Starting on 26 October, we will begin releasing a change to our Event History.
Any Device that generates an event that does not comply with the Capability schema will no longer be stored in the event history. No official SmartApps will be affected by this change. We have evaluated the most popular community SmartApps and were unable to identify significant impacts.
Some custom Groovy SmartApps that reference a device’s historical event
data may no longer work as expected. This is limited to SmartApps referencing the historical events; subscriptions of real time events will remain unaffected.
If you have custom SmartApp that is affected, provide a link below and our Developer Relations team will help you identify alternative solutions.
