Best Affordable Smart Home Devices

A genuinely smart home for around the price of a night out — the cheap speaker, plugs, camera and thermostat that don't feel cheap, with no monthly fees to worry about.

By Stephen V.Last updated How we test

You do not need to spend a fortune to get a home that answers to your voice, runs on schedules, and lets you check in from your phone. The goal of this page is a genuinely smart home for well under $100as a starter set — a speaker to run it, a couple of plugs to automate lamps and appliances, a camera to keep an eye on things, and even a thermostat — without signing up for a single monthly fee. Check each live price as you go, but this is the setup we’d hand someone who’s curious and cautious about the cost.

The trick to a cheap smart home isn’t cutting corners; it’s buying the devices where the budget option is genuinely good and skipping the ones where it isn’t. Multipack smart plugs, a compact speaker, and a local-recording camera all punch well above their price. Every pick below is chosen for value, and none needs a subscription to do its core job. If you want the fuller shopping order, the best smart home devices roundup covers it.

#2Best cheap plug (works with Apple Home too)

  • No hub required
  • Cheap in multipacks

Trade-offs

#4Best cheap camera

Wyze Cam v4 (2.5K)

A camera that records continuously to a microSD card for free and looks far better than its price suggests. It's the honest starting point for anyone who resents monthly camera fees.

Strengths

  • Records to a microSD card with no subscription
  • 2.5K is genuinely sharp for the money
  • Small and easy to place indoors or under an eave

Trade-offs

  • Wired USB power only — you'll be near an outlet
  • Cloud AI (person/package) nudges you toward paid Cam Plus
  • Wyze's track record on security incidents is mixed
Key spec2.5K, microSD recording
SubscriptionNo — works without a plan
Local storagemicroSD up to 256GB
ConnectivityWi-Fi 2.4GHz
PowerWired (USB)
Works withAlexa, Google Home

Worth knowing. The v4 needs USB power, so it isn't a wire-free outdoor camera. For fully wireless, look at the battery picks.

#5Best cheap thermostat

Amazon Smart Thermostat

The cheapest smart thermostat worth owning — built with Honeywell, controlled by Alexa, and often under $80. No frills, but it hits the energy-saving basics for a fraction of a Nest.

Strengths

  • Very cheap, frequently on sale
  • Honeywell-built and reliable
  • Alexa scheduling and Hunches

Trade-offs

  • Requires a C-wire (no adapter in the box)
  • Alexa-only — no Google or Apple

How far a small budget really goes

Start with the brain and the muscle. A compact smart speaker like the Amazon Echo Dot is cheap, sounds fine for its size, and doubles as a basic Mattercontroller, so it runs your voice commands and helps tie other devices together. Add a multipack of smart plugs and you can make several “dumb” lamps and appliances smart at once, for a few dollars each. That combination alone — speaker plus plugs — is a real smart home, and it’s the cheapest place to start.

Which cheap plug: Kasa or Wyze?

Both are excellent value in a four-pack and neither needs a hub. The difference is ecosystem reach. The Kasa Smart Plug Miniworks with Apple Home as well as Alexa and Google, so it’s the safer pick if anyone in the house is on an iPhone. The Wyze Plugis usually a touch cheaper still, but it skips Apple Home — perfectly fine if you’re on Alexa or Google and want the lowest price. Pick on ecosystem, not on pennies.

A camera and a thermostat, still on budget

The budget doesn’t have to stop at plugs. The Wyze Cam v4 records sharp 2.5K video to a microSD card with no subscription — the honest way to add a camera without a monthly bill, as long as it’s near an outlet for USB power. If you want more no-fee camera options, the no-subscription camera picks go deeper. And the Amazon Smart Thermostatis the cheapest smart thermostat worth owning — Honeywell-built and Alexa-controlled — with one caveat: it requires a C-wire and doesn’t include an adapter, so confirm your wiring first (the thermostat guide explains how).

The honest caveats

Cheap is not free of trade-offs, and we’d rather you know them. The Wyze devices are terrific value, but Wyze’s track record on security incidents has been mixed, so use a strong, unique password and keep firmware updated. The budget plugs are Wi-Fi only on the 2.4GHz band, which is fine for a handful of devices but can get crowded if you scale up to dozens. And the cheapest thermostat trades away Apple Home support and a room sensor for its low price. None of these are dealbreakers — they’re just the reasons these devices cost what they do.

Frequently asked questions

Can you really build a smart home for under $100?

For a starter set, yes. A compact smart speaker plus a multipack of smart plugs gives you voice control and automated lamps and appliances for well under $100, and neither needs a subscription. Add a local-recording camera or a budget thermostat as the budget allows. Check the live price on each, since deals move.

What is the cheapest smart plug that's actually good?

The Wyze Plug is usually the cheapest reliable option in a four-pack, and it needs no hub — but it doesn't work with Apple Home. If you need Apple Home support, the Kasa Smart Plug Mini costs a little more and adds it, alongside Alexa and Google.

Do cheap smart home devices require a subscription?

The ones here don't for their core job. The speaker, plugs and thermostat have no monthly fee, and the Wyze Cam v4 records to a microSD card for free. Some devices offer optional paid cloud plans (for example, camera cloud storage), but you don't have to buy them to use the hardware.

Is a cheap smart camera safe to use?

It's as safe as you make it. Budget cameras are fine for most homes, but treat any internet-connected camera seriously: use a strong, unique password, turn on two-factor authentication, and keep the firmware updated. A local-storage camera like the Wyze Cam v4 also keeps footage on a card rather than only in the cloud.
