On/Off works fine but power metering does not show up. Here's a thread successfully adding support to zigbee2mqtt: Koenkk/zigbee2mqtt#19334

You probably need some value convertion.
I haven't set bind/report as Z2M haven't do them, perhaps need it, and no poll too for test, it can be native.

[larskoenig]

Hi! Thanks so much for the DDF. Just tried it and it works! As you said, I had to scale voltage and power by 0.001, but other than that it looks fine. Verified with a smart plug from another vendor and the values are consistent.

[Smanar]

Was lucky, If you can make a PR to submit the device officialy ?
Or share the final DDF (with your convertions) for I make it for you.

[larskoenig]

I've attached the json file with the conversions:
ck-bl702-swp-01(7020).json
What's still missing is power consumption though. I guess it's somehow related to cluster FC57, but I'm not sure how to analyze this further.

[Smanar]

From Z2M this device don't support consumption, you have it in description ? Perhaps its just still missing ?

PR done #7488

[larskoenig]

From the vendor's description of the device, I suppose it supports consumption, and in Z2M it might also still be missing. However, I don't really know how I can help to add support.

[Smanar]

Right, I have read the complete post on Z2M and it seem it's present, but not found yet.
As report are native, you can try to get them in logs.
Can enable deconz log with flag "Info" and "Info_l2", thoses one are easy to understand.
If you see nothing can eanble "ZCL", in this one you will see the request for sure, but not easy to understand.

For me the request need to be a classic reporting on one of the 2 unknow cluster and repetitive.
