MainThread) [homeassistant.setup] Error during setup of component isy994

This is with 0.44.2 btw.

Thoughts?
