Our push notification service has a scheduled maintenance window on October 17 from 1 to 5 a.m., Eastern Daylight Time (or from 10 p.m. to 2 a.m. on October 16-17, Pacific Daylight Time).
During this time, you may not receive push notifications or Hello, Home messages in the SmartThings mobile app.
This will not affect functionality of any other SmartThings services.
For SmartApps that depend on push notifications for high priority security alerts, we recommend that you update your settings to send them via SMS notifications instead. You can update these preferences in specific SmartApp settings pages in your mobile app.
We apologize for any inconvenience.
