Clock and timer power saving

On every board, the clock and stopwatch/Locksport Timer pause background Wi-Fi and Bluetooth scanning. Lap history and time/date settings also stay paused. Return to the radar or other tools to resume scanning; a running timer keeps counting in the background. Previously configured Wi-Fi clock recovery may briefly connect for time synchronization. See power-saving behavior.

Personal themes and DZ_AZ

Build your own clock, radar and counter in the Custom theme tab. Add a logo, choose colors, hands and numerals, and enable locksport controls. The personal slot appears on the device only after you explicitly install a design. Creator guide.

DZ_AZ adds a crow-and-name emblem, rotating feather radar sweep, and short/long feather clock hands. Theme guide.

Supported hardware

The four full boards share the radar, 34 built-in themes, 32 built-in logo watch faces, timers, notebook, badge editor, radio tools, and BLE Lab. StopWatch and Waveshare AMOLED support 2 MiB captures and 2 MiB recon sessions. Their total file storage differs.

Lite provides five button-operated pages: radar, clock, timer, signals, and diagnostics. It shares detection and all 34 built-in themes, with compact clocks. It does not include Badge Studio, audio, or active labs.

Firmware is board-specific. The Waveshare 1.75C and non-C models have different wiring. Hardware guide · Feature comparison · Tested hardware and limitations

Tools

• Detection and Hunt: Wi-Fi/BLE signature matching, evidence labels, filtered signal strength, per-family alerts, watch/ignore rules, and local encounter history.
• Recon: surveys, protocol counters, packet captures, sessions, and CSV exports. Recon guide
• BLE Lab: GATT inspection, explicit pairing, profile storage, emulation, and a cached-read bridge. Capabilities and limits
• Clock and timers: analog/digital watches, stopwatch, locksport timing, and separate Time, Date, and Sync settings. USB sets local time and timezone. Devices without an external RTC need USB or configured Wi-Fi after complete power loss. Clock setup
• Badge Studio: prepare and upload your own artwork from the browser. Open Studio

Detection matches observable radio signatures; it does not establish intent, ownership, or recording state. Radar radius represents signal strength, and its angle is decorative. Silent devices, Bluetooth Classic, and 5/6 GHz Wi-Fi are outside coverage. Detection evidence
