Building a smart home doesn’t have to mean emptying your wallet or settling for low-quality gadgets. The market today offers a wide variety of affordable smart home devices that balance cost and performance, ensuring you get great value without sacrificing functionality. Whether you’re just starting your smart home journey or expanding an existing setup, these budget-friendly picks cover everything from lighting to security, automation, and environmental monitoring.
Here’s a detailed look at some of the best inexpensive smart home devices you can buy right now—tested and trusted to perform well without the premium price tag.
Smart Light Bulbs: Affordable and Functional
Smart bulbs are the cornerstone of any smart home setup. You don’t need to spend a fortune to get reliable, bright, and colorful lighting.
-
Casa Smart Bulb: Priced around $13, this 1000-lumen bulb offers decent brightness and colors. While it’s not Matter certified (a standard for future-proof smart home compatibility) and has a CRI (color rendering index) of 88, it works with most popular smart home systems. Perfect for lamps you want to upgrade without overspending.
-
Topo Matter Certified Bulb: This 1100-lumen bulb supports Matter for robust compatibility but suffers from poor connectivity issues. It’s not recommended despite the attractive price and brightness.
-
Lincoln Matter Bulb: A surprising standout, Lincoln offers Matter-certified bulbs in two sizes (800 and 1600 lumens), with a CRI over 90 for better color accuracy. Though colors aren’t as vibrant as Casa, the white light quality is solid, and connectivity is excellent. For price, compatibility, and reliability, this is a top pick.
Takeaway: For a mix of affordability, brightness, and future-proof tech, Lincoln’s Matter bulbs are hard to beat.
Light Strips: Stylish and Versatile
Light strips can be both functional and stylish without being tacky or overwhelming.
-
Whiz Light Strips ($33): Featuring warm and cool white LEDs that blend nicely with Philips Hue systems (both brands share a parent company). These strips offer bright whites but less vibrant RGB colors. They use Wi-Fi and integrate well with most ecosystems.
-
Accara T1 Zigbee Strips ($45): Brighter RGB colors and Zigbee connectivity allow direct Home Assistant integration with a Zigbee dongle. However, full-color effects require using the Accara Zigbee hub. Warm and cool whites are less bright than Whiz.
Takeaway: For primarily white-light use in living spaces, Whiz offers better brightness and value. For RGB enthusiasts with Zigbee setups, Accara is worth the extra investment.
Video Doorbells: Security Without Fees
Video doorbells are among the most popular smart home devices, but many cheap models come with hidden monthly fees.
-
Real Link Wi-Fi Doorbell ($110): A standout budget option with no monthly fees, 24/7 recording to an SD card or to a dedicated NVR (network video recorder). It supports HDR, providing clear footage even in challenging lighting where competitors like UI E340 blow out highlights.
-
UI E340 Doorbell ($150): Also no fees and decent performance but pricier and lacking the affordability and recording flexibility of Real Link.
Takeaway: Real Link offers professional-grade features at a fraction of the price, making it the best budget pick for video doorbells.
Smart Door Locks: Convenience and Security
Smart locks need to balance ease of use with security. Fingerprint readers are among the fastest and most reliable unlocking methods.
-
Yuthi E31 ($150): Lightweight with a rechargeable battery, supports Matter for basic lock/unlock via Home Assistant but requires the Yuthi app for advanced features like fingerprint setup. Its light build raises durability concerns.
-
Accara U00 ($142): Heavier and more rugged, this lock pairs directly with Apple HomeKit and supports Home Key for unlocking with iPhone/Apple Watch. The fingerprint sensor works well even with sweaty hands—a plus in hot climates. Requires an Accara hub for Matter compatibility and Home Assistant integration.
Takeaway: The Accara U00 offers superior build quality and usability, making it the better overall value despite the need for a hub.
Smart Light Switches: Simple and Effective
When it comes to budget smart switches, reliability and compatibility are key.
- Casa Dimmer and On/Off Switch (~$20): These Matter-certified switches connect seamlessly with major smart home platforms and Home Assistant. They offer straightforward functionality without frills, defining the sweet spot between price and performance.
Indoor Cameras: Affordable Monitoring
For indoor security or baby monitoring, affordable cameras with no fees and good integration are essential.
