Not loading if motion sensor is off

[sti0]

If I switch the motion sensor off in the HUE APP the component is not loading at home assistant startup.

Error Log:
2017-12-12 23:00:58 ERROR (MainThread) [homeassistant.components.sensor] Error on device update!

If I turn it back on, the component is loading at home assistant startup.

I think you should consider the "on" state at the config parameter:
....
"config": {
"on": true,
"battery": 100,
"reachable": true,
"alert": "none",
"ledindication": false,
"usertest": false,
"pending": []
},
....

Maybe "reachable" as well.

Thanks for the suggestion, will incorporate into the next version.

If I turn off a motion sensor from the hue app or with a command I still get "Error updating Hue sensors" in home assistant log. Moreover the sensor attribute "on" stays on true even when the sensor is turned off. Maybe the component does not read the "on" attribute in config correctly?

@rafuz I've not tested the component under all possible conditions, PR to fix issues are welcomed :)
