2025.10.0

‼️ Breaking Change

The Car Assistant project has been migrated to ESPHome!
This migration brings many improvements (stated below) but has a few breaking changes that need your attention before you can upgrade.

What You Need to Know:

• You will need to reflash your device manually over serial to upgrade
• You will need to delete all your old Car Assistant config from Home Assistant (including the MQTT sensors & device tracker)
• While an MQTT connection is still possible with the new firmware, using WireGuard & the native API is highly recommended instead
• The PlatformIO branch will stay in an archived state for anyone who's not yet ready to upgrade
• Installation instruction for the new firmware can be found in the README.md file

What was Changed

• Migrated to ESPHome
• Astronomically improved stability
• Release numbers now follow a <year>.<month>.<release> scheme instead of using the commit ID
• The charging status sensor has been updated to display USB/GPIO Charging instead of USB Charging when using USB or GPIO to power the device
• The CPU frequency is no longer variable and will stay locked at 240MHz (ESPHome does not support changing the frequency during runtime)
• Fixed carrier names being reported twice
• Fixed CPU temperature & RAM usage data stopping being reported when WiFi is off
• Fixed GPS speed being calculated incorrectly

What was Added

• WireGuard support
• Home Assistant Native API support (requires WireGuard)
• More detailed device debug sensors
• PSRAM has been enabled & set to 120MHz
• OTA updates are now possible remotely (local upgrades via an AP will be restored in a future release)
• Cellular IP sensor (reports the modem's IP on the carrier's NAT)
• GNSS satellites currently visible by the modem sensor
• GNSS course sensor
• GNSS Horizontal Dilution Of Precision sensor
• Network type (2G/3G/4G) sensor
• Cellular signal strength type (Low/Medium/High) sensor
• Modem Bit Error Rate sensor
• GNSS Toggle
• Support for a LD2410S mmWave radar (uses the same connector as the PIR sensor)

What was Removed

• Power saving mode (due to ESPHome not supporting CPU frequency updates during uptime)
• Cellular fallback for GNSS (never worked on this modem)
• The device tracker MQTT config has been replaced with a Blueprint automation (See README.md for more info)
• Replaced the settings web page with the ESPHome web server (Configuration is now done in YAML)
• FTP support for SDCard files (Only accessible through the web server now http://<esp-ip>/file)
