Update frient powermeter led 2

[tbowmo]

This should fix Koenkk/zigbee2mqtt#19042

[tbowmo]

@Koenkk I have tested the integration locally, and it works, at least I get energy etc. from the device

{
    "battery": 100,
    "battery_low": false,
    "energy": 118.28,
    "interface_mode": "electricity",
    "linkquality": 112,
    "power": 421,
    "power_2": 357,
    "pulse_configuration": 1000,
    "update": {
        "installed_version": 196866,
        "latest_version": 196866,
        "state": "idle"
    },
    "voltage": 3100,
    "current_summation": null,
    "update_available": null
}

@Koenkk one thought here, could it be an idea to convert this to Number, instead of doing as number?

like this instead

const divisor = Number(msg.endpoint.getClusterAttributeValue('seMetering', 'divisor') ?? 1000);

(and likewise for the multiplier of course)

[Koenkk]

This value is always a number (or undefined) so it should not be needed. Thinking about this again, I'm not sure about these default values, why did you add them? By default it just publishes the raw value in case there is not multiplier/divisor

[tbowmo]

I had problems, because they where undefined, and so factor became null. Then on line 756, it checks if factor is not null, before calculating anything. That lead up to it reporting null as energy consumption.

When I added those default values, it was reporting like it should.

[Koenkk]

The divisor/multiplier can be forced in the configure. I would propose to have the same logic as instantaneousDemand here, expose raw value when no factor is defined

[tbowmo]

hmm.. even though that I defined the metering entity like

  electricityMeter({cluster: 'metering', power: {divisor: 1000, multiplier: 1}, energy: {divisor: 1000, multiplier: 1}}),

I had trouble in the fromZigbee.metering function. This was the previous release though, so things might have changed now.

Anyways, I have changed the logic a bit, so it now returns the raw value.. I'll get around to test things in a couple of days.

Suggested change

	current_summation: (args?: Partial<NumericArgs>) =>
	currentSummation: (args?: Partial<NumericArgs>) =>

[Koenkk]

Suggested change

	pulse_configuration: (args?: Partial<NumericArgs>) =>
	pulseConfiguration: (args?: Partial<NumericArgs>) =>

[tbowmo]

@Koenkk I have now tested the implementation, and it works. Both changing pulse counts, and setting current summation property.
So it's a go for a merge from me now.

Thanks!
