Hi n8n community! 
I built a fully automated workflow that turns raw tropical rain footage into ready-to-post ASMR Reels for Facebook (and potentially IG/TikTok later). All running self-hosted on Docker in my local machine.
The workflow is designed for someone living in a tropical area like Merauke, Papua (Indonesia), where heavy rain is daily life — perfect for creating relaxing “Heavy Tropical Rain + Urban Streets” ASMR content that people love for sleep/study/relax.
What it does (end-to-end automation):
- Triggers 2× per day (morning & evening WIT timezone)
- Randomly picks 3–4 pre-recorded rain videos from Google Drive folder (e.g. rainy streets, wet asphalt, distant thunder, motor passing through puddles)
- Generates 90-second ambient rain music using Suno API (prompt: heavy tropical rain on urban streets, deep bass, no vocals)
- Composes everything into one vertical 9:16 video (~45–60 seconds) using fal.ai ffmpeg-api (concat clips + fade transitions + audio overlay)
- Creates poetic ASMR caption + trending hashtags via Groq/Claude (e.g. “Hujan deras malam di Merauke… suara kota tropis yang bikin langsung ngantuk
”) - Uploads directly to Facebook Reels via Graph API (2-step: init + binary upload + publish)
- Logs everything to Google Sheets (date, caption, status)
- Sends Telegram notification if something fails
Tech stack in n8n:
- Schedule Trigger (CRON)
- Google Drive (list & download videos)
- Code node (random selection)
- Suno API (music generation)
- fal.ai ffmpeg-api (video compose)
- Groq/Claude (caption generation)
- HTTP Request (FB Graph API)
- Google Sheets (logging)
Why I built this:
Rain ASMR + urban tropical vibes is exploding in 2026 (especially short-form for sleep), but manual editing is time-consuming. This workflow lets me post consistently 2× a day without touching anything — just upload new rain clips to Drive occasionally.
Current cost per Reel (rough estimate):
- fal.ai compose: ~$0.002–0.005
- Suno music: ~$0.004–0.01
- Groq/Claude caption: <$0.001
→ Total ~$0.01 per Reel (very affordable for daily posting)

Feel free to fork, improve, or ask questions!
- How to make it cheaper (e.g. replace Suno/fal.ai)?
- Add IG/TikTok crosspost?
- Better caption variations?
Looking forward to your feedback!
