Mastra agents can now take Ring doorbell signals: a snapshot at the door, then the agent decides what to do

Mastra agents gain Ring signals, so doorbell events can enter the agent's thread as notification signals with a configurable priority. Agents were usually configured to respond to software events, such as messages from Slack, Discord, iMessage and other supported channel providers. Ring signals turn a doorbell into an event source agents can act on, and the agent can then fetch a snapshot or video clip from the Ring API.

When an event arrives, the agent receives a snapshot of the doorway and can use it to flag visits that may need urgent attention. By default, the agent receives a snapshot image of each event. Setting visibleToModel to true on tools.clip and using a model capable of receiving video input lets the agent watch the video clips as well.

Events can be configured with a priority and summary per event type, repeats can be merged into one notification, and attributes can be attached for the agent to see. Configuration includes events for the priority and summary of each Ring event, attributes for notification attributes, and coalesce set to true to merge repeats. Ring signals send events to their own thread by default, but can subscribe to an existing channel thread through the target property, for example sharing the same resourceId and threadId with iMessage.

The demonstrated scope is a Mastra agent receiving doorbell events through Ring signals, which requires a Ring developer app linked to a Ring account and setup following the Ring integration guide. Each event carries a snapshot by default; watching video requires visibleToModel set to true on tools.clip and a model that accepts video input.

The material gives no recognition accuracy, latency or false-alarm figures, and how well the agent judges snapshots and clips depends on the chosen model and the prompts developers configure.
