core: Insteon component error with 2242 Insteon Hub

Home Assistant release with the issue:

Last working Home Assistant release (if known):

Operating environment (Hass.io/Docker/Windows/etc.):

Hass.io on Raspberry Pi 3

Component/platform:

https://www.home-assistant.io/components/insteon Insteon Component

Description of problem: Have had the issue since switching from deprecated insteon_plm component to this one. Using an Insteon 2242 Hub. I downloaded the python code from the github repository: https://github.com/phareous/insteonlocal and was able to connect to the hub, and control my light and switch from the sample script there.

In the log in hass.io, I get the error ‘Error while setting up platform insteon’. Details of the error are:
