Yesterday I found Keecker. This is done by a french startup (quite close to the Paris office actually) and is due for this month.
It includes a bright projector, a camera, speakers, some sensors, and is controlled and accessed through a smartphone app.
I can move around in the house.
It’s also very expensive (planned at 1490$ (likely tax excluded) and 1490€ (likely tax included)).
