[Device Support Request] Tuya Zigbee smart energy meter DDS238-2 Zigbee with a new manufacturer variant (_TZE200_bkkmqmyo)

Hi, I purchased this device which was markes as working with zha, unfortunatrly I got one with a new manufacturer, and, upon pairing, no entities appear. This is the signature

{
  "node_descriptor": "NodeDescriptor(logical_type=<LogicalType.Router: 1>, complex_descriptor_available=0, user_descriptor_available=0, reserved=0, aps_flags=0, frequency_band=<FrequencyBand.Freq2400MHz: 8>, mac_capability_flags=<MACCapabilityFlags.AllocateAddress|RxOnWhenIdle|MainsPowered|FullFunctionDevice: 142>, manufacturer_code=4098, maximum_buffer_size=82, maximum_incoming_transfer_size=82, server_mask=11264, maximum_outgoing_transfer_size=82, descriptor_capability_field=<DescriptorCapability.NONE: 0>, *allocate_address=True, *is_alternate_pan_coordinator=False, *is_coordinator=False, *is_end_device=False, *is_full_function_device=True, *is_mains_powered=True, *is_receiver_on_when_idle=True, *is_router=True, *is_security_capable=False)",
  "endpoints": {
    "1": {
      "profile_id": 260,
      "device_type": "0x0051",
      "in_clusters": [
        "0x0000",
        "0x0004",
        "0x0005",
        "0xef00"
      ],
      "out_clusters": [
        "0x000a",
        "0x0019"
      ]
    }
  },
  "manufacturer": "_TZE200_bkkmqmyo",
  "model": "TS0601",
  "class": "zigpy.device.Device"
}

Tried to adapt other quirks that were shared in the past with no success

# Reactive power units
...
POWER_KILO_VOLT_AMPERE_REACTIVE_HOUR: Final = "kvarh"

According to the specification the units would be kVAr:

I believe that the total_reactive_power attribute is a integer:

• https://github.com/zigpy/zigpy/blob/8a2c7548065367d7e94ddf5857652ca1cd087e70/zigpy/zcl/clusters/homeautomation.py#L190

So, the 23/100=0,23 --> 0

The problem is that total_reactive_power don’t configure any multiplier or divisor that can allow the decimal values.

Maybe you can keep the value as is in the _update_attribute and overwritte the formatter in the ElectricalMeasurementTotalReactivePower:

    def formatter(self, value: int) -> int | float:
        """Return 'normalized' value."""
        value = float(value) / 100
        if value < 100:  # only round tinny values
            return round(value, self._decimals)
        return round(value)
