UI-saved automations land in /var/lib/hass/automations.yaml, but HA won't load them unless configuration.yaml has \`automation: !include automations.yaml\`. The Nix-managed config didn't have it, so HA's post-save reload found no automations and timed out. The NixOS HA module's renderYAMLFile post-processes the generated YAML to convert quoted bang-strings into real YAML tags (see the sed step in nixos/modules/services/home-automation/home-assistant.nix), so a plain Nix string is enough — no escape-hatch needed. Pre-create the three include targets via systemd.tmpfiles so HA doesn't fail at startup if the user hasn't saved anything yet. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
