Use nymea on the Raspberry Pi 2/3


This tutorial shows you how to install nymea on the Raspberry Pi 2/3. The easiest and recommended way is to use the preconfigured image provided by nymea. If you already have a running operating system and you want to install nymea there, please follow the installation instructions.

The nymea images

We provide images of two different systems for the Raspberry Pi 2/3:

You can check the download section for the overview of all available images and the md5sums.

  • Debian stretch 9.0: This image is based on the default stable debian stretch 9.0 repositories. The kernel, bootloader and Raspberry Pi related packages are installed directly from the raspbian repository and you get all the updates from the official Raspberry Pi community. This image contains also the nymea-networkmanager for an easy wifi setup. We recommend to use this system.

You can download the latest debian version here:

nymea-debian-stretch-9-armhf-raspberry-pi-3.img.xz

nymea-debian-stretch-9-armhf-raspberry-pi-3.zip

  • Ubuntu xenial 16.04.3: This image is based on the default ubuntu stable repositories. The kernel, bootloader and Raspberry Pi related packages are installed from the Ubuntu Pi Flavour Maker. For this system the nymea-networkmanager is not available.

You can download the latest ubuntu version here:

nymea-ubuntu-xenial-16.04.04-armhf-raspberry-pi-3.img.xz

We provide two different image file.

  • The .zip file: This file contains the compressed .img file and should be used if you are not working on a Linux computer. You can find the instructions how to flash a .img image file on your SD card using Windows or MacOS here.

  • The img.xz file: This file contains the xz compressed .img file and makes the flash proccess faster and easier on Linux systems.

Flash the image to the micro SD card:

Assuming you are working on a Linux system, you can flash the images with following instructions. We strongly recommend to use a Class 10 SD card with a minumal size of 2 GB.

Using xzcat

Note: Please replace sdX with the device of your SD card. You can use lsblk to check which device is your SD card.

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install xz-utils

$ xzcat nymea-debian-stretch-9-armhf-raspberry-pi-3.img.xz | sudo dd bs=4M of=/dev/sdX

Using zip file

Note: Please replace sdX with the device of your SD card. You can use lsblk to check which device is your SD card.

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install zip

$ unzip image-file.zip
$ sudo dd if=nymea-debian-stretch-9-armhf-raspberry-pi-3.img of=/dev/sdX bs=4M

Once the process is finished you can insert the micro SD card into your Raspberry Pi 2/3 and power it on.


Login

You can try to connect to the Raspberry Pi using the hostname of the device (nymea):

$ ssh nymea@nymea.local    # password: nymea

Depending on the network setup avahi sometimes does not work. In that case you can connect to the device using the IP address:

Note: Please replace 192.168.0.X with the ip of your Raspberry Pi.

$ ssh nymea@192.168.0.X    # password: nymea

Please make an update on the new system to make sure there is the newest version of nymea installed:

$ sudo apt-get update
$ sudo apt-get dist-upgrade
