Change History
v3.1.126 Aug 2026
Siren fix: once triggered it now runs the full 3 minutes even if the hatch is closed straight away. Previously closing up stopped it after a couple of seconds. Pause Alarm and Disarm still silence it instantly.
Dashboard26 Aug 2026
Battery chart now covers 24 hours instead of 1, plotted against real time so a Go Live burst shows as a spike rather than stretching the graph. History reloads once a minute rather than every 5 seconds during Go Live. This change list added.
v3.1.025 Aug 2026
Intruder siren now cycles 3 min on, 1 min silent, repeating while the sensor stays tripped, instead of sounding continuously. Spreader lights keep flashing right through the quiet gaps. A 30 s guard stops a flickering sensor restarting the cycle.
v3.0.017 Aug 2026
Test Lights became a three-state control: Auto (lights pulse only during a real alarm), Flash (pulse continuously) and Off (forced off even during an alarm).
