Home DIY NAS on Raspberry Pi 4 - installation

What do we need?

Hardware

Raspberry Pi 4B 2GB or more

minimum 16GB microSD card (high speed, i.e. SanDisk High Endurance, etc.)

USB 3.1 hub with external power (we can recommend i-TEC POWERED USB HUBS)

2,5" discs (HDD or SSD) - 2, 4, 8 or more (internal + USB3.0/SATA adapter or external)

Accessories - USB - USB-C adapter, LAN cable, screws

Case

Hint: If we want the home NAS to look compact, the best solution is to get the smallest computer case as possible. There are no limits to the choice of design or colour. Components can be folded/mounted in such a case and the NAS will look compactly.

Software

We use the open source Open Media Vault solution for this application referred to as OMV.

Edit 10/2022

For imaging process, instead of Etcher, we will use Raspberry Pi Imager available for Linux, Mac and Windows. Because of security, new images does not contains default password for pi user and this should be done somehow. The mosr easy way is his utility. To download click on link below.

After installation, choose Raspberry Pi OS Lite (64-bit) under Operating System option.

Choose your SD card (be aware you choose right device!) under Settings, Enable SSH and set default username and password! Click Save and launch Write.

Eject and insert the SD card into the RPi, plug in the LAN cable from your home/company router or network, and start the RPi. The green icon should flash. If we have an ethernet cable plugged in, our RPi probably got the address from the DHCP router. Login to your router to see the list of connected device. Check IP address with hostname raspberrypi . In our case, for example, it's 192.168.1.56. So we're going to use the SSH protocol to connect to our RPi. This is the right time to familiarize yourself with the terminal (the command line in Linux), for example try this guide. It looks scary, but it's the most beautiful thing on Linux. It just works always and everywhere with same results.

SSH support already exists for Windows 10 users built into the shell. For other Windows users, I recommend Putty. I don't have to write any more for Linux users. So, we connect via SSH in terminal. Replace the IP address with your address of raspberrypi rom router. User name and password use from the step of the Raspberry Pi Imager. In our case it can be:

ssh opentux@192.168.1.56

After login, perform the OS update with two consecutive commands:

sudo apt-get update

sudo apt-get upgrade

It'll take a few minutes, then finally install the OMV with command bellow:

wget -O - https://github.com/OpenMediaVault-Plugin-Developers/installScript/raw/master/install | sudo bash

After a while, your own non-commercial DIY NAS is ready to use. For original instructions in English, see here. Once installed, open a web browser and type your RPi address. You're done.

In the next article, we look at the basic configuration.

In this series, we will look at the step-by-step setup of MikroTik devices for home users or a small business (up to 25 people). In the first article, we will focus on the initial setup - we will download Winbox and set up DHCP for the primary network and guest network. Similarly, we will also adjust the WiFi settings.

Alarm from existing PIR sensors in a smart home.Rating: 0%

In a your smart home, PIR sensors may not only be used to switch lights on and off based on motion, it is possible to utilize these sensors to detect the presence of motion in a particular room. This information can be used to create a relatively reliable uncertified home security system. In this guide, you will find the logic for how this can work in the OpenHAB software in our model smart home.

This article describes the self setup of the WireGuard VPN protocol on MikroTik devices with RouterOS version 7 and higher. This phenomenal VPN is very fast, secure, and easily configurable in a home environment. It can be said that it is currently the best VPN for home use available.

Nilan VP18 vs OpenHABRating: 67.2%

We provide tutorial for the connection of the active Nilan recuperation unit, in our case the VP18 K WT type with OpenHAB 3. By communicating via Modbus it is possible to read the whole range of values, but mainly also to control the unit through OpenHAB. This allows us to remotely or programmatically change the performance and ventilation settings depending on the mode (night, cooking, etc.)
