What Does a Smart Home Cost to Run?

The price on the box is a one-time number. The one that actually decides whether a smart home is cheap or expensive is the one nobody prints: what it costs you every month after you’ve bought it.And here’s the thing — that number is almost entirely up to you, because nearly all of it is optional subscriptions rather than unavoidable running cost.

The two real costs: subscriptions and electricity

A smart home’s running cost splits into two buckets, and they’re wildly different in size. Electricity is tiny.A smart plug, a bulb, a speaker, a camera — each draws a few watts, adding up to a handful of dollars a year across a whole home. A smart thermostat can even make you money back by not heating or cooling an empty house, a saving both the U.S. Department of Energy and ENERGY STAR attribute to sensible setback schedules.

Subscriptions are the whole ballgame.Cloud camera storage, a video-doorbell plan, professional alarm monitoring — these are the fees that turn a “cheap” device into an expensive one over five years. The good news is that most of them are avoidable.

Two smart homes, side by side

Here’s the same set of devices — a couple of cameras, a video doorbell, an alarm — run two ways: one leaning on subscriptions, one built to avoid them. The figures below are illustrative examples to show the shape of the difference; actual plan prices vary by brand and change over time, so confirm current pricing with each provider.

Over five years, that gap is the difference between spending well over a thousand dollars in fees and spending almost nothing — for hardware that does the same job. That’s not a rounding error; it’s often more than the cameras themselves cost.

How to keep it near zero

Three choices do almost all the work:

• Buy local-storage cameras. A camera that records to a microSD card or a base station (Wyze, Tapo, Reolink, eufy) has no cloud fee, and the footage stays on your network. Our no-subscription cameras page is the whole list.
• Pick a doorbell with local storage. Cloud-only doorbells (like Ring) need a plan to save clips; a eufy doorbell records locally for free.
• Self-monitor your alarm. DIY systems let your phone be the alarm at no cost; professional dispatch is an optional add-on, not a requirement. See the no-subscription systems.

When a subscription is actually worth it

None of this means subscriptions are a scam. Professional alarm monitoring buys a staffed center that calls for help when you can’t — genuinely valuable if you travel a lot or sleep through your phone. Cloud backup protects footage if a thief takes the camera. The point isn’t “never pay a fee”; it’s pay for the ones you actually benefit from, and don’t get talked into the rest. Add up the yearly number before you buy, and the smart home you build will be the cheap one to live with. For the security-specific breakdown, see how much a home security system costs.
