Home Assistant Core 2025.8.0 → 2025.9.0

Encoding units containing the μ character

The encoding for some units that contain the μ character has been changed. Users that consume state data from sensors that have changed units will be impacted (such as exported state data to InfluxDB). The units with a changed encoding are:

• μSv/h for the aranet integration as a unit for radiation rate
• μS/cm for UnitOfConductivity.MICROSIEMENS_PER_CM
• μV for UnitOfElectricPotential.MICROVOLT
• μg/ft³ for concentration in micrograms per cubic foot
• μg/m³ for concentration in micrograms per cubic meter
• μmol/s⋅m² for the fyta integration as a unit for light
• μg for UnitOfMass.MICROGRAMS
• μs for UnitOfTime.MICROSECONDS

1-Wire

The raw_value attribute was previously deprecated and has now been removed.

Alexa Devices

The sound list has been updated to match the one used by the Alexa Mobile app. The variant parameter is no longer required.

Check your automations to ensure the selected sound is still present.

Husqvarna Automower BLE

The integration now requires the Automower PIN when being set up. This ensures Home Assistant can communicate with more models of mowers and with higher security levels.

KNX

KNX scene entities now also change their state when a scene was activated externally (from bus). Previously they only updated when activated from within Home Assistant.

SIA Alarm Systems

SIA alarm status code CF (armed with malfunctions) is now mapped to armed_away instead of to armed_custom_bypass.

SwitchBot Bluetooth

The battery property on vacuum entities is being removed in Home Assistant. Therefore, this property is now removed from this integration and is replaced by a battery level sensor.

Please review your automations, scripts, and dashboards using the battery property and update the code to use the battery sensor instead.

Yale August

The August integration now uses OAuth authentication with Yale August's official API. This is a required one-time breaking change as the unofficial authentication method will stop working soon. This migration helps reduce unnecessary load on Yale August's servers while ensuring continued access for all users.

When you update Home Assistant, you'll be prompted to re-authenticate your August account:

1. Select the notification or go to Settings → Devices & services → August
2. Select "Reconfigure" and follow the OAuth flow to sign in
3. Once authenticated, your devices will work exactly as before

We're grateful to Yale August for officially supporting Home Assistant with dedicated API access!
