Temperature Monitoring for Food & Beverage
Track freezer, cooler, and pasteurization temperatures in real time. Get alerts when cold chain conditions drift before product quality is compromised.
The Problem
Where Things Break Down
A freezer door left open at midnight spoils $20,000 in product
Walk-in freezers and coolers are only as reliable as the last person who closed the door. Without continuous monitoring, a 4-hour gap between checks can mean the difference between safe product and a disposal event.
Pasteurization temperature drops go unnoticed mid-batch
If the pasteurizer drops below the required hold temperature during a batch, the entire run may need to be reprocessed or discarded. Local alarms exist but they are easy to miss on a noisy production floor.
Audit prep takes days of digging through paper logs
When an auditor asks for 90 days of temperature records across all cold storage zones, the quality team spends days collecting data logger downloads, paper logs, and maintenance records to build the timeline.
Our Approach
What Sandhed Does Differently
Sandhed connects directly to Shelly temperature and humidity sensors via MQTT. Every reading is mapped to the sensor's physical location on your 3D floor plan in real time. You see color-coded overlays showing which zones are in range and which are drifting. When a reading crosses your configured threshold, the system creates an alert, determines severity automatically based on how far the reading has drifted, and sends email notifications to the right people. If the temperature returns to normal, the alert auto-resolves. Every reading is stored in TimescaleDB for audit trails and trend analysis.
Live Temperature Mapping
Every Shelly sensor reading displayed as a color-coded overlay on your 3D floor plan. See freezers, coolers, production areas, and storage zones at a glance with current temperatures and trend direction.
Configurable Threshold Alerts
Set high and low temperature limits for each sensor. When a reading crosses a threshold, Sandhed creates an alert with severity calculated automatically. Warning for small drifts, critical for readings 20% or more beyond your limit.
Automated Alert Routing and Email
Alerts go to subscribed team members filtered by severity. Quality managers get critical cold chain alerts. Maintenance gets warning-level equipment drift. Each person sees what they need to act on.
Historical Trend Analysis
All temperature readings stored in time-series format. View historical overlays to spot gradual equipment degradation, identify recurring drift patterns, and generate audit-ready records for any time period.

Environmental Monitoring
Humidity creeping up in a cleanroom or pressure dropping in a controlled area can compromise an entire production run. Sandhed puts live environmental data from every sensor onto your 3D floor plan so you catch problems the moment conditions change.
View SolutionCompliance & Audit Trails
Most facilities piece together audit documentation from spreadsheets, paper logs, and disconnected systems. Sandhed records every action, threshold breach, and maintenance event automatically, so your compliance evidence is ready before anyone asks for it.
