Lighting controller with dimming, power measurement and iOS/Android support

Welcome,

Is there a controller on the market that would allow lighting to be controlled as follows: on/off lighting, checking power consumption, dimming and brightening (to be mounted in a switch)? And communication with iOS and Android.

Sure e.g. FIBARO, read up....

There are bleboxes operating over wifi, but I don't think they have power consumption. Instead, they can be completely autonomous - in contrast to Fibaro, which is scenatrised.

Fibaro too expensive and the bleboxes as you rightly pointed out have no power consumption.
I guess I will have to go to plan B.
What would be the total cost of building such a controller? Is there anyone on the forum who could undertake such a task?
I know there will probably be a few wise ones in a moment who will write to use off-the-shelf solutions why bother etc. If the business works out the device would be produced on a large scale, but I need to get an idea of the costs first. I have also oriented myself with Chinese solutions, they are very cheap but there is no documentation, API, SDK etc.
