If your chime stopped working after a recent firmware or app update and you know you have powerkit installed correctly and using a good transformer that meet the DB1 requirement
- try this to restore your chime -

To those who been using the free lifetime 3 hours cloud storage. - After reinstalling your DB1, you will need to go back to the Settings page then scroll down a bit and click on the [Cloud Storage] button. On the CloudPage, click on the Recording toggle to enable the cloud recording again. You should not need to subscribe again since you are already subscribed to it when you first installed the DB1.
