Which smart home devices? Hardware selection and configuration with Python

Hello, at the beginning I would like to point out that when it comes to smart home I am green in the subject, but due to the fact that I have a backyard dug up by small renovations, I thought that it is a good time to lay cables for future investments so that in a year's time I will not dig again. I will briefly describe what I have and then what I expect and my idea, maybe one of you can help me:) .

So yes, I own at the moment:

-Synology NAS(camera recording, possibly in the future to run Python scripts on it to control the lights/surveillance)

-2x Reolink Duo 2 PoE camera

-PoE switch max 35W( Currently plugged in 2 cameras which with LEDs on take no more than 20-25W, so there is a power reserve left for Acces Point PoE to the castle).

-30 NOSTALIT 12X12 LED lamps which, according to the specifications on the website, take 6W maximum (I want to divide them into 4 separately controlled sections, arduino control???)

-arduino from previous projects

-Bathroom radio 20W RMS power per channel( 2 channels) I would like to use it to power outdoor speakers

What it needs:

-A voice assistant to control the irrigation of the garden, turn on the camera view on the projector, switch the music outside, control the lighting

-External microphones to listen to my commands in the yard outside the house which I can somehow connect to my voice assistant

-Multiple WiFi sockets which will be switched on/off with the voice assistant

-Acces Point PoE that will cover an open area (10mx10m) without physical obstructions, hanging 3.5m above the ground

-2 weatherproof outdoor loudspeakers of at least 25-30W RMS

- Garden irrigation system (3 separately controlled sections, hoses, connectors and irrigation tips I will take care of myself, I am more interested in help in choosing the controller (arduino will handle the leds and irrigation at the same time??), electro-valves, humidity and rain sensors

-weather station for real-time display of humidity, temperature, etc.

-smartwatch for voice assistant in the house (I plan to place microphones outside)

-lots of cables which I will have to pull underground in conduits (can I use e.g. 5x1mm to control the LEDs via the arduino and divide these 5 wires into 3 separate sections? The distance from the last lamp to the arduino is about 50m)

I would like it to be possible to connect all this with Python( I know it quite well), so that everything is compatible with each other and there is no situation where the Wifi socket does not accept commands from the temperature sensor or something like that 🙂 You know what I mean....

Is this a very complex project in your opinion?

Thanks for any advice and tips!!! 🙂

You are unlikely to get specific answers buy this or buy that.

You'll probably have to decide on some system what will support it all and buy components that will play with that system.

You can put Home Assistant or Domoticz on Synology and even on NodeRed some people build home automation.