- Topo C120 (~$25): Records 24/7 to an SD card, offers multiple detection types (including baby crying), and integrates directly with Home Assistant for live streaming—features rarely found at this price point.
Outdoor Cameras: Reliable and Smart
Outdoor cameras need to be rugged, reliable, and integrate well with your smart home.
- Riolink RLC 810A (~$80): A hardwired 4K camera that supports 24/7 recording via a Riolink NVR, offers excellent reliability and smart home integration. Avoid solar/battery-powered models if you want solid Home Assistant compatibility.
Motion Sensors: Affordable Automation Essentials
Detecting motion is a fundamental automation trigger.
- Accara and Third Reality Motion Sensors (~$20): Both Zigbee devices with good performance. Third Reality’s use of AAA batteries (preferably rechargeable) offers convenience and longer life compared to Accara’s coin cell batteries. Third Reality also integrates well with Echo devices via Zigbee hubs.
Millimeter Wave Sensors: Presence Detection
These sensors detect presence based on micro-movements like breathing, going beyond simple motion detection.
-
Treatife Millimeter Wave Sensor ($30): Basic presence detection for Amazon or Google ecosystems.
-
Accara FP1E ($40): Zigbee-based, easy Home Assistant integration, shows distance of detected motion.
-
Apollo MSR2 ($40): Smaller, mounts on wall outlets, uses ESP Home for integration—ideal for Home Assistant users comfortable with custom setups.
Contact Sensors: Monitoring Doors and Windows
Reliable contact sensors help secure entry points.
- Third Reality vs. Accara: Similar to motion sensors, Third Reality uses larger AAA batteries and offers stronger magnets for better reliability. Accara is smaller but prone to occasional offline issues.
Water Leak Sensors: Inexpensive Protection
Water leaks can cause costly damage, so affordable sensors are invaluable.
-
IKEA Water Leak Sensor ($10): Extremely affordable, Zigbee-enabled, AAA battery-powered with a built-in siren. Works well with Home Assistant.
-
Third Reality Leak Sensor: Offers louder siren and more sensing options but at twice the price.
Smart Buttons: Simple Automation Triggers
Smart buttons are great for triggering scenes or automations.
-
Third Reality Smart Button: Zigbee, AAA battery-powered, available in multiple colors, supports multiple press types.
-
Philips Hue Switch ($22): Slightly pricier but optimized for lighting control with intuitive press types and magnetic mounting.
Vibration Sensors: Detecting Movement and Tampering
Useful for detecting vibrations on windows, doors, or valuables.
-
Third Reality Vibration Sensor ($20): Adjustable sensitivity, responsive, AAA battery-powered.
-
Accara Vibration Sensor ($17): Cheaper but less sensitive and uses coin cell batteries.
Smart Outlets: Power Monitoring on a Budget
Tracking energy usage helps optimize appliance efficiency.
-
Casa Wi-Fi Outlet: Matter-enabled, but energy monitoring only available through Casa’s own integration, not via Matter.
-
IKEA and Third Reality Zigbee Outlets ($12-$13): Both provide power and energy monitoring, benefit from Zigbee repeaters for extended range.
Garage Controllers: Reliable and Affordable
Smart garage door controllers add convenience and security to your home.
- Maros Garage Controller ($30-$50): Supports Amazon, Google, SmartThings, and HomeKit (higher-priced version). Includes a wired sensor (no batteries needed) for reliable operation, with free adapters for new garage door openers.
Thermostats: Budget with Quality
Smart thermostats save energy while keeping you comfortable.
-
Honeywell X2S (~$100): New Matter-certified option.
-
Ecobee Essential ($130): Slightly pricier but offers superior controls and local HomeKit integration. Missing a built-in motion sensor but compatible with Ecobee room sensors.
Air Quality Monitors: Breathing Easy
Monitoring air quality is increasingly important for health.
-
Apollo MSR2 with CO2 Sensor ($50): Adds CO2 detection to millimeter wave sensing—great for stuffy rooms.
-
IKEA Air Quality Sensor: Zigbee-enabled, monitors particulate matter and VOCs, ideal for kitchens or workshops.
