DashboardKeep local diagnostics for an early LEAF or Lancer
Ha-Kake turns an ELM327 diagnostic adapter and a computer into a local vehicle dashboard. Its early LEAF profile shows cell voltages, reported battery capacity and temperature; the Lancer profile supplies a smaller set of engine and diagnostic readings. It keeps history in SQLite and lets you arrange the display.
The documented profiles cover 2011–2012 LEAF ZE0 and 2009 Lancer ES, with checks on one 2012 LEAF and one 2009 Lancer. The documented installation uses macOS with Python 3.12. The dependency list includes macOS-only PyObjC packages, so a complete Linux installation route is not established. Some decodes are tentative, and polling can keep modules awake. Later LEAF years, native CAN and remote Pi/MQTT operation are not established by those car tests.
