As part of our continued efforts to improve the SmartThings platform we are rolling out the next step of the Cassandra migration. This change provides us much better insight and control over our data storage needs, improved stability, and a foundation that can scale SmartThings for the long term. We’re excited about these changes, and plan to roll out the next phase of the migration tomorrow, Tuesday, November 25th.
As part of this change, events older than a week old will no longer be accessible to SmartApps or to view in the mobile and web clients.
Here’s what you can expect:
- In the mobile app and web-based views, all event feeds will stop reporting when you get past seven days old.
- In the mobile app, the “Recently” feed will only contain events from the past seven days. In some cases this will mean the feed will be empty.
- SmartApps (both real and simulated in the IDE) will only be able to access events from the past 7 days. If a SmartApp queries for events, it will not find any more than seven days old. SmartApp state is not affected. The latest state for an attribute, for example,
latestState('motion'), is unaffected. Apps will always have access to the latest state of an attribute, regardless of how long ago it was.
Please let us know if you have any questions or feedback.
