Introducing Ring Signals for Mastra Agents

Mastra agents can now receive Ring doorbell events as notification signals with configurable priorities, letting the agent fetch a snapshot or video clip from the Ring API and decide what to do. Setup requires a Ring developer app, the @mastra/ring-signals package (0.1.0) and @mastra/core 1.81.0 or later, and RingSignals can target an existing channel thread such as iMessage or be followed via the client SDK's subscribeToThread().
