Component/platform: custom component

Description of problem: I wrote a custom component to control the openmotics hub: https://www.openmotics.com/ The source code can be found at: https://github.com/woutercoppens/home-assistant

When I copy my modules in the modules directory of Home Assistant, everything works fine. However when I put my modules in the custom_components directory, I get all kinds of errors (see traceback).

Each time Home Assistant is upgraded, I have to copy the modules back into the components directory.

Right now it is not possible to create custom components that consists of multiple modules. Expected:

Problem-relevant configuration.yaml entries and steps to reproduce:

Additional info: I even tried to replace 'from homeassistant.components.openmotics import ...' with 'from 'homeassistant.custom_components.openmotics import ...', but that doesn't work neither.

Instead of

from homeassistant.components.openmotics import (OM_LOGIN, OM_LIGHTS, OM_OUTPUT_STATUS)

use

from custom_components.openmotics import (OM_LOGIN, OM_LIGHTS, OM_OUTPUT_STATUS)
