I think voice assistants are bolt ons to an ecosystem, they don't need to define it. I use Alexa but I'd say my 'core' is Philips Hue. I then have an old Dell terminal PC that cost 30 quid running home assistant which brings everything together.
Cameras are Reolink and they have a great selection including subscription free door bell.
Cheers, i guess since i'm mostly starting from scratch rather than previously adding various things at various times and ending up with a mishmash, i'm trying to structure logically and try and play things out, rather than ending up with another mishmash or trying to force things to integrate.
I get that Google/Alexa is probably pretty much the same, and it makes sense to stick with Google so i can maybe keep the odd small puck style speaker for the odd room.
I've already got the Hue hub, so i know that's likely the basis for my lighting. I'm eyeing up Shelley switches for most switches/sockets etc which i think plays ball with the Hue hub.
My concern with camera/doorbell, is i want them wired this time as i'm not sure on Wifi coverage everywhere given the size of the plot. I'm also going to have an electric gate and need an intercom along with a switch to remotely open the gate. The builder says he includes this in the build, but i need to make sure it integrates.
I think my wishlist is
Lighting - Hue hub/bulbs already owned. Just need to spend a small fortune on
Switches/Plugs - Aiming for Shelley stuff. They come in black which my wife wants and pricing seems decent
Music - I've go down this route after. I've a Raspberry Pi with a big enough SD card to store all my home music. Then i can cast Spotify to it. Just need a multi channel amp
Cameras - Unsure. I was fixed on the Unifi stuff as i've got their Dream Machine router which has a built in NVR, but smart capability doesn't seem great and has various workarounds via HA and unsure how reliable it is
Doorbell/Gate - As above. Unifi doorbell seems logical
Electric Shutters/Blinds - Unsure of brand, but i've stressed they have to be HA compatible to the builder
Heating - Ducted split hot/cold system. Unsure of controller brand, but again have stressed it needs to be HA compatible
Front Door Lock - Would also like this to be wifi controlled if possible. Seems there's a few out there now. Last time i looked only Yale did one and it wasn't great.
Also need to setup some kind of wall mounted control panel/screen where i can access everything and ideally be the focal point for the Intercom.
