Temperature Monitoring

Know the Second a Cooler Drifts,Not the Day a Batch Is Lost

A 2-degree drift in a freezer or pasteurizer can destroy product, trigger recalls, and halt production. Sandhed maps live temperature data from Shelly sensors onto your 3D floor plan so you see every cold chain risk the moment it starts.

The Problem

Where Things Break Down

Temperature excursions cost food and pharma manufacturers millions every year in spoiled product, failed audits, and production shutdowns. The problem is rarely that nobody checks. The problem is that readings live on individual sensor displays, paper logs, or disconnected dashboards. By the time someone notices a cooler running warm, the product inside may already be compromised. And the audit trail to prove what happened? That takes hours to reconstruct from scattered records.

Manual temperature logs miss excursions between checks

If someone checks a cooler every 4 hours, a temperature spike at hour two goes undetected until hour four. By then, the product may have been out of range for 2 hours and the entire batch is at risk.

Up to $25,000 per spoiled batch in food production

Sensor data is scattered across devices and paper logs

Each freezer, cooler, and process area has its own sensor display. Comparing readings across zones means walking the floor or pulling data from multiple systems. Nobody has a single view of the full cold chain.

2-4 hours to reconstruct temperature records for an audit

Alerts arrive too late or go to the wrong person

A local alarm beeps on a freezer at 2 AM, but nobody is nearby to hear it. Or the building management system sends an email to the facilities team instead of the quality manager who needs to make the hold decision.

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.

FAQ

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.

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.

Compliance & 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.
