SIN-4-RS-20_LEX: tilt partially supported but not exposed in frontend

[Wilboc85]

Description

While testing an ADEO / Leroy Merlin SIN-4-RS-20_LEX, I noticed an inconsistency between the generated definition, the MQTT payload and the exposed entities.

Environment

• Zigbee2MQTT: 2.11.0
• zigbee-herdsman: 10.1.0
• zigbee-herdsman-converters: 26.61.1

Device:

• Manufacturer: Adeo
• Model: SIN-4-RS-20_LEX

Observations

The generated external definition contains:

extend: [
    m.windowCovering({controls: ["lift", "tilt"]}),
    m.commandsWindowCovering({endpointNames: ["1"]}),
]

However the frontend only exposes:

• state
• position

No tilt entity is exposed.

Commands tested

Accepted without error:

closuresWindowCovering.goToLiftPercentage
closuresWindowCovering.goToTiltPercentage

Attributes

windowCoveringType = 8
configStatus = 3
windowCoveringMode = 8

currentPositionLiftPercentage = 0
currentPositionTiltPercentage = 0

installedOpenLimitTiltDdegree = 0
installedClosedLimitTiltDdegree = 65535

currentPositionTiltPercentage exists and can be read.

MQTT

After sending a tilt command, the following payload is published:

{
  "position": 100,
  "state": "OPEN",
  "tilt": 100
}

However reading:

currentPositionTiltPercentage

still returns:

0

Question

Is this expected for the Lexman firmware?

Or is the SIN-4-RS-20_LEX converter missing the proper tilt expose, even though the device appears to support the Window Covering tilt cluster?

I can perform additional tests if needed.
