Weather Warning

⚠ Weather Warning — IC10 Storm Alert

Flashlight · Klaxon Alarm · 15s Lead · storm-aware

A compact, robust IC10 script that watches your weather station and warns you in time before the next weather event — with a warning light for the whole countdown and a klaxon siren in the final seconds. All devices are addressed by prefab type + labeler name (lbn/sbn), so no fixed pin assignments are needed. Values are written only on state change, meaning no unnecessary network traffic.

Features

• Warning light turns on as soon as an event is pending and stays on for the entire countdown.
• Klaxon alarm sounds during the final 15 seconds before the event (lead time is adjustable).
• Status code on the IC housing display (db Setting) for quick diagnostics.
• Write-on-change: light, alarm and status are written only on an actual state change.
• Cleanly named access via labeler name — other devices of the same type on the network are left untouched.

Special case: negative event time

Some builds / weather stations report a negative remaining time for the next event and skip the regular 0–15 second window entirely. With classic "only if time > 0" logic the siren would never fire in that case.

This script handles exactly that: the alarm is gated on time ≠ 0 instead of time > 0. As a result it fires both during the normal countdown (0 < t ≤ 15) and on an overdue, negative remaining time ([b]t < 0)[/b] — while the regular "event running" tick at exactly t = 0 stays silent as before. Both cases are distinguished by their own status codes, so the display tells you directly which path is active.

Setup / Wiring

• Weather Station — labeler name: Atmo WeatherStation
• Flashlight (warning light) — labeler name: Weather Flashlight
• Klaxon Speaker — addressed by type, i.e. all klaxons on the data network fire. To trigger only one specific speaker, switch sb to sbn with a labeler name in the script.
• IC Housing + IC10 — carries the script; db is the housing itself.

Adjust the labeler names at the top of the script to match your labels. Prefab hashes are CRC32-verified; double-check in the Stationpedia if in doubt.

Status codes (db Setting)

• 0 — calm, no event
• 1 — scheduled (light on, t > 15)
• 2 — countdown (alarm, 0 < t ≤ 15)
• 3 — event running (light on, alarm off, t = 0)
• 4 — overdue (alarm, t < 0)

⚙ Adjustable values

• alarmLead — lead time in seconds (default 15)
• alarmSound — klaxon sound via Mode (default 12)
• alarmVolume — volume (default 100)

Notes

• Atmosphere required: A klaxon needs air pressure to be audible — on the bare Martian surface it stays nearly silent. For a pure function test, place the speaker in a pressurized room.
• Separation: Since the klaxon is addressed by type, all klaxons on the reachable data network respond by default. For multiple independent sirens, use separate networks or switch to named access.
