MeterCC.ts creates value labels that cannot be distinguished

Describe the bug

When selecting a meter value in zwavejs2mqtt (e.g. from a Shenzehen Neo NAS-WR01ZE Wall Plug) the selection box shows identical labels for all meter values which cannot be distinguished for which unit it is (kWh, W, V, A).

This is a screenshot from the value selection:

This is a screenshot that shows that multiple values have identical labels and would not be able to distinguish, if the UI would not output the unit as well:

Maybe the value labels could be improved a bit as well (shorter with more meaningful names).

Device information

Which device(s) is/are affected (make/model)? Shenzehen Neo NAS-WR01ZE Wall Plug What are the node IDs? Node 080 (see logs). Device IDs: 600-4135-512 (0x0258-0x1027-0x0200)

The bug affects not only this device but all devices using the meter CC.

Installation information How did you install node-zwave-js? Zwavejs2mqtt (dev) docker image

To Reproduce Steps to reproduce the behavior:

1. Go to zwavejs2mqtt settings
2. Click on ‘New Value’ on the bottom left
3. Select a device supporting the meter CC
4. Open the value select - it shows multiple identically named values, unable to distinguish

I see.

What about the following suggestion for a generic label generation:

value: <meterType> <rateType> [<meterScale>]
previousValue: <meterType> <rateType> [<meterScale>] (previous)
deltaTime: <meterType> <rateType> [<meterScale>] (previous time delta)

This would generate the following labels:

value: Electric consumed [kWh]
previousValue: Electric consumed [kWh] (previous)
deltaTime: Electric consumed [kWh] (previous time delta)

Not exactly much shorter, but unique. I’ll collect a few more votes.
