Daily Open Checklist

Power on the Helm NUC. Wait ~30 seconds for HelmOS to boot.
Power on attached audio, video, and lighting gear.
Open the operator tablet to Cuemaster (http://10.0.0.1:3000/).
Verify the topbar shows "Show Active" with a green indicator.
Verify the Nodes tab shows every expected board as Online.
Verify no Active Alerts on the Overview tab.
Confirm the Bridge maintenance key is in the OFF position.
Press the GREEN Show Start button on the Bridge.

During the Show

Watch the Active Alerts count on the Overview tab — anything above zero needs attention
Activity log fills with cue-fire events in real time
If a guest reports a missed effect, check the Activity tab — the sensor event will be logged even if the cue failed

Emergency Stop

Two paths, both effective:

Press the RED mushroom on the Bridge — physical, instant
Click the red E-Stop button in the Cuemaster topbar — software, requires browser focus

Both abort every active cue and broadcast STOP to every Polaris node.

End of Day

Press the YELLOW Show Reset button on the Bridge — ensures no cues are mid-flight.
Power off A/V gear.
Leave the Helm NUC running — it idles at minimal CPU.

Common Mid-Show Issues

Symptom	Action
One node went offline	Check the Activity log for the node ID; check power + Wi-Fi at the node's physical location
An effect did not fire	Activity log will show whether the sensor event arrived; if yes, check wiring at the Polaris node
Cuemaster tablet lost connection	Try refreshing the browser; check Wi-Fi association
A scheduled cue did not fire	Verify the system clock; verify the schedule is enabled in Compose
