+# n8n Flow Ideas
+
+Backlog of automation ideas to build. Implement via n8n UI at https://n8n.nuclide.systems or API.
+
+## 🔴 High priority
+
+### Homelab Health Check (hourly)
+**Status:** Prototype as bash/systemd on nuc. Migrate to n8n.
+**What:** Every hour — check critical containers (Pocket-ID, LiteLLM, Grafana, Homarr, Nextcloud, HA), disk usage, key HTTP endpoints. Auto-restart stopped containers. Send Gotify alert for crash loops, disk >90%, VM down.
+**Nodes:** Cron → SSH (per host, check docker ps) → IF (status != running) → Execute Command (docker start) → Gotify HTTP.
+**Gotify token:** Az9NpC-m1jjf571 (homelab-health app), URL: http://192.168.1.40:10003
+
+### Backrest backup result notification
+**Status:** Not built.
+**What:** After each Backrest snapshot (Pocket-ID, media, services plans), notify Gotify with summary: plan name, files added, size, duration, next run. On failure, priority 10 alert.
+**How:** Backrest has webhooks (post-backup hook) → n8n webhook → Gotify.
+**Nodes:** Webhook → Parse Backrest payload → Gotify.
+
+### Nextcloud/Paperless → Docling → embeddings pipeline
+**Status:** Docling MCP deployed; pipeline not built.
+**What:** Watch Nextcloud for new documents → send to Docling for OCR/extraction → chunk + embed → store in Chroma → index in LobeChat knowledge base.
+**Nodes:** Cron (poll Nextcloud activity) or Nextcloud webhook → HTTP (Docling API) → HTTP (Chroma upsert) → optional Gotify confirmation.
+
+## 🟠 Medium priority
+
+### HA entity alert → Gotify bridge
+**Status:** Gotify notify platform configured in HA but no automation rules written.
+**What:** HA automations for: EV charger state changes, door open >10 min, CO₂ > 1200 ppm, low battery (<20%) on sensors. Send formatted Gotify push via n8n or directly.
+**Nodes:** HA webhook automation → n8n webhook → format message → Gotify.
+
+### Gitea repo activity digest (daily)
+**Status:** Not built.
+**What:** Every morning at 08:00, pull yesterday's commits across all homelab repos, format into a digest, send to Gotify (priority 3 — FYI).
+**Nodes:** Cron → HTTP (Gitea API /repos/fkrebs/*/commits?since=yesterday) → Code (aggregate) → Gotify.
+
+### Immich face/album auto-tagging
+**Status:** Not built.
+**What:** On new Immich upload, run face recognition → auto-assign to album based on person. Optional: generate caption via LiteLLM vision model.
+**Nodes:** Cron (poll Immich /api/asset?isFavorite=false&order=asc) → HTTP (Immich album API) → optional LiteLLM caption.
+
+### WAL-G backup health monitor
+**Status:** bash-level only; silent stall went undetected 13h.
+**What:** Every hour, query Garage S3 for latest WAL-G backup timestamps per DB (immich, lobe). If last backup > 26h, send Gotify alert priority 8.
+**Nodes:** Cron → Execute Command (mc ls on Garage) or HTTP (Garage S3 API) → IF (age > 26h) → Gotify.
+
+### Karakeep → memos enrichment (extend existing flow)
+**Status:** Karakeep-to-memos flow exists; basic save only.
+**What:** Extend: after saving link to Memos, also: (1) fetch page via crawl4ai MCP for summary, (2) generate tags via LiteLLM, (3) update Memos entry with summary + tags.
+**Nodes:** Extend existing Karakeep-to-memos → HTTP (LiteLLM /v1/chat/completions) → HTTP (Memos PATCH).
+
+## 🔵 Nice-to-have
+
+### Coder workspace lifecycle alerts
+**Status:** Planned (see memory: coder-monitoring-gotify).
+**What:** When a Coder workspace starts/stops/fails build, send Gotify notification with workspace name, owner, duration.
+**Nodes:** Cron (poll Coder API /api/v2/workspaces) → compare state → Gotify on change.
+
+### n8n workflow backup reminder
+**Status:** Covered by this repo's daily sync cron.
+**What:** If sync cron detects uncommitted changes, send Gotify reminder to review new/changed flows.
+
+### Paperless document classification
+**Status:** Not built.
+**What:** On new Paperless document → send text to LiteLLM → suggest title, tags, correspondent, document_type → auto-update via Paperless API.
+**Nodes:** Paperless webhook or cron poll → HTTP (LiteLLM) → HTTP (Paperless PATCH /api/documents/{id}/).
+
+### Traccar GPS geofence → HA
+**Status:** Not built. Traccar running on CT 104 :13005.
+**What:** When a tracked device enters/leaves home geofence → call HA webhook to trigger automations (e.g. arm/disarm alarm, preheat EV).
+**Nodes:** Traccar webhook → HTTP (HA webhook).

+A daily cron on CT 104 (03:30) exports all workflows → splits by name → commits + pushes here.
