You're right, totally forgot about that
Even if this Plug is working fine 110%, I'm sure I won't replace every module I have with this one.
What does it add, that's the question you'll always have to ask yourself. An example of that, what does half a second (or even 10 seconds in this case) of improvement in responsiveness
really add to your lighting when all you do is switching lights event-driven based on whether it's dark or light outside? Absolutely nothing. You won't notice the difference.
But I think it's good that they are available and I think they can be a good solution for places where all those other bigger modules won't fit or for those places which are too 'visible'. IMO the size & looks are the 2 the biggest advantages, price is indeed a disadvantage.
