Add support for Electrical Measurement (0x0B04) and Smart Energy Metering (0x0702) clusters for LEDVANCE Smart Plugs

[amitjoy]

Is your feature request related to a problem? Please describe. I’m currently unable to access energy monitoring features of LEDVANCE Smart+ ZigBee plugs because the Electrical Measurement Cluster (0x0B04) and the Smart Energy Metering Cluster (0x0702) are not supported by com.zsmartsystems.zigbee.ZigBeeDeviceType. These clusters are crucial for retrieving power consumption and energy usage data.

Describe the solution you'd like I would like the ZSmartSystems ZigBee library to support the following clusters:

1. Electrical Measurement Cluster (0x0B04) – for measuring active power, voltage, and current.
2. Smart Energy Metering Cluster (0x0702) – for tracking cumulative energy consumption.

Adding these clusters will allow LEDVANCE Smart+ plugs and similar devices to report real-time power usage and cumulative energy data within openHAB.

Describe alternatives you've considered NA

Additional context

• Device: LEDVANCE Smart+ Plug (ZigBee version)
• Manufacturer: LEDVANCE
• Clusters to be supported: - Electrical Measurement Cluster (0x0B04) - Active Power (0x050B) - RMS Voltage (0x0505) - RMS Current (0x0508)
  • Smart Energy Metering Cluster (0x0702) - Current Summation Delivered (0x0000) - Instantaneous Demand (0x0400)

This feature would allow users to fully utilize energy monitoring capabilities within openHAB, enhancing automation and energy management.

Strange - these clusters have been supported for a very long time. We've even had a smart energy product go through certification.

You mention openHAB - some attributes of these clusters are already supported (for a long time) in openHAB - this includes the attributes that you have mentioned above (I think maybe RMS voltage isn't implemented in openHAB, but I believe all the others are, and have been for many years).

You’re likely familiar with the zigbee nodes command in openHAB. This command lists only those nodes from LEDVANCE that are defined in the com.zsmartsystems.zigbee.ZigBeeDeviceType enum, even if the aforementioned clusters are supported by LEDVANCE SmartPlug. Am I overlooking something?

[cdjackson]

Probably the console has added support for these clusters - it is certainly limited. You'd need to add them as locally supported clusters.
