You can monitor your Google Home Graph API quotas to prevent service
disruptions and verify the reliability of your integration. Ignoring quota
usage can result in failure to call for API functions like ReportState and
impact users' experiences.
If you reach your quota limit, you can increase it by reaching out to ha-certification@google.com. See HomeGraph API limits for more information.
