Greetings, Let me introduce myself and what I want to accomplish

Hello, I am trying to bring my wife in the smart home era and get everything to communicate together.

I have the current Smart devices

Tp-Link Tapo wall switches for three lights in the basement
Figidaire Window A/C
Media Windows AC
Hamiliton Beach Alexa Enabled Coffee Maker
Three Alexa Dot’s
Schlage Encode Lock
Eufy Doorbell Camera
GeeniFloodlight with Camera
ADT alarm system (under contract) with Motion Detectors indoors
Two Sonoff Zigbee 3.0 USB Dongle Plus devices

What I want to accomplish is

A) When I go into the basement have my lights turn on. After I leave the basement have it delay 5-10 minutes in case I am returning back to the basement then turn off the lights

B) Add a transmitter to the collar of our cats so we can tell what room they are in so we know if they were accidently closed in a room

C) If I arrive home have the front door unlock itself if I get to the door within 5 minutes of pulling up to the house. My car does have it’s own WiFI access point so I could detect the new network being available possibly.

Future desires

Right now the video from the cameras are saved to a SD card and to view it you need to use the app from each company. I would like to store locally video that only has people and allow my wife to use one program to view both cameras

Hi Emanuel, welcome to the forum!

If you have not discovered the power of HA yet, I can tell you that not much you cannot do with it.
For that, you have to be willing to read, try, ask, fail, learn and maybe invest quite some time in the beginning, depending on your knowledge.
The WAF HAF (Homemates Acceptance Factor) depends on how you go about it: if you go to fast by integrating as much as possible as soon as possible, you might get unhappy faces.
