Resources#

Install procedure#

Boot the HP thin client from an Ubuntu Desktop 24.04 usb, and then follow this procedure to install the HA-OS to the built-in SSD.
Then simply remove the USB and reboot.
You get a HomeAssistant prompt on console 1, and a root prompt on console 6 (just press enter)
The web console is available at http://192.168.2.8:8123, first create a user.

Customization#

• Add DSMR integration and plug a P1 usb meter in the HP thin client. Also you can enable some initially disabled entities, like voltages and current. You can entities from this integration to the energy dashboard.
• Add the Frontier Silicon integration, that should allow operating the Imperial DABMan internet radio.
• Install the Mobile App integration (or was it already present after vanilla install?), anyway, you should be able to add your phone, but using the HomeAssistant app on your phone.
• Install the SolarEdge integration. Also add this in the energy dashboard. You do need an API key, I got that straight away as a reply on a mail to mail solar installer SolarHVT. Zie ook deze instructies
• Create an empty dashboard ("Rommel"), here you can add stuff (you cannot add stuff to the default set of dashboards)
• arrange firewalling via the raspberry pi by:
  • adding one POSTROUTING rule:
    iptables -t nat -A POSTROUTING -p tcp -d 192.168.2.8 --dport 8123 -j SNAT --to-source 192.168.2.19
    
  • add an extra nat rule to the knockd config:

[options]
	UseSyslog

[openALL]
	sequence    = 4381, 3090, 9672
	seq_timeout = 5
	command     = /sbin/iptables -I INPUT -s %IP% -p tcp -j ACCEPT;/sbin/iptables -t nat -A PREROUTING -p tcp --dport 8123 --source %IP% -j DNAT --to-destination 192.168.2.8:8123
	tcpflags    = syn

[closeALL]
	sequence    = 9672, 3090, 4381
	seq_timeout = 5
	command     = /sbin/iptables -D INPUT -s %IP% -p tcp -j ACCEPT;/sbin/iptables -t nat -D PREROUTING -p tcp --dport 8123 --source %IP% -j DNAT --to-destination 192.168.2.8:8123
	tcpflags    = syn

TODO#

• integration of klikaan klikuit
• how can I have simple firewall protection?
