Home automation: KNX and Home Assistant articles, section tidy-up

[fjp]

Summary

Two new pages in the home-automation section, and a tidy-up of the section so everything goes live together.

New pages

• From ETS to Home Assistant: Generating the KNX Configuration (/projects/home-automation/ets-to-home-assistant/)
  • The options for getting a KNX project into Home Assistant: the KNX panel, YAML by hand, ets-to-homeassistant, nickol-knx-mcp, and an own generator.
  • The generator pipeline (per-room YAML packages, areas, a generated phone dashboard) and its rules, with a made-up example.
  • A section on a common pitfall: two devices answering the same GroupValueRead, with a sequence diagram, how to find the second responder (group monitor, xknxproject script), and the fix in ETS.
  • Phone screenshots of an invented demo house, generated with the same dashboard script against a local demo Home Assistant. No real names, addresses or values.
  • A short hardware note: a Beelink EQ14 mini PC under Proxmox, linked to Beelink's own shop page (plain link).
• Velux Roof Windows with KNX Buttons, through Home Assistant and the KLF 200 (/projects/home-automation/velux-klf200-knx/)
  • Home Assistant as the bridge between KNX buttons and Velux io-homecontrol products, with a made-up example package.
  • The example is wrapped in Liquid raw tags, so the page shows the Home Assistant templates unchanged.
  • What the end of the KLF 200 means: the KLF 150 has no local API; for new installations the VELUX ACTIVE gateway (KIG 300) through HomeKit Device; Somfy TaHoma and OpenKNX as other routes, with sources.
  • Screenshots of the same demo house.

All addresses, device addresses and entity names in the examples, diagram and screenshots are invented.

Section tidy-up

• Overview (/projects/home-automation/, URL unchanged):
  • titled "Home Automation";
  • "Weather station" and "Lighting control" typos fixed;
  • the old Raspberry Pi test sentence replaced by the current setup, with links to the new pages;
  • the empty table of contents removed.
• 2022 Raspberry Pi 4 setup (/projects/home-automation/setup/, URL unchanged):
  • titled "Raspberry Pi 4 Home Assistant Setup (2022)", with an archive notice.
  • Broken images fixed: the header image name; eight installation screenshots that were never committed (the steps stay as text); a wiki page used as an image (now a link).
• Redirects: four pages (the overview itself, the setup page, Voltus, KNX button selection) had redirect_from: /projects/home-automation/.
  • jekyll doctor reported four redirect pages on the overview's own URL; the overview only won because Jekyll writes collection documents last.
  • All four entries are removed.
• Other fix: a doubled folder in an image link on the KNX button selection page.
• Sidebar:
  • "Home Automation" (Voltus, KNX Button Selection);
  • "KNX + Home Assistant" (the two new pages);
  • "Older projects" (the 2022 Raspberry Pi 4 setup and the 2019 temperature and humidity page).

Checks

• Local Jekyll build: all 267 internal links, images and anchors of the section's seven pages resolve.
• The code blocks on the built pages equal their source.
• Both YAML examples pass Home Assistant 2026.9.4's configuration check as rendered; the Velux example also passes a native behaviour test.
• Images carry no metadata.
• gitleaks finds nothing.
