Pi 4 Home Assistant Hub Kit with Raspberry Pi 4 + Relay
Pi 4 Home Assistant Hub Kit – Take Control of Your Smart Home with Raspberry Pi 4
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your Raspberry Pi 4 into the brain of your smart home. This kit lets you build a fully functional Home Assistant hub that controls appliances via relays, senses temperature and humidity, and can be extended with Zigbee devices for whole-home automation. From automating fans and lights to creating intelligent routines that respond to environmental changes, every component is here to get your smart home up and running.
What You'll Build
A custom home automation controller running Home Assistant OS on the Raspberry Pi 4. You’ll wire dual relay modules to switch lights, fans, or other electrical loads from your smartphone, integrate the DHT22 sensor for environmental monitoring, and set up automation rules that respond to conditions or schedules. The result is a reliable, locally controlled smart home hub without dependence on cloud services.
What You'll Learn
- How to flash Home Assistant OS onto a Raspberry Pi 4 and configure it for local smart home control.
- Wiring 5V relay modules safely with flyback diodes to control AC appliances.
- Reading environmental data from a DHT22 sensor and incorporating it into automation logic.
- Designing automation rules and understanding Zigbee integration for smart home devices.

Who This Kit Is For
Ideal for CBSE Class 12 students building IoT-based home automation projects for board practicals, B.Tech ECE and EEE students exploring embedded smart home solutions, and participants in hackathons like Smart India Hackathon. It also fits ATL Tinkering Labs and engineering college labs at IIT, NIT, VIT, or BITS Pilani where smart home prototypes are demonstrated.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to access the AI build companion trained on this exact project, which offers step-by-step guidance. If you still need help, send a WhatsApp message to our support team for real-time assistance.
Can I control 230V appliances like lights and fans safely?
Yes, the kit includes 1N4007 flyback diodes to protect the relay circuits. However, working with mains voltage requires proper insulation and adult supervision. Follow the AI companion's safety instructions and consider using a qualified electrician for final AC connections.
Do I need to buy a Zigbee dongle separately?
The kit does not include a Zigbee dongle, but you can easily add one like the ConBee II or SONOFF Zigbee USB dongle. The AI companion includes guidance on integrating a dongle into Home Assistant for controlling Zigbee lights and sensors.
Is prior Python or programming knowledge required?
This kit uses Home Assistant OS, which relies on a visual automation editor and YAML configuration rather than hardcore programming. The AI companion walks you through the setup, so basic computer skills are enough to get started.
Pi 4 runs Home Assistant OS. GPIO relay control, Zigbee dongle support, automation rules for smart home.
