Dashboard Guide

The dashboard is available on ESP32 builds that include ESP32_DASHBOARD. It runs from the device itself and is intended for local management at http://192.168.4.1/ while connected to the device hotspot.

Core Runtime Controls

Hardware: switch the active runtime mode between Legacy, HW3, and HW4
Speed Profile: follow the stalk automatically or lock a manual profile; HW4 adds Max and Sloth
Features: only Enable Logging remains on the main card; the other vehicle overrides are no longer exposed there
Injection control: stop or resume CAN injection without reflashing, then reboot from the UI when needed

CAN Tools

CAN Sniffer: live frame view with filtering by ID or known frame name
Wire / DBC ID toggle: switch between on-wire 11-bit IDs and prefixed DBC-style IDs
CAN Recorder: capture up to 2000 frames and export them as CSV
CAN Controller: inspect per-mux RX/TX/error counters and controller error flags
Live Log: view firmware log output directly in the dashboard

Connectivity And Updates

WiFi Hotspot: change AP name and password, optionally hide the SSID, and keep the values across reboots and firmware updates
WiFi Internet: scan for networks, connect as STA, and optionally store a static IP/gateway/mask/DNS configuration
Firmware Update: check GitHub releases, switch between stable and beta channel, enable auto-update on boot, or upload a local .bin manually
CAN Pins: override TWAI TX/RX GPIO pins at runtime for supported boards; settings are stored in NVS
Settings Backup: export and restore AP, WiFi, CAN pin, and update settings as JSON

Plugins

Plugins card: install from URL, upload a .json, or paste JSON directly when offline
Plugin list: inspect rules, enable or disable plugins, remove them, and spot overlaps with built-in firmware handlers
Plugin Editor: create plugins without hand-writing JSON, preview the result live, load an installed plugin back into the editor, download the generated file, and add a quick rule from shorthand such as 0x7FF mux=2 byte[5] = 0x4C
Rule Test: wait for a matching live CAN frame, apply one editor rule to that frame, then send the result repeatedly with a chosen count and interval
Plugin-based overrides such as nag suppression and Summon unlock can live here instead of on the main Features card
Build-default behavior still applies for the compiled firmware features that are no longer exposed as dashboard toggles
Dashboard cards can be collapsed individually with Hide / Show to keep the page shorter on mobile

Persistence Notes

WiFi hotspot settings, WiFi internet settings, update flags, CAN pins, and several runtime defaults are stored in NVS
Installed plugins live on SPIFFS, start disabled after install, and restore their enabled or disabled state on boot
On AtomS3 Mini builds, the built-in button can toggle injection and that state is also persisted
