Six months ago, I was staring at five different apps just to turn off my lights, check who was at the door, and see if I’d left the heating on. Six months ago, I decided there had to be a better way.
I spent €45 and a Saturday afternoon building a smart home dashboard that puts everything in one place. No subscriptions. No cloud dependencies. Just a simple screen on the wall that gives me control over my entire home.
Here’s exactly how I did it—and how you can too.

🛒 The Hardware: What You Actually Need
Before we dive in, let’s talk hardware. The beauty of this project is that you probably already have most of what you need.
Minimum Required Components
| Component | My Choice | Cost | Notes |
|---|---|---|---|
| Single-board computer | Raspberry Pi 3 or 4 | €0-€75 | Use an old one or buy used |
| Display | 8″ HDMI touchscreen | €30-€50 | Used/refurbished works great |
| Storage | 32GB+ SD card or SSD | €10-€30 | SSD recommended for databases |
| Power | Official Raspberry Pi power supply | €8-€12 | Don’t cheap out on power |
| Case/Stand | 3D printed or basic case | €0-€15 | A picture frame works too |
| Total | €45-€150 |
What I Used (Reused, Actually)
I had a Raspberry Pi 3 sitting in a drawer from an old project. The display was a refurbished 8″ touchscreen I found on eBay for €35. The total out-of-pocket cost? €45. Everything else I already had.
Hardware Recommendations by Budget
Budget Build (Under €50): Use a Raspberry Pi 3 you already own. Find a used 7-8″ touchscreen on eBay or Facebook Marketplace for €25-40. Use any SD card you have lying around (16GB minimum).
Recommended Build (€80-100): Raspberry Pi 4 with 4GB RAM (€55). New 8″ touchscreen (€45). 32GB SD card (€12). This gives you headroom for future expansion.
Premium Build (€150+): Raspberry Pi 4 8GB. 10″ display. Add an external SSD for all your media and database storage. Consider a PoE (Power over Ethernet) setup for cleaner wiring.
Hardware to Avoid
- Cheap no-name SD cards: They’ll corrupt. Spend €10 on a Samsung or SanDisk.
- Generic power supplies: Unstable power causes random crashes. Use official power supplies.
- Very small displays (under 7″): You can’t fit enough information. 8″ is the sweet spot.
- Old Raspberry Pi 2 or earlier: Too slow. Pi 3 is the minimum.
🏠 Why Home Assistant? The Decision Framework
I evaluated every major smart home platform. Here’s why I landed on Home Assistant—and why I think it’s the right choice for most people.
The Contenders
| Platform | Pros | Cons |
|---|---|---|
| Home Assistant | 100% local, 2,000+ integrations, open source | Steeper learning curve |
| HomeKit | Simple, secure, Apple integration | Limited device support, requires Apple devices |
| SmartThings | Easy setup, large ecosystem | Cloud-dependent, subscription fees |
| OpenHAB | Powerful, flexible | Complex UI, smaller community |
Why Home Assistant Won
1. Privacy First. Everything runs on your local network. Your data never touches the cloud. When your internet goes down, your smart home still works.
2. Device Agnostic. I have Philips Hue lights, a Nest thermostat, Ring doorbell, Spotify, and a handful of Tuya plugs. Home Assistant brings them all together seamlessly.
3. Open Source. No subscription. No vendor lock-in. If the company goes under, my smart home keeps working.
4. Active Development. With over 2,000 integrations and monthly updates, new device support arrives constantly.
5. Community. The Home Assistant community is incredible. Every question I’ve ever had has been answered in the forums or Discord.
When Home Assistant Might Not Be Right
- You want something that “just works” without any technical knowledge
- You’re fully committed to Apple HomeKit and only use HomeKit-compatible devices
- You have zero interest in learning or tweaking
📦 Step-by-Step Installation: Two Methods
You have two main paths to get Home Assistant running. I’ll walk you through both.
Method 1: Home Assistant Operating System (Recommended for Beginners)
This is the easiest way. It comes as a complete operating system optimized for Home Assistant.
What You Need
- Raspberry Pi 4 (or Pi 3 with 1GB+ RAM)
- 32GB+ SD card (high quality)
- SD card reader
- Computer for flashing
Step 1: Download the Imager
Go to home-assistant.io and download the Home Assistant Operating System imager for your computer type.
Step 2: Flash the SD Card
- Insert your SD card into your computer
- Open the Home Assistant imager
- Select your Raspberry Pi model
- Select “Home Assistant Operating System”
- Choose your SD card
- Click “Write” and wait for it to complete
Step 3: First Boot
- Insert the SD card into your Pi
- Connect the Pi to your network (Ethernet recommended for setup)
- Connect power and turn it on
- Wait 10-20 minutes for initial setup (it downloads updates)
- Navigate to homeassistant.local:8123 in your browser
Step 4: Create Your Account
You’ll be prompted to create an admin account. Remember these credentials—they’re the keys to your smart home.
