Error: Unable to import component

[khkl]

Hello together,

thanks for the petkit integration for homeassistant. unfortunately i get the following error after i install the package in the custom components folder and add petkit to the configuration:

Setup failed for petkit: Unable to import component: cannot import name 'CoordinatorEntity' from 'homeassistant.helpers.update_coordinator' (/srv/homeassistant/lib/python3.7/site-packages/homeassistant/helpers/update_coordinator.py)"

What am I doing wrong?

Thank you
Kai
