ValidationError: MotionSensor fails setup when batteryPercentage is missing

[JoeWanne475]

Hi,

I’m running Home Assistant with the custom integration dirigera_platform.
During setup the integration fails with a Pydantic ValidationError when at least
one motion sensor does not report attributes.batteryPercentage.

Stacktrace excerpt:

pydantic_core._pydantic_core.ValidationError: 1 validation error for MotionSensor
attributes.batteryPercentage
Field required [type=missing]

The IKEA Dirigera hub returns a valid motion sensor object, but without
batteryPercentage in attributes. This causes the entire config entry setup
to fail.

Observed behavior:

• Integration setup aborts completely
• No devices are created
• Happens consistently with a specific motion sensor

Expected behavior:

• batteryPercentage should be optional
• Integration should tolerate missing battery values and continue setup

Additional notes:

• The affected device is visible in the IKEA Smart Home app
• Firmware is up to date

I believe should define batteryPercentage as optional
(e.g. int | None = None) to avoid hard failures on incomplete device payloads.

Thanks!

This is fixed in the nrbrt/dirigera_platform fork (v0.2.1). The batteryPercentage attribute is made optional so sensors without it don't fail setup.
