A rented apartment where the owner wanted proper lighting control without rewiring anything or losing the deposit.
We used smart dimmer modules behind the existing switch plates, so every wall switch still works exactly as before for anyone who does not want to use an app. Under-cabinet lighting was added in the kitchen on its own circuit.
Scenes cover cooking, dining and evening, each reachable by voice or a single tap. Everything is reversible at the end of the tenancy, which was part of the brief from the start.
