Top-Rated Budget Smart Plugs (Under $30)
Smart plugs let you turn any outlet into a programmable outlet on a Wi-Fi network. Our top picks are reliable, don’t need a hub, and cost around $10–$30. For example, TP-Link’s Kasa Smart Plug Mini (EP25) is widely recommended. It’s a compact Wi-Fi plug ($17–$18 each, ~$30 for a 2-pack) that works with Alexa and Google Home. Wyze also makes a popular plug (2-pack for $25) that offers scheduling and away modes with a free app. Even cheaper clones like Aoycocr Smart Plug ($10) or multi-packs like GHome Smart Mini Plug (4-pack under $27) give great value.
- TP-Link Kasa Smart Plug Mini – ~$18 each (2-pack ~$30). Compact design with app scheduling. Works via Wi-Fi (no hub) and has no recurring fees.
- Wyze Smart Plug – 2-pack for ~$25. Supports Alexa/Google, plus handy features like “vacation mode” scheduling. (No hub required; Wyze app is free.)
- Aoycocr Smart Plug – ~$9 each. A super-cheap option (requires the Smart Life app) that still supports voice control. Good for automating multiple devices on a budget.
- GHome (Gosund/Teckin) Smart Plug – 4-pack for ~$27 ($6.75 each) with voice and app control. Great if you need many plugs.
Setting one up is easy: plug it in, open the manufacturer’s app, and connect to your home Wi-Fi (often via Bluetooth pairing). The app lets you give each plug a name, set schedules or timers, and group them into “scenes.” In Engadget’s testing, “adding a smart plug to your home is relatively simple” – you connect in the app, then integrate it into your ecosystem. Once added, you can trigger routines or voice commands to turn lamps, fans, or coffee makers on/off on a schedule or remote command.

Affordable Smart Lights (Under $30)
Upgrading bulbs to smart LEDs is one of the fastest DIY “smart home upgrades.” You can swap regular bulbs for smart bulbs that work over Wi-Fi. Budget picks include: the Wyze Bulb ($7–$8) – a simple white Wi-Fi bulb – and color bulbs from TP-Link Tapo or Sengled. For instance, Wyze’s plain-white smart bulb costs only $7.99 apiece and still offers app control, Alexa/Google support, and automations. It even works without any hub or extra hardware.

- Wyze Smart Bulb (White, $7.99) – Extremely cheap and Wi-Fi enabled, so no hub is needed. Great for beginners, though it only does dimmable white light (no colors).
- TP-Link Tapo L530E (Color, ~$16) – Full-color Wi-Fi bulb. Supports 16M colors, Alexa/Google, and app scenes. (U.S. model: TP-Link Kasa KL125, similar price.)
- IKEA Trådfri Bulb (White or Color, ~$8+) – Very low-cost bulbs. They work best with IKEA’s own gateway ($25) for app/voice control, though you can also pair them to some Zigbee hubs.
- Sengled Smart LED (Color, ~$12) – Wi-Fi color bulb with no hub needed. A good balance of price and features (works with major assistants).
- Nanoleaf Essentials (Color, ~$20) – Unique geometric bulb shape with HomeKit/Thread support, bright output.
As with plugs, setup is straightforward: screw in the bulb, power it on, and use the vendor’s app to detect and configure it. You can usually set up brightness, colors (if supported), and schedules via the app. Many bulbs also let you create lighting “routines” or sync them together for smooth transitions.

Budget Smart Sensors (Doors, Windows, Motion)
Smart sensors (door/window contact sensors, motion sensors, etc.) add automation and security cues to your system. They tend to cost a bit more, but you can find many under $30. A top pick is the Aqara Door/Window Sensor (uses Zigbee) – it’s tiny, reliable, and usually about $15–$18 each (often on sale for ~$15). Because it runs on Zigbee, it requires a hub (like a SmartThings Hub, Aqara hub, or Home Assistant’s Zigbee stick), but it offers very long battery life.
For example, one review notes the Aqara sensor “is normally priced at $18 and can frequently be found on sale for a few dollars less”. Its tiny size (only 1.5″ tall) makes it easy to hide on a door frame. It can integrate with many platforms (Home Assistant, SmartThings, Hubitat, etc.) thanks to Zigbee compatibility.
If you want no-hub Wi-Fi sensors, options include the Sonoff DW2-WiFi contact sensor (~$12) or Shelly Door/Window. These connect directly to your network but may need more frequent battery changes. (Note: many budget Wi-Fi sensors have shorter life than Zigbee ones, so weigh convenience vs. longevity.)
Other sensor ideas: motion sensors (e.g. Aqara or Wyze motion ~ $10–15), multi-sensors (detect motion+temperature), and even inexpensive Siren alarms (<$20).

