Real-time sensor data visualization
Device control commands over BLE characteristic writes

What I Built

BLE scan and connection flow for discovering and pairing with the heat exchange device.
Real-time data display for temperature/sensor readings streamed from the device.
Control interface for sending commands back to the hardware.
Public showcase repo (`heat-monitor-showcase`) explaining the architecture for portfolio purposes.
