PiHome Pro - OpenHAB Edition

Complete home automation in an assembled low-voltage distribution board — sensors included.

PiHome Pro matches the configuration of the model house. The board is pre-wired, configured, and programmed with OpenHAB. Simply mount it next to your main electrical panel, have an electrician connect the RSA terminal outputs to the mains installation relays, and connect sensors and push buttons for lights and blinds via UTP cable.

Connect. Power on. Automate.

What you get

Hardware
PiHome Pro is a system integration of proven components — Raspberry Pi 5, Arduino Mega, original relay boards, certified MeanWell power supplies, and a Hager enclosure — assembled, configured, and tested. We act as a system integrator. Every component carries the certification (CE/UKCA) of its respective manufacturer.

Software
The heart of the system is OpenHAB running on a Raspberry Pi 5. Switching and data collection from rooms is handled by Arduino Mega boards acting as a home PLC — an open platform with long-term availability of spare parts and community support.

Pre-installed and pre-configured features

OpenHAB — the most widely used open-source software for home automation. Pre-configured for the PiHome model house, including UI and automation rules. Virtually unlimited customisation options.

Code Server — a web-based interface for editing YAML files and scripts when needed.

Mosquitto — MQTT broker as the core protocol for communication with the PLC, sensors, or Shelly devices.

Pi-hole (optional) — blocks ads and tracking at the network level for every device in your home simultaneously, with no browser extensions required.

Kopia — pre-installed backup solution for the entire PiHome system to your own external drive or storage.

One-click extensions

Via CasaOS you can install additional popular applications at any time, such as: n8n, evcc, NodeRed, and many more.

Openness and documentation

All software and configuration images are published as open-source on OpenTUX. CE declarations of conformity and technical documentation for individual hardware components are available on the respective manufacturers' websites.

FAQ

Who is PiHome Pro suitable for?

PiHome Pro is designed for family homes and cottages. You don't need to be a programmer or a Linux expert. If you can use a smartphone, wire up a light switch, and know where your circuit breakers are — you can handle PiHome Pro. OpenHAB offers an intuitive graphical interface, if–then logic without writing any code, and a large community with guides for almost anything. It's ideal for technology enthusiasts and homeowners who want a smart home tailored to their needs — now and years from now — with no licence fees and no risk of a vendor shutting the system down or raising prices.

PiHome Pro is not suitable if you expect a fully finished turnkey solution with no involvement on your part, or if you have no interest in adapting the system over time. In those cases, closed commercial turnkey solutions are a better fit — though you will pay for that convenience both in upfront cost and vendor dependency.

How do I access my data remotely?

VPN (e.g. WireGuard / Tailscale).

Do I need a specialist electrician?

No. Any qualified electrician will do — they connect the main electrical panel to the RSA terminal outputs in PiHome Pro. A complete wiring diagram is included with every unit.

Can I build PiWork myself?

Yes — guides, images, and source code are shared on opentux.eu. PiHome Pro is for those who want a working unit straight away, without spending time assembling and debugging the installation.

Does the unit meet GDPR requirements?

Data stays physically with you — nothing is sent to third-party servers unless you configure it yourself. You have full control over who can access the system and from where.

Can I build PiWork myself?

Yes — guides, images, and source code are shared on opentux.eu. PiHome Pro is for those who want a working, tested unit without days spent on installation and configuration.

What if my Raspberry Pi or Arduino breaks?

Both platforms are widely available — you can buy them at any electronics retailer. The default OpenHAB configuration and Arduino sketches are provided at handover; recovery takes minutes. You can also back everything up via Kopia.

Which components do we use and where do they come from?

OpenHAB is a robust open-source home automation platform with a long history and a global development team originally from Germany. It has a smaller community than Home Assistant but supports a wide range of devices and standards. It is more stable than Home Assistant and does not go through updates as frequently.

The heart of the board is the Raspberry Pi 5 microcomputer manufactured by a British company. These boards are widely used in industry and are fully certified. Original Arduino Mega boards are made by an Italian company and comply with CE, FCC, and UKCA standards. We use original Arduino boards only. Clones are internationally available but we recommend them for development purposes only.

Further components include certified DC power supplies from Taiwanese manufacturer MeanWell, a Netgear switch from the USA, RSA terminals and a USB hub from Czech companies Elektro Bečov and i‑Tec. The enclosure, circuit breakers, and terminal blocks are from German manufacturer Hager. Krone terminals and Arduino relay boards use Chinese modules where no alternatives exist, but include European declarations of conformity.

Where do the components come from?

We prefer European manufacturers. Components from other regions are used only where no alternative exists — always with a European declaration of conformity.

* Percentages are approximate and based on component purchase prices. Chinese modules carry a European declaration of conformity.