Step 5: Add Your First Devices
Home Assistant will auto-detect many devices on your network. For devices that don’t auto-detect, you’ll add them through Settings → Devices & Services.
Method 2: Docker on Raspberry Pi OS (For Advanced Users)
If you want more control or plan to run other services alongside Home Assistant, Docker is the way to go.
Step 1: Install Raspberry Pi OS
Use the Raspberry Pi Imager to install Raspberry Pi OS Lite (no desktop) or Desktop if you want a display attached.
Step 2: Install Docker
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo usermod -aG docker $USER
Step 3: Install Docker Compose
sudo apt-get update
sudo apt-get install docker-compose-plugin
Step 4: Create Docker Compose File
mkdir ~/home-assistant
cd ~/home-assistant
nano docker-compose.yml
Add this content:
version: '3.8'
services:
homeassistant:
container_name: homeassistant
image: "homeassistant/home-assistant:stable"
ports:
- "8123:8123"
volumes:
- ~/home-assistant/config:/config
- /etc/localtime:/etc/localtime:ro
restart: unless-stopped
privileged: true
network_mode: host
Step 5: Start Home Assistant
docker compose up -d
Navigate to homeassistant.local:8123 and set up your account.
🎨 Dashboard Design: Principles That Work
I’ve been running my dashboard for six months now. Here’s what I’ve learned about making it actually useful.
The Three-Zone Layout
My dashboard has three horizontal zones, and I’ve found this works better than anything else I’ve tried.
Zone 1: Status Bar (Top 15%)
This zone shows information you need at a glance but rarely interact with:
- Current time and date
- Weather (current temp and forecast)
- System status (any devices offline?)
- Security status (doors locked, alarm armed)
Zone 2: Scenes & Modes (Middle 50%)
This is your command center. Large, easy-to-tap buttons for the states you use most:
- Morning: Lights on, heating up, coffee maker start
- Away: All lights off, heating down, doors locked
- Movie Night: Living room lights dim, TV input switch
- Guest Mode: Simplified controls for visitors
- Goodnight: All lights off, doors locked, alarm armed
Zone 3: Quick Controls (Bottom 35%)
Single-tap controls for the things you adjust multiple times a day:
- Individual room lights (on/off/dim)
- Thermostat controls
- Music playback
- Frequently used scenes
Design Best Practices
Size for Touch. If you’re mounting this on a wall, every button needs to be at least 60×60 pixels. Make your most-used buttons largest.
Color Code Consistently. I use green for “on” states, gray for “off,” and amber for warnings. Users learn the system quickly.
Limit Choices. The paradox of choice applies here too. I initially had 12 buttons. Now I have 6, and the dashboard is far more useful.
Hide Complexity. Advanced controls and settings are accessed through a different view. Your dashboard should be simple—dig deeper when you need to.
My Actual Dashboard Configuration
Here’s my Lovelace YAML for the main view (simplified):

💡 Pro Tips: Six Months of Daily Use
These are the things I wish I’d known when I started.
Do: Use a Static IP Address
Your router assigns IPs dynamically, which means your dashboard’s IP could change. When that happens, everything breaks. Set a DHCP reservation in your router for your Pi’s MAC address.
How to find your Pi’s MAC address:
ip link show eth0 | grep link/ether
Then log into your router and add a reservation for that MAC address.
Do: Set Up Backups Early
I learned this the hard way. Home Assistant has a built-in backup system—use it.
Automate daily backups to a different device:
# Add to your configuration.yaml
backup:
folder: backups
keep_days: 30
location: /share/backup
Then set up a cron job to copy those backups to another device or cloud storage.
Do: Start Simple
I added 15 integrations on day one. It was overwhelming. Start with 2-3 essential devices. Get them working perfectly. Then add more.
Don’t: Automate Everything at Once
Automations are powerful but dangerous when overused. Every automation needs testing. Add them one at a time and verify they work as expected.
Don’t: Skip the YAML Basics
Home Assistant has a visual editor, but you’ll eventually need to edit YAML. Learn the basics: how to restart, where files are located, how to check for errors.
Essential YAML locations:
Don’t: Forget to Secure Remote Access
Home Assistant includes remote access through Nabu Casa (cloud) or you can set up your own VPN. Never expose Home Assistant directly to the internet without authentication.
