I backed the Ninja Sphere on Kickstarter a few years back. I was one of the few who got my hardware, and in the box came a few Zigbee power switches. From recollection, they’re just Ninja Blocks branded versions of the Netvox Z809A.
When I pair them up using my HUSBZB-1, I can see and control the switch portion, but I can’t see anything to do with power consumption. When I had my Ninja Spheres up and running I looked in the app (and / or on the Sphere’s MQTT bus) and saw the power was being reported correctly, so I know the hardware isn’t faulty.
I’m just wondering if power consumption is something HA / Zigbee supports, or if buying different switches to test them out would just be a waste of money.
