Starting a smart home doesn't require a huge budget. These five beginner-friendly picks under $100 cover hubs, smart lighting, and even outdoor irrigation — each a solid building block you can expand from.
Starting a smart home doesn't require a huge budget. For under $100, you can pick up a capable hub and speaker, add smart lighting, and even bring smart control to your yard. The key is choosing devices that act as building blocks — start with one, then expand as you go.
All five picks below are budget or mid-range priced, beginner-friendly with simple setup, and ecosystem-flexible via protocols like Matter, Zigbee, and Thread. Whether you're team Alexa, Apple Home, or just want a cheap way to automate your sprinklers, there's something here for you.

The Echo 4th Gen is the most feature-rich beginner hub you can get at this price. It has a built-in Zigbee hub, a Thread Border Router, and Matter support, which means it can control devices across different ecosystems without requiring extra bridges1. That's a lot of protocol support packed into one spherical speaker.
For most people starting from scratch, this is the easiest entry point into the Alexa ecosystem. Plug it in, connect to Wi-Fi, and start adding devices. The Zigbee radio means you can pair affordable sensors and bulbs directly, and the Thread/Matter support future-proofs your setup as more devices adopt those standards.
It's frequently discounted below its list price, making it a realistic sub-$100 purchase1.
If you're already invested in Apple's ecosystem, the HomePod mini is the natural choice. At $99, it serves as both a Matter controller and a Thread Border Router for Apple Home2. It's compact, sounds great for its size, and integrates deeply with HomeKit.
Setup is as simple as bringing your iPhone near it. From there, you can control HomeKit accessories, use Siri for voice commands, and build automations through the Home app. The Thread Border Router support means any Thread-compatible device you add later will benefit from a more reliable mesh network.
For Apple users, this is the hub that makes the most sense — and it stays within the $100 budget.
The Aqara Hub M1S is a compact Zigbee hub that punches above its weight class. It sits in the budget price band and includes a built-in security siren for HomeKit alerts3. Pair it with Aqara's affordable sensors — motion, door/window, water leak — and you've got the foundation of a low-cost home security system.
It supports HomeKit, so it works alongside Apple Home setups, and it also works with Alexa. The hub itself is small enough to plug into any outlet, and adding sensors is as simple as scanning a QR code in the Aqara app.
If your priority is security rather than music or voice control, this is the most cost-effective way to start.
Smart home isn't just about indoor gadgets. The Orbit B-hyve brings smart control to your yard with weather-based watering adjustments, easy DIY installation, and app-based control4. It replaces your existing sprinkler controller and connects to Wi-Fi, letting you manage zones and schedules from your phone.
The weather-based adjustment is the standout feature — it skips watering cycles when rain is forecast, which can save water and money over time. Installation is straightforward for most homes, and the app walks you through zone setup step by step.
For anyone curious about smart yard tech, this is the most accessible entry point under $100.
The Govee RGBIC is the easiest way to add ambient smart lighting without spending much. It features music sync, 99+ preset scenes, RGBIC technology (which allows multiple colors on a single strip), and simple USB power5. Just plug it in, connect to the Govee app, and you're set.
It works with Alexa and Google Assistant for voice control, and the app offers extensive customization — from static colors to dynamic scenes that react to music. The USB power means you don't need a dedicated outlet; you can power it from a TV USB port or any USB adapter.
For beginners who want a taste of smart lighting without committing to a full bulb replacement, this is the cheapest, simplest option.
Your ecosystem choice drives the decision more than anything else:
The beauty of starting with Matter and Thread-compatible devices is that they're increasingly interoperable. You don't have to commit to one ecosystem forever — pick what works today, and expand later.