Recommended: Use Home Assistant Cloud
For €5/month, Nabu Casa gives you secure remote access, voice assistant integration, and supports the project. Worth every euro.
Use Entity Naming Conventions
Name your entities consistently from the start:
light.living_room_main
light.living_room_lamp
switch.office_plug
switch.coffee_machine
Trust me—naming them “light 1” and “plug A” becomes unmanageable quickly.
Enable YAML Mode for Advanced Users
Go to your user profile and enable “Advanced Mode.” This unlocks hidden options and gives you more control over your configuration.
🚀 Five Projects to Expand Your Dashboard
Once your basic dashboard is running, here are five projects to take it to the next level.
Project 1: Presence Detection
Know who’s home and trigger automations accordingly.
How it works: Home Assistant tracks which devices are on your network. When your phone connects to WiFi, it knows you’re home.
Automation ideas:
Project 2: Doorbell Notifications with Camera Snap
When someone rings your doorbell, get a notification with their photo.
How it works: Ring integration triggers an automation that saves the camera snapshot and sends it to your phone.
Automation YAML:
- alias: Doorbell Notification
trigger:
platform: state
entity_id: binary_sensor.front_doorbell
to: 'on'
action:
- service: camera.snapshot
entity_id: camera.front_door
data:
filename: /config/www/doorbell_snap.jpg
- service: notify.mobile_app
data:
title: Someone's at the door
message: Pressed the doorbell
data:
image: /local/doorbell_snap.jpg
Project 3: Morning Routine Dashboard
One button that starts your entire morning routine.
What it triggers:
Create it as a script:
script:
morning_routine:
alias: Morning Routine
sequence:
- service: light.turn_on
entity_id: light.bedroom
data:
brightness_pct: 30
kelvin: 3000
- delay: "00:05:00"
- service: light.turn_on
entity_id: light.bedroom
data:
brightness_pct: 80
- service: switch.turn_on
entity_id: switch.coffee_maker
- service: climate.set_temperature
entity_id: climate.living_room
data:
temperature: 22
hvac_mode: heat
Project 4: Vacation Mode
When you’re away for extended periods, make your home look occupied.
What it does:
Project 5: Energy Monitoring Dashboard
Track your energy consumption and find ways to save.
Hardware: Shelly Pro 4PM or similar energy-monitoring smart switch.
Dashboard cards:

❓ Frequently Asked Questions
Can I use this without a Raspberry Pi?
Absolutely. Home Assistant runs on:
How much electricity does this use?
Very little. A Raspberry Pi 4 with display draws about 5-10 watts. At €0.25/kWh, that’s roughly €1-2 per year. Negligible.
What if my internet goes out?
Everything continues to work locally. Your smart home doesn’t need the internet. You just won’t be able to access it remotely until internet is restored.
Can multiple people control it?
Yes. Each user can have their own login and preferences. The dashboard can be different for different users.
How secure is this?
Very, if configured properly. Home Assistant uses bcrypt for passwords, supports 2FA, and all data stays local. Just don’t expose it directly to the internet without proper authentication.
What’s the difference between Home Assistant and Home Assistant Operating System?
Home Assistant Operating System (HAOS) is a complete, optimized Linux distribution that only runs Home Assistant. It’s the easiest to set up and most reliable. Home Assistant Supervised (formerly Hass.io) runs on top of an existing Linux installation and allows running other software alongside. Home Assistant Container runs in Docker only. Home Assistant Core is the Python application itself.
Do I need coding knowledge?
Basic familiarity helps, but isn’t required. You can do 80% of what you want through the visual editor. The remaining 20% (advanced automations, custom components) requires YAML editing.
Can I take this with me when I move?
Yes. Just take the SD card (or configuration folder), set up on new network, and you’re done. Your automations and devices come with you.
What happens if the SD card corrupts?
If you have backups, you restore and are back online in 15 minutes. This is why I emphasize backups repeatedly.
Is there a mobile app?
Yes, Home Assistant has excellent iOS and Android apps. They support notifications, device tracking, and full dashboard access.
🎯 Summary: Your Action Plan
Here’s everything we covered, distilled into actionable steps.
Week 1: Build the Foundation
Week 2: Expand and Refine
Month 2: Advanced Projects
Key Takeaways
I built my dashboard on a Saturday afternoon for €45. Six months later, I can’t imagine my home without it. When I walk in the door and tap “Evening,” the lights warm, the music starts, and the thermostat adjusts—all without pulling out my phone.
That’s the promise of a truly smart home: technology that disappears into the background, leaving you with a home that just works.
Start with what you have. Expand as you learn. And remember: the goal isn’t to use every feature—it’s to make your daily life a little easier.
