My wife is nearly home. System alerts me. I quickly tidy my day’s mess. She doesn’t need that after a big day.

She arrives. Gate opens for her automatically.

As she approaches the door, the light turns on for her.

Her night time play lists starts on low volume, overriding mine.

A leopard approaches the house. The house robot with bolt on subscriptions, (the expensive “hunt and defend” add on), wreaks carnage on said leopard, only to find it was a child trick or treating. Lawyers for subscription bot are arranging payment to child’s family for their lost family member.

All in all, it’s really useful.

In addition to all the automation everyone has talked about, some of us are also data nerds.

I enjoy knowing the temp, air quality, etc. in every room. How does this change throughout the day/season? Did leaving this door open or this fan on improve anything? What can I automate at what threshold to improve things?

You can also get a lot of data about energy usage too. And if you have solar and battery, it’s neat seeing how much it affects and how much you save.

Automation is useful, but in the end it’s just a hobby like many other things. It’s fine to be into it or not into it.

In short, enlightened laziness.

I can turn the bedroom lights on and off, from my bed.

I can turn the bathroom light off, after my young daughter left it on, in the middle of the night.

My livingroom lights colour shift, to keep my family’s sleep cycle in vague check.

I can turn my heating down room by room, if it’s not needed. Conversely, I can preheat the house, on the way home.

While the setup took a bit of prep work, it’s now highly reliable, and makes my life a lot easier.

So many reasons.

Smart locks on doors that disarm house alarms when they’re unlocked with a code. Lights that turn on when someone is in a room, and off when the room is empty. The garage door alerting you that it’s still open around the time you go to bed. The house stereo turning itself off at a certain time on weeknights, and the house alarm system turning itself on at the same time. Being able to check that the gas fireplace is off after you’ve driven out of your neighborhood on your way somewhere. The house disabling the security system for 20 minutes when it detects you on the second floor landing, so that you don’t trip the motion sensors when you go down for a snack.

A non-trivial example of some more complex things our house does: when one of our phones enters the neighborhood, and it is after dark, our carriage and porch lights come on. If no other phones are already home, some of the inside lights also turn on. When we turn onto our street, the garage door opens. After the garage door is closed, the outside lights turn off.

Any number of things ranging from small to large conveniences. Some small conveniences become large ones when you have guests staying over.

Edit: ooo, ooo, one other thing: I have a bunch of these switches around the house that have multiple buttons and are programmable (they recognize single click, double click, hold, etc). It allows me to hook almost any part of my house to any switch, without rewiring everything. I have several configured to turn off the alarm system, I can manually turn off all of the first-floor lights from the upstairs master, I have one in the entryway set to toggle a lamp in the office to avoid having to walk in there, navigate around the desk to the far side of the room, and switch it from there. I configured one to turn the gas fireplace on and off, because the builders had not seen fit to wire the controls to a wall-switch.

30% reduction in heating cost without reduction in comfort.

Convincing we’re-home-simulation while gone.

Each single light is independently dimmable, making for variety in light scenes for different purposes.

Lights are really nice. With one voice command I can turn the entire house into a bright daylight, or drop it to low intensity red shift at night.

My thermostat warms my room up before I awaken so I won’t be cold getting out of bed, while my lights slowly fade on over 10 minutes before my alarm, waking me before the tone sounds most days. At bedtime, I can fade off all the lights in the house at once before going to sleep.

Also, I can turn on the color effects and throw a dance party for the family.

Well, it’s a hobby/passion. Simple as that. I’m a nerd, i love such things. And home automation is a thing I’ve dreamt of since the first automatic door in star trek. Automatic lights, alarm-system, cameras, a smart AI (locally, no stupid alexa et al),a tablet at the door which tells us everything we want to know on a quick glance (weather, shopping-list, fuel-prices, status of all machines etc). And all that with some many thousand lines of code and triple redundancy 😍

When i visit other people I actually find it “retro” to use light-switches 😁

A different take from a different person.

Accessibility for my disabilities, able to have the lights turned down when I have a migraine and can’t get up because of pain, as well as reminders and timers with just my voice. Automation helps with my disabilities too.

I personally don’t have any of that but here’s what I would like to use it for. When I go away for, say, two weeks, I’d like to be able to randomly flick lights and TV on and off in my apartment to seem like someone’s home. Currently I do it by plugging floor lamps into timered power socket controllers, but they aren’t internet enabled so all I can do is program them to come on and off at specified times during the day, which an observant burglar could figure out.

I would also like to save on gas bills and turn the heating off when I go away. But if it’s winter time and I go away for 2 weeks, I hate coming back to a cold flat that take ages to warm up to comfortable temperatures. I’d like to be able to turn the heating off when I leave, and then back on, say, a whole day before I come back.

I have ADHD. It’s easy for me to forget something in my routine. So I’ve set up many of my routines to be automatic or controlled with a single voice command.

When I wake up to my alarms, my lights start turning on gradually at a dimmer setting and blue. Then they turn white at full brightness to really wake me when it’s time. When I leave for work, I simply say “I’m leaving” and my lights all set themselves appropriately. I even have certain things like space heaters on a smart switch and they automatically turn off when I’m not home in case I forgot to manually shut them off.

Then when I get home, instead of needing to hit a bunch of switches for all of my various lights, I simply say “I’m home” and in 15 seconds everything does for me what would have taken me 5 minutes manually. By the time I have my shoes off, my house is already ready for me.

When I go to bed, it’s the same. A simple “goodnight” turns my TV off, turns my fan up, and turns the lights off, all with me not having to get out of bed.

When I do laundry, my phone gets a notification when things are done. I’m able to plan my cycles more efficiently and do things like run an errand and be able to be back just in time to swap loads. When there’s an error, instead of “E43” or some nonsense on the screen that I need to lookup and is still vague, I get a notification in the app that says “Error: Washer unbalanced. Please check load and restart” and actually helps me.

If a fire alarm goes off in my house and I’m not home, my security cameras will pick up the noise of the alarm and send an urgent push notification to my phone. I can check in and see if someone just burnt food or if there is an actual emergency.

I could go on. I’ll admit that being tied to google/Amazon isn’t ideal and you should use something like HomeAssistant instead so you have complete control. It’s just a steeper learning curve, is all. But regardless, you want a home from The Jetsons? It’s already here. Not perfect mind you, but in large parts it’s already obtainable and really not that expensive. Just swap a bulb/switch here and there.
