Networking
To keep network traffic away from my house WIFI network, and because some Arduino boards are not WIFI enabled, I have decided to use a wired network for the data.
This meant that I needed a rack mounted network switch, so scouring the local pages I found a HP 2530 Network Switch
To provide the IP4 network addresses I have deployed the kea DHCP4 application on a Raspberry Pi using an Ansible Playbook
