That probably would work well for those closer to the equator.
But for those in the 100 minutes zone of this map that would mean going to work at 6:30am in the summer (assuming we are using civil twilight as “sunrise”), and 9:30AM in the winter which is much more of a swing than daylight savings puts on us, but at least it is a gradual one.
For those above the Arctic Circle, they just work 24/7 for a couple of weeks in the summer but get a similar time off in the winter ;)
The switches don’t have to control the lights they are wired to. I have Inovelli z-wave switches, and on these you can disable the relay. So the switch can still send out commands/scenes on the network but the relay is always on.
Then you would put in a relay unit in the electrical box of the lights or if you have enough room in with the switches. Then setup the switches to control their respective sets of lights.
Might even be a switch out there that lets you disconnect the relay from the buttons on the switch but still control the relay which would cut down on the device count.
