homeassistant.exceptions.HomeAssistantError: Entity id already exists error in 0.63

[arsaboo]

Home Assistant release (hass --version): 0.63

Python release (python3 --version): 3.6.2

Component/platform: NA

Description of problem: On restart, I am seeing this Entity id already exists error. I am guessing it is related to #11979

Traceback (if applicable):

Which platform? Seems like the platform is handing out duplicate unique ids
