Hello Daniel
Congratulations to your new Project. I’ve finished nearly the same in April (but located in switzerland).
Maybe you can find some hints in my questions / post (House Renovation)
I recommend you to place some switches to ist traditional places. On one hand its for visitors, and on the other its for failback Szenarios. With fibaro dimmers for example, you can use them as smart input devices (1x click, 2x click…).
As you can read in my post, I’ve decided to go with zWave as main Technology. Ist more reliable and seperated from the attackable wifi (of corse its also attackable, but with much more Technology needed).
Take a look at LED Stripes for lighting. Especially RGBW stripes make wonderfull light.
Good luck with your Project.
If you like to get further information, feel free to contact me.
regards
Michael
