maybe this topic is already discussed here an I simply did not really find the correct answer, but if so please be so kind to just tell me where.
My question is what is the best way to upgrade an existing light switch to a smart one.
It should be able to switch independet of each other from the existing wall switch and via wifi.
As I think there should only be a “box” (whicht might be the real power switch) which reacts to wifi and also to the wall switch. So I want to be able to turn on the light by wifi even if the wallswitch is off.
Is there any cheap solution for this?
If it is not too expensive I could also use a complete solution with the wall switch integrated.
Thanks a lot!
