Recommended smart plug? #441

Closed KrzysztofHajdamowicz closed 2 years ago

KrzysztofHajdamowicz commented 2 years ago

Hey, I'd like to measure few Tradfri and Hue bulbs (mostly GU10), what smart plug do you recommend? Is Blitzwolf SHP-13 OK, or should I look for something better?

nepozs commented 2 years ago

Measuring systems build in most commercially available smartplugs are so similiar, so I can't really reccomend any device… BUT I can recommend only one solution - just measure group of all identical available bulbs.

Sounds like a solution! Does measure script handle talking to group of lights (light group component) instead of single one?

Hi, great you'd like to contribute to the project. As nepozs indicates most smart plugs are between 20 and 50 euro and mostly use similar internal electronics. I am using Shelly plug which is fine. Want to do some more testing with other smartplugs, but did not have the time (and budget) to do so. Some lights have really low current draw when on the lowest brightness settings. You will have problems measuring with any smart plug, than you can use the suggestion of neposz to measure multiple of the same bulb. The measure tool provides functionality for this. But with most lights it will work fine with a single light bulb.

Yes you can input the amount of lights connected. The measure tool will divide the power reading by the amount of lights, to get the consumption for a single light.

I've had problems with GU10 Ikea bulb - it has small power draw when standby and with low brightness (it is main reason why my measurements are stiill not ready, OFC lack of time and additional bulbs also :P )
