[Device Support Request] - ZHA - Legrand / Bticino K4003C switch doesn't support status light

[m4r1k]

Problem description

The problem

The K4003C BTicino switch in ZHA doesn't support three key features:

• led_in_dark
• led_if_on
• identify

Those are fully supported by zigbee2mqtt https://www.zigbee2mqtt.io/devices/K4003C_L4003C_N4003C_NT4003C.html

Today I've confirmed that the status light of the switch cannot be configured with the ZHA integration

This issue was originally reported by @PoVPoV29 but nobody picked it up. https://github.com/home-assistant/core/issues/80720

This issue was also reported on HA GitHub https://github.com/home-assistant/core/issues/110009

It seems like zigpy defines the two required attributes here: https://github.com/zigpy/zha-device-handlers/blob/bfbfb4876d1811440b4a05cac9e3b83311d194a8/zhaquirks/legrand/init.py#L20-L21

However, I'm seeing ManufacturerSpecificCluster in Home Assistant instead of Legrand Cluster, so these attributes are not exposed in the UI.

I was able to manually enable this feature using the ZHA Toolkit: Write Attribute service with the following properties:

led_dark (show blue indicator when light is off)

• Target Endpoint: 1
• Target Cluster: 64513
• Attribute Id or Name: 1
• Attribute Value: Bool.true

led_on (show blue indicator when light is on)

• Target Endpoint: 1
• Target Cluster: 64513
• Attribute Id or Name: 2
• Attribute Value: Bool.true

---

As a side note, I'm not sure exactly what the value of dimmer is supposed to indicate. I read the value from two devices locally and they returned the following:

WNAL10W1: 0x00, 0x01 WNAL50W1: 0x01, 0x01

ZHA is still not able to fully handle Legrand / Bticino devices. This issue cannot be closed yet.

I think the dimmer option is for disabling the K4411C dimming option and force it to behave like a switch.

I think that the bticino device doesn't match the legrand querk at all.
