Hello, we are planning a new build and would like to have a smart lighting control system. What we have in mind are spots and other light sources distributed throughout the house. I will describe an example based on the kitchen/dining area to illustrate what we imagine:
Spots distributed in the kitchen and dining area, plus a pendant lamp over the dining table. Indirect lighting (e.g. kitchen plinth), + other light sources in the form of table or floor lamps.
All lamps should be switchable individually (on/off) and dimmable (bright/dim), and the color temperature (cool/warm white) should be adjustable.
Several light scenes should be able to be set and saved.
e.g.:
Cooking light scene: all lamps in the kitchen area bright cool white
Cozy dining light scene: kitchen area dimmed, pendant lamp warm white and dimmed to bright, indirect lighting warm white bright.
+ other light scenes
It should be possible to switch everything at one switch (+scene change) and via voice control/app.
Even in case of system failure (radio), it should be possible to turn on the light via switch.
Which system is recommended to realize this?
What costs can be expected?
So if the whole thing is supposed to be conventional electrical wiring, it could possibly also be solved with Shellys. Here switching should still be possible in case of radio failure.
For the scenes, you would take, for example, a Shelly I4 WiFi switch. It can switch various scenes.
For the lamps, you need either Shelly 1 or 2.5 or Shelly Dimmer 2 as actuators for lights and sockets. You need deep boxes or, I guess, a sub-distribution or something like that in the living room.
Estimates for a living room: 15 actuators. Cost per Shelly actuator about €30. Wiring about €15. Deep boxes and sub-distribution €300? = €975 per living room additionally. Plus your own time to configure scenes and Shellys.
Shellys can also be integrated via skills through Alexa etc. The app is also available or quite easily integrated through Home Assistant.
But I would get several opinions on this.
