HA Lexus Status

A Home Assistant custom component that reads battery status from a Lexus UX300e (or any other Toyota/Lexus EV on the EU platform) via Lexus Connected Services and exposes it as Home Assistant sensor entities.

• Cleaned up the remaining stale Tibber naming and documentation references
• Updated compatibility wording and validation checklist for Home Assistant Core 2026.9.1
• Standardized the remaining charge time sensor unit to Home Assistant's official minutes unit

Lexus Connected Services API  ──►  Home Assistant sensors
       (battery, range, charging)

The integration authenticates against Toyota / Lexus Connected Services and reads:

• Battery state of charge (%)
• Estimated electric range (km)
• Charging status
• Remaining charge time (min)
• Timestamp of the last successful data fetch

Data can be fetched automatically on a configurable interval or on demand via an automation or the Home Assistant service call lexus_status.refresh.

1. Open HACS → Integrations → ⋮ → Custom repositories.
2. Add https://github.com/WickedGhost/lexus_status with category Integration.
3. Search for HA Lexus Status and install it.
4. Restart Home Assistant.

1. Copy the custom_components/lexus_status folder into your HA config/custom_components/ directory.
2. Restart Home Assistant.

Go to Settings → Devices & Services → Add Integration and search for HA Lexus Status.

The setup wizard walks you through up to four steps:

The integration polls Lexus Connected Services every N minutes (configurable, default 30). Useful when you want the sensors to stay current without any extra automation work.

No automatic polling. The sensors only update when you explicitly call the lexus_status.refresh service. Use this when you want full control over when the car is woken up, for example only after you know the car has been driven or plugged in.

# Example automation: refresh whenever the car is plugged in
automation:
  trigger:
    - platform: state
      entity_id: sensor.lexus_ux300e_charging_status
      to: "charging"
  action:
    - service: lexus_status.refresh

Immediately fetches the latest status from Lexus Connected Services for all configured vehicles, regardless of the configured update mode.

The battery_level sensor also exposes vin and last_lexus_update as extra state attributes.

After setup you can change the update mode and polling interval via Settings → Devices & Services → HA Lexus Status → Configure.

Before treating this as a production-ready install, verify the following in Home Assistant Core 2026.9.1:

• HA Core is running at version 2026.9.1 or newer
• The custom component is installed in config/custom_components/lexus_status
• pytoyoda>=5.0.0 has been resolved by Home Assistant without startup errors
• The integration config flow opens and accepts your Lexus Connected Services credentials
• A vehicle is selected from the account and the config entry is created
• The entities are created under the expected device and update cycle
• Manual refresh works via lexus_status.refresh
• No missing_library, cannot_connect, or auth errors are logged during startup

• cannot_connect during setup – Check that your Lexus credentials work in the MyLexus mobile app and that your HA instance has internet access.
• missing_library – Make sure pytoyoda>=5.0.0 is listed in the integration manifest and that HA has installed it (check HA logs on startup).
• EU accounts only – pytoyoda only supports Toyota Connected Europe. North American / Asian Toyota/Lexus accounts are not supported.
• Battery level not updating – The Lexus Connected Services API only refreshes the car's data when the car is awake (ignition on, or actively charging). Values can be stale for parked vehicles. In Manual mode, call lexus_status.refresh after you know the car is awake.
