Affordable Smart Home Upgrades Under $100
You don’t need to drop a paycheck to make your home smarter. In fact, some of the most impactful upgrades cost less than a nice dinner out. Whether you’re a renter or a homeowner, these affordable smart home upgrades under $100 can improve convenience, security, and energy efficiency—without breaking the bank.
I’ve spent years testing gear in real homes, and I promise you: You don’t need a hub, a subscription, or a tech degree to get started. Let’s walk through the best budget smart home devices you can buy right now.
1. Smart Plugs: The Easiest Entry Point
Smart plugs are the gateway drug of home automation. For around $15–$25, you can turn any dumb appliance into a smart one. Plug in a lamp, a coffee maker, or a fan, and control it with your phone or voice.
I use a Kasa Smart Plug in my living room to schedule my floor lamp to turn on at sunset. It makes the house feel lived-in when I’m traveling. Most models work with Alexa and Google Assistant, so you won’t get locked into one ecosystem.
These are perfect if you want to dip your toes into cheap home automation without any wiring or commitment. Just plug, pair, and go.
2. Smart Bulbs: Instant Atmosphere on a Budget
Nothing changes a room faster than lighting. A single affordable smart lighting bulb costs around $12–$20 and gives you dimming, color changes, and schedules. Brands like Wyze and Philips Hue (the starter kit) offer excellent options under $100.
Set your bedroom lights to a warm orange tone an hour before bed. Or turn on the kitchen lights remotely when you’re carrying groceries. It’s small, but it feels futuristic every single day.

3. Video Doorbell Under $100? Yes, It Exists
Security used to be expensive. Not anymore. The Wyze Video Doorbell Pro costs around $55 and gives you 2K resolution, two-way audio, and motion alerts—no subscription required for basic clips. It’s one of the best entry-level smart home tech investments you can make.
Installation takes about 20 minutes if you already have doorbell wires. If you don’t, the battery version works just as well. Knowing who’s at the door from your phone is peace of mind you can’t put a price on.

4. Smart Thermostat: Save Money While You Sleep
A smart thermostat is the upgrade that pays for itself. The Google Nest Thermostat (not the Learning model) often sells for around $80–$100. It learns your schedule and adjusts the temperature when you’re away, cutting heating and cooling costs by up to 15%.
Installation is straightforward if you have a common C-wire, but there are adapters for older systems. I’ve seen friends reduce their monthly bills by $20 just by setting a away mode. That’s $240 back in your pocket per year.
| Device | Approx. Price | Best For |
|---|---|---|
| Smart Plug (Kasa) | $15–$20 | Automating lamps and small appliances |
| Smart Bulb (Wyze) | $12–$20 | Mood lighting and scheduling |
| Video Doorbell (Wyze Pro) | $55 | Front-door security and package alerts |
| Smart Thermostat (Nest) | $80–$100 | Energy savings and comfort control |
5. Smart Water Leak Detector: A $30 Insurance Policy
Water damage is one of the most expensive home repairs. A smart water leak detector from brands like Moen or Govee costs $25–$40 and sends an alert to your phone the second it senses moisture. Stick one under your sink, near the water heater, or behind the washing machine.
I placed one under my bathroom vanity after a small leak ruined the flooring. It gave me peace of mind without calling a plumber. For more ideas on preventing water damage during renovations, browse our bathroom renovation guides.
6. Smart Switch: The Permanent Upgrade
If you’re comfortable with basic electrical work—or you have a neutral wire—smart light switches are a game-changer. A single switch (like the TP-Link Kasa) costs about $20–$25 and gives you smart control from the wall, voice, and app.
Unlike bulbs, switches work with any standard light fixture. You can also create multi-way circuits if you have multiple switches for one light. It’s a cleaner, more permanent solution than swapping bulbs.

7. Smart Lock: Keyless Convenience Starts at $60
Imagine never fumbling for keys again. Smart locks like the Wyze Lock Bolt or August Wi-Fi Smart Lock cost around $60–$90. You can unlock the door with a code, your phone, or voice—and let guests in remotely.
Installation takes about 30 minutes and uses your existing deadbolt. No drilling needed. I use one on my back door for when the dog walker arrives. It logs every entry, so I know exactly who came and when.
FAQ: Affordable Smart Home Upgrades Under $100
Can I really build a smart home on a budget?
Absolutely. Start with one or two devices—like a smart plug and a bulb—and expand as you go. Many systems work without a hub, so you don’t need expensive infrastructure.
Do these devices work without Wi-Fi?
Most require Wi-Fi for app control and automation. A few, like some Zigbee devices, work locally. But for under $100, Wi-Fi-based devices are the most practical.
Will smart home upgrades save me money on utilities?
Yes, especially smart thermostats and plugs that schedule power-hungry devices. A smart thermostat can save 10–15% on heating and cooling costs annually.
Are these upgrades easy to install for a renter?
Most are plug-and-play. Smart plugs, bulbs, and leak detectors require zero modification. Switches and locks may need minor tools but are reversible.
Which brand is best for budget smart home devices?
Wyze, Kasa (TP-Link), and Govee offer excellent reliability under $50. They support Alexa and Google Assistant without costly hubs.
Can I control multiple devices from one app?
Yes. Alexa, Google Home, and Apple Home apps let you group devices by room or routine. You can say “Good night” and turn off all lights and lock the door.
Do I need a subscription for these devices?
Most do not require a subscription for basic features. For cloud recording on doorbells or cameras, there’s often an optional paid plan, but local storage is typically free.
How long do smart home devices last?
Expect 2–5 years for bulbs and sensors, and 5+ years for switches, locks, and thermostats. They’re surprisingly durable for the price.
Conclusion
Building a smarter home doesn’t require a massive budget. With these affordable smart home upgrades under $100, you can start small and scale up over time. Whether it’s a $15 plug that automates your morning coffee or an $80 thermostat that slashes your energy bill, every upgrade adds real value.
