The Wyze Band contains a display and sensors that remain useful even when the vendor's software no longer provides the openness an owner wants. openwyzeband explores whether that hardware can be understood through careful Bluetooth evidence rather than guesswork.
The project takes the form of a Bluetooth Low Energy research toolkit that scans the band, enumerates GATT services, records reads, writes, and notifications, and supports controlled protocol experiments. Its purpose is to create an open, documented path to the device's display and live sensors without guessing at unsafe commands.
The question behind openwyzeband
Reverse engineering invites premature conclusions: a writable characteristic is not automatically safe, and one observed packet is not automatically a command. The project therefore treats logging and controlled experiments as the primary instruments. Device owners, hardware hackers, and open-device researchers may benefit. Unsafe commands could damage a device or violate consent if used on hardware someone does not own.
How openwyzeband took shape
The toolkit scans for the owned device, enumerates GATT services, records reads, writes, and notifications, and supports experiments that change one variable at a time. The eventual goal is typed control of the display and direct live access to sensor data. Josiah set the open-control goal, supplied the owned device, and directed an evidence-first agent workflow rather than blind protocol guessing.
What the evidence supports
The toolkit and protocol-research structure exist, but the band is currently having trouble pairing with Josiah's phone. That goal remains incomplete because the band is currently failing to pair reliably with Josiah's phone. Preserving the blocker is important: open control is a research direction, not a capability the current artifact has already delivered.
The project is paused at a pairing problem and does not yet offer full display control or reliable live sensor access. Progress now depends on restoring reliable pairing and a known-good baseline before controlled, device-owned tests can map display and sensor behavior.
