## What is BluSi?

BluSi turns your phone into your key. Open the front door, the garage, the cellar or a utility room, and manage who can come in, with no keyring and no spare keys to cut.

SIMPLE OPENING
Open from the app, or automatically as you reach the door. Your choice.

MANAGE YOUR ACCESS
Give access to your family, your relatives or a contractor straight from the app. Create temporary codes for a tradesperson or a delivery, with an end date and time. Remove any access whenever you want.

VIDEO INTERCOM
A visitor calls you from the door. You see them, you talk, and you open during the call. The call can ring on several phones in the home; the first to answer handles the request.

FOR BUILDINGS
Main entrance, garage, cellars and shared rooms from a single account. Linked doors let one access cover a door and its associated entrance.

SECURE AND SWISS
Data hosted in Switzerland. No lost keyring to replace: a mislaid device is revoked from the app.

## Version history (last 5 releases)

### 4.0.0 — 2026-07-15

New in this version:
- Time-based access windows now follow the door's local time.
- Try every feature on a demo box, no hardware needed (account required).
- A smoother map with a clearer loading state and better centering.
- Clearer temporary access windows, with support for linked doors.
- Stability and performance fixes.

### 3.2.0 — 2026-06-23

This update improves access calls and the way you manage your doors.

• Ring several phones: an access call can ring several residents at the same time. The first to answer takes the call and ringing stops on the other phones.
• "Allow video calls" preference: turn receiving calls on or off from your preferences. When off, you no longer appear as a reachable contact and won't ring.
• Linked doors: one access can cover a door and its linked entrance (for example a lobby and a garage), including for temporary access codes.
• Improved call reliability and interface refinements.

Thanks for using BluSi. We welcome your feedback at support@blusi.ch.

Video calls at the door
- Door video calls ring your phone like a real call, even when the screen is locked or the app is closed.
- Set the ringtone and call duration in My preferences. With ringing off, the call arrives as a notification.
- The call shows who is requesting access and which door. An unidentified visitor appears as "Anonymous".

More reliable notifications
- Fixed an issue that stopped some notifications from arriving.
- Notifications now recover on their own after a reinstall or a permission change.

Access requests
- New tracking banner with the recipient, the door, and the time remaining.
- Predefined quick messages you can add with one tap.

Per BluSi Box help and support
- Each BluSi Box can show its own contacts (phone, email, other) and opening hours.

Security and privacy
- Offline access is limited to 12h since the last check; a lost phone stays revocable, even in airplane mode.
- Optional diagnostic log (off by default).

Various fixes and stability improvements.
