Var Integration

When I try to include a ‘variables’ folder in my configuration using this entry:

var: !include_dir_merge_list variables

The result is that it fails with this in the log:

’ Logger: homeassistant.setup
Source: setup.py:162
First occurred: 9:42:39 AM (1 occurrences)
Last logged: 9:42:39 AM

Setup failed for custom integration var: Integration failed to initialize.’
