Case study

hydrao-dump: decoding Hydrao shower-head Bluetooth data

hydrao-dump investigates the Bluetooth exchanges between Hydrao shower heads and their phone app, with packet captures, a Wireshark dissector and an MQTT receiver for Home Assistant. The author identifies shower volume, color thresholds, firmware and hardware versions, and device IDs while leaving temperature and flow fields unresolved.
