Make Deako entity domain ‘switch’ instead of ‘light’.
Having Deako recognized as ‘switch’ will allow to change domain to fit the use case. For example, smart switch could be used as fan or some other stuff and not only for light. In fact ‘switch’ is indeed what this is but not light.
It is always a good idea to provide “proof” of your statements.
The next developer that looks at this FR might not know the product at all.
Perhaps the clue is in the name “Deako Smart Lighting”
If you look at the link I provided, then It is in fact light switches.
There do not seem to be any bulbs or lamps a available.
How do you incorporate the concept of a dimmer in the switch domain?
And a motion sensor. 
In all circumstances it is still not lights.
Hold the bus. The Deako integration was only introduced in 2024.10.
IIRC a new integration can only introduce one domain in it’s first release. Others can be added later. So, more may be coming.
I did not know that, but still light looks like the wrong one anyway.
