AI assistant: ask about a fault, a sensor or wiring; a question can be dictated. Device firmware update from the app, without the web interface. Actuator tests, live graphs and a rebuilt "About device" screen.

Actuator tests • Run several actuators at the same time — each row works on its own. • The screen now follows the device's own test session, so what you see matches what is actually running. • Clear reasons when a test stops: another actuator is holding the same channel, the app lost contact with the device, or another operation took over. Dashboard • Text cards format readings the same way the sensor table does — a sensor that is disabled or not fitted shows "--" instead of a raw value. Device screen • "About device" is now reachable straight from the connection screen: firmware and hardware details, reboot and disconnect are available even while the ECU is not responding. • Reboot and disconnect moved here from the More menu, each behind a confirmation. Connection and reliability • More reliable Bluetooth: requests are queued, so two overlapping ones no longer fail as busy. • Switching to another device now clears the previous one's features and settings — no leftover rows from a box you are no longer connected to. • When the device firmware is older than the app, you get a plain "device update required" notice instead of a generic error. Also: clearer names for "Operating hours detail" and "Device firmware update".

• Sensors are now described by the connected device: the app takes the sensor list, labels, units and their order from the device's own schema, so a newer device shows its new readings without waiting for an app update. • Coolant temperature is reported as a real temperature instead of a raw sensor value, and a disconnected or shorted sensor is now shown as a fault rather than as an implausible reading. • Honest connection state: when the link to the device drops, the app says so and stops showing stale values, then recovers on its own when the device is back in range. • "Hours matrix" is now "Operating hours detail" — same data, clearer name. • Reboot and disconnect moved to More → About device, next to the rest of the device information. • Assorted fixes and interface polish.

— PIN protection is now set up in the app: enter a code, repeat it, and confirm the current one to turn it off — the Service tab shows a badge with the number of overdue intervals — graphs show minimum and maximum instead of the median, each toggled separately — the About device screen shows the 2TBox device bootloader type, and rows copy on tap — firmware for the connected device can be installed from the app — fixes: service intervals sometimes failed to load, sensor values jumped in length, settings stayed open after the device disconnected
