2025.10.4

What's Changed:

• Configured a normal ESPHome WiFi AP (will auto turn on when the modem fails to connect)
• PIR has been replaced with Radar by default and is the recommended way to detect presence in your car
• SDCard support has been disabled by default to conserve flash space
• Added Home Assistant BLE Proxy support (Useful if you want to track phone presence in the car or have BLE devices in the car that you want to pass to Home Assistant)

Full Changelog: 2025.10.3...2025.10.4

2025.10.3

‼️ 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)
