Blueprint Studio 2.4.0 — PWA Power, Blueprint Magic, SFTP & SSH Supercharged
Blueprint Studio 2.4.0 — PWA Power, Blueprint Magic, SFTP & SSH Supercharged
Released: March 20, 2026
This release transforms Blueprint Studio into a more native, mobile-friendly, and powerful automation IDE — right inside Home Assistant.
You can now install Blueprint Studio as a real app on your phone, tablet, or desktop (HTTPS connection with secure certificates required). Blueprints have never been easier to create or use. SFTP and SSH got major usability and security upgrades. And behind the scenes: faster streaming, bigger uploads, cleaner code, and many long-standing rough edges polished away.
✨ Headline Features
Instant Blueprints — “Use Blueprint” Form
- Brand-new side-by-side form that turns any blueprint into a ready-to-save automation
- Smart controls: entity pickers, sliders, toggles, time/date pickers, duration spinners, template editors…
- Live YAML preview updates as you type (debounced)
- Two-way sync: edit the blueprint YAML → form refreshes automatically
- Save directly to
automations.yaml(auto-reloads HA) or to a new file - Persists across browser refreshes and tab switches
One-Click Blueprint Conversion (Ctrl/Cmd + K → Convert to Blueprint)
Improved multi-pass extraction now intelligently pulls out:
- Entities → domain-filtered selectors
- Magic numbers (brightness, temperature, percentages…) → number inputs with units & limits
- Delays,
for:durations, time triggers, automation modes, condition states - Safe naming, collision avoidance, incrementing suffixes
- Optional description field support
Full Progressive Web App (PWA) Support

SSH & Terminal Overhaul
- Secure public-key (RSA/Ed25519/ECDSA) + password authentication
- Save, edit, delete SSH hosts with one-click auto-connect
- Credentials stored safely in browser (no more plaintext on disk)
- Command injection fixes + proper argument escaping
- Auto-reconnect on last-used host
SFTP — Now on par with local file tree
- Modified-file dots, bulk actions, pin-to-top favorites
- Drag-and-drop ZIP → extract directly on server

Modern Markdown & AI Experience

Performance & Large-file Breakthroughs
- True streaming for video/audio previews and folder ZIP downloads

- Zero-copy file serving, raw-byte SFTP handling
- No more memory spikes on big transfers
Security & Stability Polish
- SSH command injection fixed (
shlex.quote) - Main API now uses proper HA auth middleware (no custom bypass)
- Removed plaintext credential leaks on disk
- WebSocket reconnection logic → real-time updates survive long idle periods / network drops
- Fake filesystem watcher removed (cleaner, less noise)
Quality-of-Life & Editor Improvements
- Format Code now respects your tab size & spaces/tabs preference
- Global search: All/Files/Entities tabs, inline & file-level replace, dismiss matches

__MACOSX,.DS_Store) - 10-language localization refresh
- Many more file types recognized & editable out-of-the-box
Blueprint Studio 2.4.0 feels faster, safer, and far more capable — especially if you live in blueprints, remote servers, or want your automation workbench available anywhere.
Enjoy the upgrade — and happy automating! 🚀
