PiHome DIY Kit

Complete DIY home automation kit — no enclosure, just DIN rail modules and sensors.
Raspberry Pi 5, Arduino Mega, sensors, and pre-configured software. Wire it yourself, exactly the way you want.

Connect. Power on. Automate.

PiHome DIY Kit includes all low-voltage components and a pre-configured software environment so you can start controlling lighting, heating, blinds, and socket circuits in your home right away. The distribution board enclosure and mains section are your responsibility — with the help of your electrician.

Choose your software — both are pre-installed and pre-configured

When placing your order, leave a comment with your preferred software for the Raspberry Pi. It will arrive pre-configured according to the PiHome model house.

How it works

• PiHome (Raspberry Pi 5) is the brain — it runs Home Assistant or OpenHAB and handles automation and the user interface.
• Arduino Mega boards read push buttons, PIR sensors, and room temperatures; they switch the relay modules. Think of them as a home PLC.
• Relay modules send a switching signal to the installation relays in your main electrical panel — safely controlling lights, blinds, sockets, or heating circuits.
• Control everything from your phone, tablet, or PC via a web interface — no cloud subscription required.

What else you'll need

These items are not included in the kit — source them yourself or with your electrician:

• Distribution board enclosure — you mount the kit into your own enclosure
• Mains section of the panel — circuit breakers and one installation relay per controlled circuit (lighting, blinds, heating zone); to be installed by a certified electrician
• Star-topology cabling — each controlled circuit has its own cable running back to the panel
• Wall push buttons (230 V, any manufacturer of your choice) connected via UTP/FTP cable (Cat5e or higher) — see the wiring diagram.
• Optional wireless extensions — Zigbee, Z-Wave, Modbus adapter, etc.

Quick start

Which components do we use and where do they come from

The heart of the system is the Raspberry Pi 5 microcomputer, made in the UK and fully certified for industrial use. The Arduino Mega boards serve as a home PLC — manufactured by an Italian company, always original, never clones. Power supplies are from Taiwanese manufacturer MeanWell, and the network switch from American brand Netgear. Krone terminals and relay modules are of Chinese origin but carry a European declaration of conformity. We prefer European manufacturers; all other components are used only where no alternative exists.

Compatibility and extensions

• Works with a wide range of brands and protocols via Home Assistant or OpenHAB add-ons
• Wireless extension: we recommend Shelly devices via MQTT or native integration
• USB adapters for Zigbee, Z-Wave, Modbus, and more can be added at any time
• Via CasaOS, install n8n, evcc, NodeRed, and hundreds of other applications with a single click

FAQ

Who is PiHome DIY Kit suitable for?

For technology enthusiasts and DIYers who want to build their own smart home — exactly to their own needs — without depending on closed commercial systems or paying licence fees. You don't need to be a programmer: it's enough to be technically minded, comfortable wiring a light switch, and able to crimp a UTP cable. For any questions, AI tools are a great help today, or you can always reach out to us directly.

What is the difference compared to PiHome Pro?

PiHome Pro is a fully assembled, wired, and tested Hager distribution board — just place it next to your main panel and connect it. The DIY Kit contains the same components without the enclosure: mounting, wiring, and configuration are up to you. You save on the assembly cost and gain full control over the layout.

Can I choose between Home Assistant and OpenHAB?

Yes. When ordering, select your preferred software — the Raspberry Pi will arrive pre-installed and pre-configured according to the PiHome model house. Both platforms are open-source with no licence fees. You can then adapt the entities to match your actual home layout.

Do I need a specialist electrician?

No. The mains section — circuit breakers and installation relays — can be connected by any certified electrician. A complete wiring diagram is included with every kit.

Does the kit meet GDPR requirements?

Yes. Data stays physically with you — nothing is sent to third-party servers unless you configure it yourself. Remote access is handled via VPN (WireGuard or Tailscale).

What if my Raspberry Pi or Arduino breaks?

Both platforms are widely available — you can buy them at any electronics retailer. The default OpenHAB or Home Assistant configuration and Arduino sketches are included with the kit; recovery takes minutes. Back everything up using the pre-installed Kopia application. We recommend keeping a spare Raspberry Pi as an offline backup — although we have never needed to use one ourselves or at any customer site so far.

Warranty and terms

• 24-month statutory warranty on all hardware
• Return of undamaged and unused components within 30 days of receipt, no reason required; full refund excluding shipping costs
• Warranty covers software functionality at the time of initial setup; regular system backups via Kopia are recommended
