Not the advice you were seeking, but social media is all about unsolicited advice so...
For the most part, the only people who are impressed with a smart home setup are geeks like us.
I've sold two houses in the last couple of years, one was our residence and another that was my former house that we turned into an airbnb. Both were automated with HE, a Qolsys alarm system, smart door locks, smart thermostats, smart bulbs, the whole 9 yards.
I took it all out. Every last bit of it. Much of it didn't have any value to me, for example a lot of GE z-wave 500 series switches, ring cameras and doorbells (which I grew to despise), and other things I really didn't want to use in our new house. I replaced every switch and bulb with dumb ones and the thermostats with the most basic non-programmable ones I could find at Home Depot.
In our residence, I took everything out before it went on the market, which was a good decision because the buyers couldn't even figure out where the water shutoff was. In the airbnb, it was only on the market for a few days before it went under contract and I hadn't removed everything yet. I asked the buyers if they wanted any of it and it was a hard no, with no hesitation.
My (unsolicited) advice: unless you are certain that most people who will be interested in your property are home automation geeks (and your realtor agrees), take it all out and save yourself a lot of headaches. Do you really want to be doing tech support for the buyers forever? It won't stop there, every little issue they have with the property will become your problem. Take the check at settlement and be done with it, and invest your time into your new house.
For cameras (in your new house
) you can't go wrong with Ubiquity. They have cameras across a wide range of prices and they do a pretty good job of recognizing people, vehicles, animals, etc. You do need to invest in their ecosystem, but that's one decision I definitely don't regret for a second.
