[Device Support Request] Issue with switch_acn047 (Aqara T2 Dual Relay): Voltage Reports 0 and Temperature Is None in ZHA

[luistelmocosta]

Problem description

General Information

• Device: Aqara T2 Dual Relay (Model: lumi.switch.acn047)
• Integration: Zigbee ZHA
• Home Assistant Version: 2024.12.2
• Zigbee Coordinator: Sonoff Zigbee USB Dongle Plus

Problem Description

I am experiencing unexpected behavior with the Aqara T2 Dual Relay after integrating it into Zigbee ZHA.

1. Voltage Reporting Issue:

• The ElectricalMeasurement cluster always reports the voltage as 0, which seems incorrect given the device's functionality.

2. Device Temperature Reporting Issue:

• The DeviceTemperature cluster's Value attribute consistently returns None when queried.
• This behavior is unexpected since the cluster is present, and I would assume the relay should provide internal temperature readings.

Based on the zhaquirks quirk for this device (lumi.switch.acn047), these clusters are expected to function:

replacement = {
    ENDPOINTS: {
        1: {
            PROFILE_ID: zha.PROFILE_ID,
            DEVICE_TYPE: zha.DeviceType.ON_OFF_SWITCH,
            INPUT_CLUSTERS: [
                BasicCluster,
                Identify.cluster_id,
                Scenes.cluster_id,
                Groups.cluster_id,
                OnOff.cluster_id,
                MultistateInputCluster,
                DeviceTemperature.cluster_id,
                MeteringCluster,
                ElectricalMeasurementCluster,
                OppleCluster,
            ],
            OUTPUT_CLUSTERS: [Time.cluster_id, Ota.cluster_id],
        },
        ...
    },
}

• The DeviceTemperature and ElectricalMeasurement clusters are included in the quirk's replacement, so I assume these should be operational.

Thank you!

Solution description

If these clusters are intended to function, I request:

• Verification of the ElectricalMeasurement cluster's voltage reporting.
• Clarification or a fix for the DeviceTemperature cluster returning None.

If these are unsupported by the device, adjusting the quirk to reflect the actual capabilities would enhance usability.
