Historical Replay for Pharmaceutical
Provide complete environmental and equipment state histories for GMP compliance. Replay cleanroom conditions, equipment parameters, and deviation events with full audit traceability.
Where Things Break Down
Deviation investigations require cross-system data
A deviation report needs environmental data, equipment logs, maintenance records, and personnel activity from the same time window. Pulling this together from separate systems delays the investigation.
GMP audit responses take too long
Auditors ask about conditions at a specific time in a specific room. Your team searches through HVAC logs, BMS exports, and equipment records to build the response.
Cleanroom events are hard to correlate
A pressure excursion, a door opening, and an equipment alarm may all be related, but they are logged in different systems. Seeing the full picture requires manual correlation.
What Sandhed Does Differently
Sandhed records every machine state change, sensor reading, alert, asset position, door event, and work order status continuously. The Timemachine lets you scrub back to any point in time and see your 3D floor plan exactly as it was at that moment. Machines show their actual status. Assets appear where they were. Alerts that were active are visible. You can play events forward at 2x, 5x, or 10x speed to watch how a situation developed. Event markers on the timeline highlight state changes and alerts so you can jump directly to the moments that matter. For longer time ranges, data is automatically aggregated so you can review a full week or month without waiting for raw data to load.
Full State Reconstruction
Scrub to any timestamp and see every machine's operational status, sensor readings, and position exactly as they were. The 3D floor plan rebuilds the complete state including active alerts, door positions, and work order status.
Timeline with Event Markers
A visual timeline bar shows colored markers for alerts and state changes within your selected time range. Hover to see event details, click to jump directly to that moment and zoom to the affected asset.
Variable-Speed Playback
Play events forward at 0.5x to 10x speed to watch how a situation developed over time. See machines transition between states, alerts trigger and resolve, and assets move through your facility in accelerated replay.
Smart Data Aggregation
For short time ranges you get raw sensor data. For longer periods the system automatically switches to 15-minute, hourly, or daily aggregates. You can review a full month of operations without waiting for millions of raw data points to load.
Results You Can Measure
Common Questions
By default, the Timemachine stores a full year of historical data. Your organization can configure a custom start date if you want to restrict how far back users can browse. The system stores all machine states, sensor readings, alerts, asset positions, door events, and work orders continuously.
Everything you see in the live view is reconstructed in the Timemachine: machine operational states (running, idle, warning, error, maintenance), sensor metrics (temperature, OEE, cycle time), asset positions from RTLS tracking, active alerts, door states (open, closed, locked), and work order status with milestone timestamps.
No. The Timemachine runs in a separate mode indicated by an amber banner at the top of the screen. Your live monitoring, alerts, and dashboards continue to operate normally. You can switch between live and historical views instantly.
Data is automatically downsampled based on the time range you select. Ranges under 1 day show raw sensor data. 1 to 7 days uses 15-minute aggregates. 7 to 30 days uses hourly aggregates. Over 30 days uses daily aggregates. This keeps the interface responsive regardless of the time window.
Yes. You can navigate to any specific timestamp an auditor asks about and show the complete facility state at that moment. Machine conditions, sensor readings, alert status, and maintenance activity are all visible. This replaces the manual process of exporting data from multiple systems and assembling evidence.
