Connected health devices increasingly support health monitoring outside clinical settings, making secure and accessible physiological data important for patients and caregivers. However, device-specific applications and interfaces complicate the integration of readings from different devices. The Matter standard provides standardized device commissioning and protected communication, but its cluster library does not represent the health attribute measurement. We present a preliminary demo study of a Matter-based IoMT testbed with a specific HealthVitals cluster. Implemented in the connectedhomeip SDK on a Raspberry~Pi~5, the cluster exposes simulated heart rate, blood oxygen saturation, and body temperature. We examine commissioning, attribute retrieval, communication under simulated packet loss, and operational traffic through a reference controller. The study demonstrates that this custom telemetry model can operate within the tested Matter configuration without modifying commissioning or secure-session mechanisms. The resulting testbed gives researchers and device developers a concrete platform for investigating health-oriented extensions. It also supports exploration of local telemetry integration that could help patients and caregivers access readings across connected devices.
