Add solar charge controller integration and firmware
App: - New DeviceRole.solar with its own BLE session/protocol/state (SolarSession, VanAlignSolarProtocol, SolarState), mirroring the leveling sensor but deliberately not wired into the Live Activity. - BluetoothManager now keeps an in-memory history per metric (voltage, current, power) instead of a single primary-metric series; cleared on app restart by design, not persisted to disk. - DeviceDetailView shows a channel picker above the history chart when a device has more than one chartable metric. - AddDeviceView recognizes the solar service UUID during setup. - DemoData gets a simulated solar device so the integration can be checked in the simulator without hardware. Firmware: - Add esp32_ble_solar.yaml (Votronic solar charge controller over BLE) and simulated variants (esp32_ble_sim.yaml, esp32_ble_solar_sim.yaml) for testing without a vehicle. - esp32_ble.yaml: set flash_size/psram for the ESP32-S3 N16R8 module.

# VanAlign Solar - Votronic Solarladeregler über BLE
|
||||
#
|
||||
# Zweiter ESP32 im Fahrzeug, unabhängig vom Neigungssensor (esp32_ble.yaml).
|
||||
# Liest den Votronic-Solarladeregler über den Displaylink-Port (UART) mit der
|
||||
# externen Komponente github://syssi/esphome-votronic aus und stellt die
|
||||
# Werte - genau wie beim Neigungssensor - über einen eigenen BLE-Service
|
||||
# bereit. Zusätzlich (für Debug-Zwecke) läuft WLAN mit und die Werte werden
|
||||
# auch auf dem eingebauten Webserver (Port 80) angezeigt - MQTT und die API
|
||||
# sind weiterhin nicht enthalten. WLAN-Zugangsdaten liegen in secrets.yaml
|
||||
# (lokal anzulegen, ist per .gitignore ausgeschlossen).
|
||||
#
|
||||
# Verkabelung: UART TX=GPIO4, RX=GPIO5 an den Displaylink-Port des Reglers,
|
||||
# Baudrate 1000 (kein Tippfehler - das Votronic-Protokoll nutzt diese
|
||||
# ungewöhnlich niedrige Rate). Board/Pins ggf. an die tatsächlich verbaute
|
||||
# Hardware anpassen, hier als ESP32-S3-DevKitC-1 wie beim Neigungssensor
|
||||
# angenommen.
