A few years ago, I moved into a small apartment with big dreams of turning it into a futuristic haven. I pictured voice-controlled lights, a thermostat that knew my schedule, and maybe even a camera to keep an eye on my mischievous cat while I was at work. But my budget? Let’s just say it was more “ramen noodles” than “smart home showroom.” I quickly learned that building a smart home doesn’t have to mean breaking the bank. With a little research and some clever shopping, I discovered a treasure trove of smart home gadgets under $100 that transformed my space into something both functional and fun. If you’re looking to dip your toes into the world of smart home tech without draining your savings, this guide is for you. Let’s explore how affordable devices can make your home smarter, safer, and more convenient, all while keeping your wallet happy.
Why Go Smart on a Budget?
The idea of a smart home used to feel like something out of a sci-fi movie—exclusive, expensive, and out of reach for most of us. But in 2025, smart home technology has become more accessible than ever. Affordable gadgets now offer the same core features as their pricier counterparts: voice control, app integration, and seamless connectivity with platforms like Amazon Alexa, Google Assistant, and Apple HomeKit. These devices don’t just add convenience; they can save energy, enhance security, and even bring a little joy to your daily routine. Whether you’re a renter looking to upgrade without permanent changes or a homeowner wanting to test the waters, there’s a gadget for you. Let’s dive into the best smart home devices under $100 that deliver big value without the big price tag.
Smart Plugs: The Unsung Heroes of Automation
When I first started my smart home journey, I was skeptical about smart plugs. They seemed too simple to make a difference. But after plugging my coffee maker into a TP-Link Kasa Smart Plug Mini, I was hooked. For around $25, this little device turned my morning ritual into a hands-free experience. With a quick voice command to Alexa—“Turn on the coffee maker!”—my brew was ready before I even stumbled out of bed. Smart plugs are the perfect entry point for beginners because they’re affordable, easy to install, and incredibly versatile.
These devices let you control anything plugged into them—lamps, fans, holiday lights—via a smartphone app or voice assistant. The Kasa Smart Plug Mini, for example, connects to Wi-Fi and works with both Alexa and Google Assistant. You can set schedules to turn devices on or off automatically, which is great for saving energy or creating the illusion that someone’s home when you’re away. Some models, like the Wemo Mini Smart Plug, even monitor energy usage, helping you identify power-hungry appliances. At under $30, these plugs are a budget-friendly way to make “dumb” devices smart.
Smart Speakers: Your Home’s Command Center
No smart home is complete without a smart speaker, and thankfully, you don’t need to splurge to get one. The Amazon Echo Pop, priced around $40, became my go-to for controlling my growing collection of gadgets. Its compact design fits perfectly on my kitchen counter, and the sound quality is surprisingly robust for streaming music or podcasts. Smart speakers act as the brain of your smart home, letting you control compatible devices with voice commands. Want to dim the lights, check the weather, or set a timer for your oven? Just ask.
If you’re Team Google, the Google Nest Mini, often available for under $50, is another excellent choice. It offers crisp audio and seamless integration with Google Assistant. For Apple users, the HomePod Mini, occasionally discounted to around $99, delivers stellar sound and works with Siri and HomeKit. Each of these speakers supports major smart home brands, so you can mix and match devices without worry. My tip? Choose a speaker that aligns with your existing ecosystem—Alexa, Google, or Siri—to ensure smooth compatibility.
Smart Lighting: Set the Mood Without Breaking the Bank
Lighting can make or break the vibe of a room, and smart bulbs are an affordable way to elevate your space. I swapped out my old bedroom bulb for a Govee Smart LED Bulb, which costs about $15, and suddenly I had a rainbow of colors at my fingertips. With a quick app tap, I could switch from bright white for reading to a warm amber glow for winding down. These bulbs connect via Wi-Fi or Bluetooth and work with Alexa and Google Assistant, letting you control brightness and color with your voice.
For those who prefer a more permanent setup, the Lutron Caseta Smart Dimmer Switch, priced around $60, is a game-changer. It replaces your existing light switch and lets you control lights (even non-smart bulbs) via an app or voice assistant. Unlike bulbs, it doesn’t require a hub, making it ideal for renters or anyone avoiding complex installations. Smart lighting not only adds ambiance but can also save energy by letting you schedule lights to turn off when you don’t need them.
