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.
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.
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.

Common Questions
Sandhed integrates directly with Shelly H&T Gen3 sensors, which report temperature and humidity over WiFi via MQTT. These battery-powered sensors publish readings every 60 seconds and require no wiring. The platform also accepts temperature data from Kepware gateways connected to PLCs and process equipment, and from any source via the REST Telemetry API.
Shelly sensors report every 60 seconds. The alert manager evaluates each reading against your configured thresholds immediately on arrival. If a reading crosses a threshold, the alert is created, severity is calculated, and email notifications go out within seconds. For process equipment connected through Kepware, readings can arrive multiple times per second.
Yes. Thresholds are configured per sensor, per metric. You can set a freezer to alert below -18C and above -15C, a cooler to alert above 5C, and a production area to alert outside 18-22C. Each zone has independent high and low thresholds with independent severity levels.
Yes. Every temperature reading is stored in TimescaleDB with a timestamp. You can view historical data for any sensor over any time period. The alert history, including when alerts were created, acknowledged, and auto-resolved, provides a complete audit trail. This data is available for export.
Sandhed tracks the online status of every Shelly device. When a sensor stops reporting, the platform records the offline event and the last known reading. The 3D floor plan shows which sensors are active and which have gone silent, so you can investigate immediately rather than discovering the gap during an audit.

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.
