How to set static IP for OpenHAB

How to set static IP for OpenHAB

Do you need a fixed address for OpenHAB outside the range of DHCP addresses that the router assigns? This is sometimes useful, especially if you have, for example, identical RPi as a backup, if there is a problem, simply switch to a backup RPi and you will have the same IP.

The alternative is to set a fixed address for RPi on your router, but you must then do this for both RPi, or adjust it manually. In PiHome, it is important to not change the address of the MQTT Broker, which is currently running on RPi, so static IP is good way.

General settings that work on Debian including openhabian, Raspbian etc. Open to edit the dhcpcd.conf file with the command below:

sudo nano /etc/dhcpcd.conf

and add this part at the end. Change your IP address to the desired ranges as needed

# Static IP address:
interface eth0

# OpenHAB static IP
static ip_address=

#Your router IP
static routers=
static domain_name_servers=

Press the shortcut right CTRL+O to save, confirm with Enter key, and press the right CTRL+X to exit nano editor.

Restart the operating system with the command:

sudo reboot

and your RPi should now have a static IP address:

Tip: In openhabian, the OpenHAB3 version runs also the Network Manager and therefore it may happen that the above setting will cause the RPi to have both a static address and a DHCP address. An alternative, specifically for openhabian, is to set the static address via the network-manager nmcli with the commands below. In this case you can skip setting dhcpcd.conf

Display the name of the connection in the terminal with command:

nmcli connection show

NAME                UUID                                  TYPE      DEVICE  
Wired connection 1  3f5ce7eb-238b-3bea-b16a-5edhsjakakf9  ethernet  eth0   

use these commands to apply static IP address:

sudo nmcli con mod Wired\ connection\ 1 ipv4.addresses ""
sudo nmcli con mod Wired\ connection\ 1 ipv4.gateway ""
sudo nmcli con mod Wired\ connection\ 1 ipv4.dns ""
sudo nmcli con mod Wired\ connection\ 1 ipv4.method manual
sudo nmcli con mod Wired\ connection\ 1 connection.autoconnect yes
sudo reboot

Nilan VP18 vs OpenHABRating: 

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.

Advanced disk cloningRating: 

The classic disk cloning tool in linux is the dd command. This command creates a image of disk or extracts the contents from the image to disk. The dd tool needs to be handled carefully and you need to understand its use. We'll show a more advanced technique of creating a disc image that contains unallocated space. A classic example is when I have a Raspbian operating system installed on a 250 GB disc, but there's only a tiny boot partition (e.g. sda1) and my own operating system partition (sda2) which together have 15 GB. Instead of saving a 250 GB image, I would like to save only two partitions with 15 GB, so that the image is smaller and can be expanded to 16 or 32 GB flash.
