How to Build a DIY Smart Home Automation System on a Budget

Introduction

Building your own smart home doesn't have to cost a fortune. With careful planning and budget-friendly components, I was able to put together an automated home system that provides convenience and security without breaking the bank. Here is my guide to building a DIY smart home automation system on a budget.

Determine Needs and Priorities

The first step is deciding which smart devices and functions are most important in my home. For me, these priorities were:

I recommend making a list of features you want and ranking them by importance. This helps focus your efforts and budget on the things that matter most.

Choose a Hub or Controller

The center of any smart home is the hub or controller that everything connects to. This allows you to control and automate devices from a central app or via voice control.

I opted for the Samsung SmartThings Hub because it offers good integration across brands at an affordable price point (around $70). Other budget options include the Wink Hub 2 and Hubitat Elevation which cost $50-90.

Make sure any hub you choose works with the wireless protocols your devices use - WiFi, Zigbee, Z-Wave, etc.

Select Compatible Devices

With the hub selected, I researched smart devices that were budget-friendly and compatible.

Lighting Control

For lighting, I went with TP-Link Kasa smart bulbs which connect directly to WiFi without a separate bridge or adapter. A 2-pack of multicolor bulbs costs around $20. Controlling them is as simple as screwing them into any lamp or fixture.

Security Cameras

Wyze cameras only cost $25-35 each but have good 1080p video and easy app access. I put one indoor to monitor the entryway and one outdoor covering the backyard. Storage requires an SD card.

Smart Thermostat

The Ecobee Lite smart thermostat has all the main features for around $169. It's easy to install and integrates nicely with SmartThings. Setting schedules has helped manage my energy costs.

Smart Locks

I went with the August Smart Lock Pro which replaces your existing deadbolt. It auto-locks, provides remote access via the app, and was under $200.

Other Options

If budget allows, consider smart switches, sensors, smoke detectors, water leak sensors, smart outlets, and smart appliances. Prioritize what's most useful for your situation.

Installation and Configuration

With all the components purchased, it was time for installation and setup. Most devices were easy DIY projects requiring no special tools.

The SmartThings hub, Wyze cameras, August smart lock, and Ecobee thermostat all connected to WiFi and were controlled primarily through their own mobile apps.

For the Kasa smart bulbs, I simply screwed them into light sockets and connected them to the Kasa app. I linked the Kasa account to SmartThings so I could also control the bulbs through the SmartThings app.

After connecting each device, I used the SmartThings app to configure automation rules like turning lights on at sunset and off at bedtime. Activity alerts from the cameras trigger porch lights to come on automatically as well.

Conclusion

Creating my own DIY smart home system was incredibly rewarding. Despite having limited DIY experience, I was able to put together a feature-rich automated home through careful planning and by sticking to a strict budget.

The total cost was under $1000 which is quite affordable compared to professionally installed systems or those using high-end gear. My home is now easier to manage, more secure, and saves energy with minimal ongoing costs.

With the right combination of an affordable hub, compatible devices, and a little elbow grease, you can build an impressive smart home automation system on a budget too! Let me know if you have any other questions.
