I found 4 smart plugs for 20€ each and i bought them since i’m not really a fan of ikea in general.
They work like any other hue lamp and i can turn them on and off líke a light!
The answer to this thread is: YES, the HUE integration works with the smart plugs!
I think Philips configure it as such.
In the Philips Hue app, it is also put in the category “lights” instead of “accessories” and Philips states that the plug should be used only for lights.
Just letting you know: I just bought Osram Smart Plugs and they all work perfectly fine using the Hue Bridge. Only Issue for now: They show up as “LIGHT.Osram_1” instead of like: “SMARTPLUG.Osram_1”, while I have yet to figure out, what the right prefix would be for smartplugs.
