2018-02-24 23:21:07 ERROR (MainThread) [homeassistant.config] Invalid config for [light.template]: [KitchenOh_Lights] is an invalid option for [light.template]. Check: light.template->lights->KitchenOh_Lights. (See ?, line ?). Please check the docs at https://home-assistant.io/components/light.template/
Your problem is almost certainly your indenting. Compare what you wrote to the docs.
Also, watch that Home Assistant will turn KitchenOh_Lights into kitchenoh_lights for creating the entity ID. It may be that it’s complaining about that too, and you should use lowercase.
