## Version history (last 5 releases)

### 1.2.6 — 2026-09-27

Alert styles, per sensor. A sewage float can scream while the shop doorbell just chimes, or a door sensor can simply tell you it opened and clear itself.

Your own alarm sound for each sensor, set on your own phone. What you choose does not change anybody else's.

Trigger sensitivity per sensor, so a momentary button press still holds the alarm until somebody acknowledges it.

"Not me" — hand an alarm to the next person on the call list without acknowledging it. It comes back to you in five minutes if nobody takes it.

Acknowledge from your watch, and the alarm stops on your phone too.

The app now opens on a lighter look.

Fixes: one notification per alarm instead of one for every reminder, a sensor that has gone quiet no longer reads as fully offline, and signing out stops alarms being sent to that phone.

### 1.2.5 — 2026-09-22

- "Not me" button — hand an alarm to the next contact without acknowledging it; comes back to you in 5 minutes if nobody takes it
- Apple Watch — acknowledge or pass an alarm from the wrist
- Pressing 1 on the voice call now silences every other device, not just the phone
- Alarm notifications no longer linger after you acknowledge
- WiFi signal badge on dashboard tiles — green when strong, red when weak, greyed with a slash when the sensor is offline
- Metric buttons on the sensor detail screen now drive that sensor's dashboard tile — sparkline and scrolling readouts. Per sensor, per user, so your choices don't change Danny's
- Relay control fixes, and a new watch app icon

### 1.2.4 — 2026-09-19

- Sensor name and status lamp moved to the top of the tile; chart is larger in both directions
- Readings roll one at a time with a caption above each value, so you always see a complete reading
- Alarm history now shows who acknowledged an alarm, including alarms answered by phone
- Sensor detail screen shows the status correctly when an alarm is acknowledged but not yet cleared, and you can acknowledge from that screen
- Manual relay control for R4 sensors
- Fixed alarm times showing in UTC instead of your local time
- Acknowledging on one device now stops the alarm on your other devices
- New look throughout, with the Daylight theme retired