Getting Started: Setup & Automation Basics
With your new devices in hand, setup is mostly app-driven. As Engadget explains, you typically “use the manufacturer’s app to initially connect” the device to Wi-Fi, then add it to your smart home platform. For a smart plug, this might mean plugging it in, opening the Kasa/Wyze app, and following the on-screen pairing. Once added, you can name the device, set schedules, or include it in routines. For example, use the app to turn lights on at sunset or have a plug switch off the coffee maker at bedtime.
Smart bulbs pair similarly: screw them into a socket, power them up, then use the bulb’s app to find the new light. You can then assign it a room name and control it via voice or app. Sensors (contact or motion) often pair by first pressing a button (to enter pairing mode) and then selecting them in the app or hub interface.
Once added, all these devices can be automated. Many vendors’ apps let you create simple schedules or “if-this-then-that” rules. For example, set IF motion is detected THEN turn on a hallway light. For cross-brand automation, you’ll use a smart hub or platform (see next section).
Automation Platforms: IFTTT, SmartThings, Home Assistant
To tie everything together (especially if your devices are from different brands), you’ll likely use an automation platform. The big ones include Samsung SmartThings (cloud-based with Zigbee/Z-Wave hub options), IFTTT (web-based triggers/actions), and Home Assistant (free, local, DIY software).
- IFTTT (If This Then That) is free and supports thousands of triggers. You can link apps and devices (e.g. “If Weather Underground says rain, turn on outdoor lights”). It works with many smart plugs, bulbs, and sensors via their IFTTT channels. (Note: IFTTT’s free tier has limits, but it’s great for beginners.)
- SmartThings (Samsung) can pair Wi-Fi, Zigbee, and Z-Wave devices under one app. Use it to create routines like “Goodnight” (turn off all lights and lock doors) or “Movie Mode” (dim lights when TV turns on). Most major brands explicitly list SmartThings compatibility, and you add devices through the SmartThings app.
- Home Assistant is an open-source hub you run on a Raspberry Pi or local server. It integrates literally thousands of devices and services. You can add your Kasa/Wyze plugs, Zigbee sensors (with a USB stick), and more. Home Assistant excels at local, privacy-focused automation, and lets you create complex automations (time-based, sensor-based, even webhooks) without relying on a cloud.
As one review notes, you’re not limited to one ecosystem – “you can turn to open-source software like Home Assistant or go with the larger functionality of IFTTT”. In practice, use voice assistants (Alexa, Google) for simple commands, and use SmartThings or Home Assistant for inter-device rules. For instance, set Home Assistant to “turn off all lights” when your phone’s GPS indicates you’ve left home. Or use IFTTT to “turn on a smart plug when an RSS feed updates.” The possibilities are endless.
Automating Old Appliances: IR Blasters & Smart Relays
Don’t toss those old devices yet – you can retrofit them to be smart! One trick is an IR blaster (infrared emitter) that mimics a remote control. For example, the Broadlink RM4 Mini (around $20–$25) learns IR commands from your old remotes. Once set up, it can “send out signals to control a variety of older home devices such as your TV or ceiling fan”. In practice, you put your TV remote in learning mode with the RM4, so the blaster can power the TV on/off, etc. Then use the Broadlink app or Alexa/Google to trigger it. Tom’s Guide notes that with an IR blaster, you make “the devices you already own visible to your smart [system]” and can “incorporate them into automations”. For instance, you could automate your fireplace (IR remote) to turn on if a temperature sensor reads cold, or wake up to music by powering on an IR-controlled speaker.

Another approach is a smart relay/switch module. These small modules (like Sonoff Basic or Shelly 1) go behind a wall switch or inside an appliance’s plug. The Sonoff Basic is a famous example – essentially a Wi-Fi relay for about $5. You wire it in parallel with a light switch, so it can cut power to the light on demand. The Shelly 1 (about $8) is similar but smaller. Reviews note the Shelly 1 “directly competes with everyone’s favorite $5 smart switch” (the Sonoff Basic). Using these, you can control ceiling fans, lamps, or even garage doors from your phone or automations, without replacing the entire fixture. (Important: only attempt wiring if you are comfortable with home electrical or get help!)
In short, any device with a remote or switch can become smart with these tricks. Use an IR blaster (Broadlink, Logitech Harmony, or even an old phone with IR) for infrared remotes; use a smart relay module (Sonoff, Shelly, or Kasa in-wall switches) for direct line-power control.
Conclusion
In summary, affordable smart home upgrades are within reach. Start with cheap smart plugs ($10–$25), bulbs ($8–$20), and sensors ($15–$30) to automate lights, appliances, and security. Use free platforms like IFTTT or Home Assistant to tie everything together. And don’t overlook creative hacks: an IR blaster or a $5 relay can make even “dumb” devices smart. With some DIY spirit and a few budget gadgets, you’ll enjoy the convenience of a smart home without a big investment. Happy automating!
