IKEA STARKVIND air purifier (E2007) fan percentage unavailable in auto mode breaks Powercalc

What happened?

When using the IKEA STARKVIND air purifier (model E2007) in auto mode, the virtual power sensor created by Powercalc reports an "unknown / unavailable" state. This occurs because Home Assistant derives the fan entity's percentage attribute from fan_mode. In auto mode, however, this value is set to auto, causing the percentage value to drop even though the actual fan speed remains available via fan_speed (0-9).

What did you expect to happen?

The Powercalc sensor should continue to calculate and display valid power values based on the current fan speed (fan_speed) even when the air purifier is in auto mode, rather than becoming unavailable.

How to reproduce it (minimal and precise)

1: Pair the IKEA STARKVIND air purifier (E2007) with Home Assistant via Zigbee2MQTT.

2: Create a Powercalc sensor for the corresponding fan entity.

3: Switch the air purifier to auto mode (auto).

4: Observe that the percentage attribute becomes missing, causing the Powercalc sensor to go unavailable.

No response

Start by locating the IKEA STARKVIND E2007 device definition and inspect how auto mode exposes fan_mode, fan_speed, and the fan percentage value. Reproduce the device state through Zigbee2MQTT, then verify that auto mode preserves the available fan speed so the Powercalc sensor no longer becomes unavailable.
