More than you asked for, but making our house “smart” was my project a few years back!
We have an ancient wired alarm system that still works well, but is not monitored. I have a little Arlo with a sound sensor that I plug in when we’re out of town so I’ll get an alert if it’s triggered. Have a Ring peephole door bell camera. If I had it to do again, I would put in the Doorbell Pro.
Just redid landscaping and went heavy on outdoor lighting (connected to a smart adaptor). Really happy with how it looks and get compliments from the neighbors. Converted all the irrigation to drip … still need to figure out the Hunter app.
Smart lights (not sure what brand, Smart Life is the app) in several places inside.
Other things I added: SmartThings Hub connected to a Nexx smart garage door opener (I always second guess if I closed the gararge door); smart locks on the front door and between the garage & house; leak sensors under fridge, washing machine & kitchen sink. I have a Flume monitor strapped to my water meter that alerts me to unusual water usage and an EcoNet valve robot that can shut off water to the house if a leak is detected and we’re not home. (Can you tell we’ve had leak problems in the past?)