Security Cameras: Peace of Mind on a Budget
One of my biggest concerns as a pet owner was wondering what my cat, Luna, was up to while I was at work. Enter the Wyze Cam v4, a $36 indoor/outdoor camera that delivers 1080p HD video, night vision, and motion detection. Setting it up took minutes, and now I can check on Luna (usually napping on the couch) from my phone. Affordable security cameras like the Wyze Cam or the Blink Outdoor, both under $100, offer features typically found in pricier models, like two-way audio and cloud storage options.
For front-door monitoring, the Blink Video Doorbell, priced at about $60, is a fantastic pick. It provides live video feeds, motion alerts, and two-way audio, so you can chat with delivery drivers or scare off porch pirates. These cameras integrate with Alexa or Google Assistant, making them easy to control alongside other devices. If you’re looking to boost security without a hefty investment, these budget-friendly options deliver serious peace of mind.
Smart Thermostats: Comfort and Savings Combined
Heating and cooling can eat up a chunk of your budget, but a smart thermostat can help you save without sacrificing comfort. The Google Nest Thermostat, often available for under $100 during sales, learns your schedule and adjusts temperatures to save energy. I installed one in my apartment and noticed my energy bill drop because it automatically lowered the heat when I was away. Plus, being able to adjust the temperature from my phone while cozy in bed? Priceless.
Another solid option is the Emerson Sensi Lite, priced around $90, which offers similar features and works with Alexa, Google Assistant, and HomeKit. Both thermostats are easy to install (no electrician needed for most setups) and provide energy usage reports, so you can see exactly how much you’re saving. If you’re renting, check with your landlord before installing, but many models are renter-friendly and reversible.
Smart Locks: Secure Your Home with Ease
Forgetting to lock the door used to be my biggest anxiety—until I got the Wyze Smart Lock, priced at about $90. This retrofit lock fits over your existing deadbolt, so there’s no need to replace hardware, making it perfect for renters. I can lock or unlock my door from anywhere using the Wyze app, and I love creating temporary codes for guests or dog walkers. It also integrates with Alexa for voice control, though you’ll need a separate hub for full functionality.
Another great option is the SwitchBot Lock Pro, which costs around $80 and boasts a long battery life. Smart locks add convenience and security, letting you monitor who’s coming and going without fumbling for keys. Just make sure to check compatibility with your door and smart home ecosystem before buying.
The Bigger Picture: Building a Cohesive Smart Home
When I started mixing and matching gadgets, I quickly learned the importance of compatibility. A smart home is only as good as its ecosystem, so stick with devices that work with your preferred voice assistant or platform. For example, if you already own an iPhone, HomeKit-compatible devices like the HomePod Mini or Wemo Smart Plug will feel seamless. If you’re an Android user, Google Assistant devices like the Nest Mini or Nest Thermostat might be your best bet. Alexa is a great middle ground, supporting a wide range of third-party devices.
Another tip? Start small. You don’t need to overhaul your home overnight. Begin with a smart plug or bulb to get a feel for automation, then gradually add devices as your budget allows. Many of these gadgets are often discounted during sales like Amazon Prime Day, so keep an eye out for deals to stretch your $100 even further.
Real-World Impact: How These Gadgets Changed My Life
Before smart home tech, my mornings were chaotic—rushing to turn on lights, brew coffee, and check if I’d locked the door. Now, my Echo Pop wakes me with a gentle alarm, my Govee bulbs cast a soft glow, and my coffee maker hums to life—all before I leave my bed. When I’m away, the Wyze Cam keeps tabs on Luna, and the Nest Thermostat ensures I’m not wasting energy. These small changes have made my home feel more like a sanctuary, and the fact that I spent less than $300 to achieve it feels like a win.
Beyond convenience, these gadgets offer practical benefits. Smart plugs and thermostats have cut my energy bills, while the Blink Doorbell gives me peace of mind when I’m traveling. Even my friends, initially skeptical of “fancy tech,” now ask me how to set up their own smart homes after seeing mine in action.
