I've been living in a smart home for two years - and I probably will for the rest of my life

So far, I've loved having control over my door locks through my phone, or through a smart voice assistant like Amazon's Alexa.

The best thing about using smart door locks is checking to make sure you did, in fact, lock the door on your way out. It's given me incredible peace of mind.

Otherwise, locking the doors through the app and smart speakers like Amazon's Echo has been a nice little extra. I basically don't have to physically lock or unlock my doors.

Would I pay for new smart door locks if I moved to a house with normal door locks?

They can be expensive — around $200 for a highly rated model. But for a single door that's the main point of entry, I'd absolutely buy a smart door lock.

Having a smart doorbell with a video camera and microphone has come in handy a few times.

The best thing about the smart doorbell I've been using is the camera and talk-through feature, as well as the video recordings whenever there's activity around the main door.

Having a video feed of my home's main point of entry has been incredibly comforting at times. Checking the feed when you hear a strange noise or an unexpected doorbell ring is unequivocally better than not having the option to check the feed.

One night at two in the morning, my wife was on the iPad and saw a notification that someone had rung the doorbell. Using the doorbell's video and audio feed, I could see that it was the police, and I was able to ask why on earth they were ringing my doorbell at 2 a.m. through the app from bed. Eventually, I crawled out of bed to talk with them, but finding out who's at the door without shouting or letting a visitor know I'm at the door has been invaluable.

It turned out they were checking in, as the officer had apparently seen a "suspicious" vehicle drive into my driveway earlier that day. I'm very appreciative. But ringing the doorbell at 2 a.m.? My wife thought we were getting burgled, albeit by courteous burglars who ring doorbells before they steal your stuff.

Would I pay for new smart doorbell if I moved to a house with a normal doorbell?

For between $100 and $250, yep.

Controlling the temperature from anywhere in the world, including through my phone, has also come in handy.

Personally, controlling the temperature using my phone is more about saving on energy and utility bills more than the convenience. I can turn down the heat or air conditioning from anywhere in the world if I forgot to do it before leaving. I've certainly noticed a drop in energy bills since using a smart thermostat.

The convenience is nice, too. Like door locks, I don't need to physically walk to a thermostat to change the temperature. I've definitely felt lazy doing it, but that's not the smart thermostat's problem.

Some smart thermostats like Nest learn your climate habits over time and can control your home's temperature without you doing anything.

Would I pay for new smart thermostats if I moved to a house with normal thermostats?

Absolutely. Savings on energy bills and more control make the price of a good smart thermostat — between $100 and $250 — worth it, in my opinion.

I've been using a smart alarm and security system that usually costs extra, but it's often optional.

Sensors detect when nearly every door and window in my home is open or closed, and they're all linked to the smart alarm system that's connected to the device's own alarm service. You need that if you want the police to come to your house automatically — without calling them — when there's a break in.

It's been useful to see what doors and windows might be open before setting the alarm, and making sure the alarm is set when you leave.

However, like regular alarm systems that connect to alarm services, smart alarm systems tend to include a subscription that you pay every month or year. Some smart alarm services aren't that much more expensive than a regular service. It depends on how much the regular service charges you.

Would I pay for a new smart alarm and security system if I moved to a house with a normal system?

I'd keep using the normal system at first, as I'd have to get a new smart alarm panel that can cost between $50 and $500.

Smart monitoring cameras have been awful in my experience.

I certainly haven't tried all the smart cameras that are available. And those that I'm using are on the older side, so newer models have surely been improved. However, I almost never use smart cameras apart from the camera on my doorbell.

For reference, the smart monitoring cameras I've tried include the original Canary, Netgear's Arlo Pro cameras, and Vivint's Ping camera.

The main reason why I dislike those I've used so far is that they're terrible with motion detection and notifications. Either they detect everything, including the shade from a passing cloud, or they don't detect anything at all.

If I set the motion detection to a high sensitivity, then I'm constantly bombarded with notifications on my phone. If I set the sensitivity too low, it doesn't detect anything and completely voids the point of using a smart monitoring camera. There's probably a perfect setting, but I haven't found it yet because it requires a lot of tweaking and testing.

Most companies that sell smart monitoring cameras also charge a subscription fee to store all the video clips that the camera records from motion for an extended period of time beyond 24 hours. From my experience, they absolutely aren't worth it, especially the extra subscriptions to store video clips.

Would I install my smart home monitoring cameras if I was moving?

That'll be a big nope. I'd probably give them away or throw them in the trash. I would keep an eye out, however, as I would like some kind of monitoring camera for inside and around the house that handles motion detection well.

There are tons of other smart devices that you can control with an app or online.

A popular entry-level option to get smart homes started is smart light bulbs, which you can turn on and off or even change colors via a mobile app. There are smart appliances, too, and even smart systems for sprinklers and pool machinery. Pretty much anything that can be turned on and off or controlled in some way is getting smarts these days.

Some things I dislike about using a smart home system:

- Some smart door locks and thermostats run on batteries, which need to be replaced, and it can be a pain. Some companies offer a service to replace batteries for you, but they usually cost extra. (Some systems can be hardwired to your home's power or sip power through the climate system's wiring, so watch out for that.)

- Sensor batteries also need to be replaced, but that's the same for normal alarm systems.

- Newer models can get better over time, which means you'd need to buy new smart devices if you want to benefit from newer or better features. It's a bit like smartphones, but with less frequent upgrades. Meanwhile, normal locks and thermostats never go obsolete.

Some smart home services charge a monthly or yearly subscription fee for some of the basic things, like controlling locks and thermostats from an app. Others don't.

I'm getting subscription fatigue where I'm amassing too many services that charge me on a monthly or yearly basis. I'd personally rather pay more up front without a paid subscription for a smart home device rather than pay less up front with a paid subscription. With that in mind, I'd check out smart home devices and systems that don't require paid subscriptions for basic things like controlling locks or temperature through an app, like Ring or Nest devices.

Yet, if a paid subscription is within your budget and you have a specific desire to go for a smart home system like Vivint, ADT, and Comcast Xfinity Home that charge you monthly or yearly for certain basic things, there's no harm in doing so.
