[bartnaaijkens]

Home Assistant release with the issue:
0.72.1

Last working Home Assistant release (if known): not known

Operating environment (Hass.io/Docker/Windows/etc.):
Hass.io supervisor 113 on RPI3

Component/platform:
Home Assistant Cloud with Google Assistant https://www.home-assistant.io/components/cloud/

Description of problem:
Asking Google Assistant "Which lights are switched on" gives an "Unknown error occured with 5 devices".

Switching the lights (Ikea Tradfri connected via Deconz/Zigbee) on and off via Google Assistant works perfect.

Looking at the log a ZeroDivisionError occurs in dividing by color_temperature_mired_to_kelvin. See the logs
