I have some Centralite Smart Plugs, but some does not show power consumption, The documentation reveals it have power monitor, but no device handler can get the correct data.
The common error was
Read attr: read attr - raw: D615010B04060B0586, dni: D615, endpoint: 01, cluster: 0B04, size: 06, attrId: 050b, result: unsupported attr

SmartThings has eneabled Over the Air (OTA) firmware updates, I have enabled (because its disabled by default) and surprisingly the device was updated
now my device its Current Version: 0x16015010
Power its working, the raw description has not updated, but works fine, if you uninstall and install the device, the raw description is updated , but its not necessary to working fine.
The device handler I use its ZigBee Switch Power, its original from SmartThings, it update the power with every change
If you have a centralite device with no working power monitor, try to eneble OTA updates
