I have one of these so I could measure it. But my plug is not very accurate.

my plug is not very accurate

I was referring to the Fibaro plug. I have a Shelly plug as well.

3 bulbs connected in parallel, measured by Blitzwolf SHP-13.
'Power' measurement was updated VERY rarely and had weird readings at low consumption so I created new template sensor to multiply current*voltage.

[bramstroker]

I'm afraid you cannot just multiply current * voltage, as there is also power factor to account for, which smart plugs also calculate.
Now you are assuming power factor 100 which is never the case for lights.

Maybe @metbril will be able to take measurements, so it can also be compared.

[KrzysztofHajdamowicz]

It was a problem in my case, power was sent as integer, so almost no resolution when brightness was smaller than 70%.

[metbril]

I should be able to measure the light with my Shelly plug once the plug is no longer managing my Christmas lights. 😉

[bramstroker]

Thanks a lot.

[metbril]

Please move the topic to planned measurements?

[bramstroker]

Yes moved

[metbril]

I haven't found the time yet but don't worry.

3 bulbs measured via Shelly Plus 1PM. I might buy more GU10 sockets to measure 10 of them in parallel.

[bramstroker]

@KrzysztofHajdamowicz Great job! measurements looks very good to me. You can do 10 of them, but imo 3 is good enough.
You did set the option in the wizard which asks for multiple lights to 3, right?

[KrzysztofHajdamowicz]

Yeah, I set it.

10 of them might help in getting a better resolution in lower brightness values. Anything less than 2W total power draw resulted in very noisy reading (basically flapping between 0 and 0,x W every second), I guess it was in the middle of some filter.

[bramstroker]

Yes than it would be a good idea to add some more. To reduce noise in the lower brightness levels.

I did plot it using some online tool, and looks really good already.

[KrzysztofHajdamowicz]

OK, so I'm giving up on measuring 10 of them. I would be glad if you include it in next powercalc release! 🎉
