Buttons on this page are Amazon affiliate links: if you buy, Quiet Switch may earn a commission at no cost to you. Nobody pays for a position. How this works.
The best smart home devices under $100 do a job every day: the Amazon Smart Plug for an Alexa home, the Wyze Cam v4 for a porch or garage, Amazon's thermostat for a rental, and the SwitchBot Curtain 3 for a bedroom window.

It is set up and managed inside the Alexa app, so there is no extra brand account to create.
The body is compact enough that the second outlet in the wall plate stays free, per Amazon's listing.
Amazon says it reconnects to Alexa on its own after a power or Wi-Fi outage, which is the failure that makes people unplug cheap plugs for good.
Skip this ifAlexa only, and the listing mentions no energy monitoring. If anyone in the house uses Google Home or Apple Home, buy a Matter plug instead.
A porch, driveway or garage where a light and a siren that fire on motion are worth more than a sharper picture.

Records to a microSD card of up to 512 GB with no monthly fee; Wyze's Cam Plus cloud plan is optional rather than required.
Motion triggers a built-in spotlight and a siren, and the listing says person, package, pet and vehicle detection runs on the camera itself.
The magnetic base and freestanding stand mean an indoor placement needs no drill, which suits renters.
Skip this ifIt joins 2.4 GHz Wi-Fi only, outdoor use needs a weatherproof power adapter sold separately, and there is no Apple Home support. Power cut? It stops recording, because there is no battery.
A rental, a second property, or anywhere the thermostat needs to be smart but not clever.

Price
Entry level
It is the entry-level option and still delivers most of the actual saving, which comes from scheduling rather than intelligence.
Energy Star certified, and Amazon points buyers to local utility rebates after purchase — check yours before paying full price.
Nothing to learn. It sets a schedule and holds it.
Skip this ifAlexa only and no Matter, and room-by-room comfort depends on owning Echo devices that report temperature. A mixed-platform household will outgrow it.
Renters and anyone who does not want to replace perfectly good curtains to automate them.

It clips onto the curtain you already own, so this is the only automation here that leaves no trace when you move out.
An optional solar panel, sold separately, keeps it charged on a sunny window and removes the recharging chore.
Opening the bedroom curtains on a sunrise schedule is the one automation that most people keep using after the novelty wears off.
Skip this ifHeavy blackout curtains on a stiff rail will defeat it, and on its own it only talks Bluetooth to a phone nearby: Alexa, Google, Apple Home and control away from home all need a SwitchBot hub.
Smart home prices swing more than most categories, and big sale events regularly bring speakers, plugs and cameras well below their usual price. The useful habit is to decide what you need first, then buy it when it drops, rather than buying whatever happens to be discounted.
Two things are not worth chasing at any price: Wi-Fi devices that only work in an app you have never heard of, and anything that needs a subscription to do the job it is sold for.
FAQ
Questions people ask
What is the best smart home device under $100?
For most homes, a Matter smart plug or two. For an Alexa household, the Amazon Smart Plug. For security on a budget, a camera that records locally, such as the Wyze Cam v4.
Can you build a smart home for under $100?
A useful starter set, yes: a speaker, a plug and a leak sensor fit comfortably. A whole home does not, because locks, thermostats and robot vacuums cost more on their own.
Why are there no prices on this page?
Prices change too often to print accurately, and Amazon's rules require live pricing. Each button opens the current listing.
