The ecosystem has two advantages, the form factor of ordinary sockets and switches can be installed together with ordinary ones if you already have ready-made solutions, and the line is also compatible with non-smart devices in the series. The second is a built-in dimmer, which does not visually distinguish the switch from the rest, unlike most other solutions for the Alice ecosystem. The biggest downside is the price. It is simply not real against the background of competitors. But on the other hand, if you have three switches at the entrance to the room, there is no other solution.
