Hi There,
Thank you so much for the quick response!
Ok, so initially I'd like to achieve the following:
Kids room:
When my son goes to bed ( 8yo ) he tends to manually turn on the following things:
- TV + 30min timer
- Xbox for YouTube
- Ceiling light ( turned to blue - his favourite colour )
- Star projector ( Cheap amazon thing - not sure if there is a way to turn this on, but operates with a remote )
- Dumb fan
I'd like to be able to achieve a routine that would accomplish all of this with a single click, as well as automatically turn off when for example 20mins after the TV had gone off - to make my life easier 
Living room:
Pretty much as above really, but with different devices.
I'd like some kind of a scene controller so that when I am off to bed, I can click and it will accomplish something like:
- Turn TV off with 30sec delay
- Turn lights off with 45sec delay
- Turn on the stair lights/lamp - so that I can see where I am going
- Perhaps have some automation to gradually change the lights temperature based on time of the day ( Cooler in the day, warmer at night )
Bathroom:
I've just renovated my bathroom and installed dumb led strips in recesses and a skirting board.
Given there is no window ( bathroom ), I'd like the lights to:
- Be permanently on, but pretty dimmed. Only when someone enters I'd like them to brighten up.
- Extractor fan to turn on when humidity reaches particular level ( I can wire that to a smart plug )
Kitchen:
- Under cabinets lights - same as bathroom, dimmed to "brighter" when motion detected
That's just a few and in theory, I know exactly what to do and how to accomplish it, but I am just so confused with all the zigbee, z-wave, tuya etc. and building a good mesh in general ( 3 storey house )
Given I don't have £1000's to spend, I'd like to avoid mistake and choosing wrong products - ones that will for example kick each other off the network, or perhaps won't play well as extenders ( I know aquara can be picky, but that's about it really )
It is also important to me that there is no significant delay when for example motion is detected or when the light switches are pressed.
I am UK based, with neutral available for the lighting
