Do inspectors accept automatic sensor records?

Yes. A continuous temperature record is stronger HACCP evidence than two manual entries per day. What matters is defined limits, a recorded corrective action when exceeded and the ability to present the records – FoodSafetyDocs covers all three.

Do we need Wi‑Fi in the kitchen?

No. Sensors communicate via a LoRaWAN gateway that connects to the internet by cable or office Wi‑Fi. The signal passes through walls and cold-room doors.

How long does the sensor battery last?

Typically 5+ years at a 20-minute interval. The app shows battery status and alerts you below 20 %.

What happens if a sensor stops communicating?

The sensor watchdog detects that no data arrived for more than 2 hours and notifies the responsible people. You get a confirmation once the connection is restored.

How many sensors do we need and what is the price?

One sensor per monitored appliance; one gateway covers a typical site. We prepare a tailored quote for hardware and the monthly IoT module – contact us.

Who it is for

Where automatic monitoring pays off

Restaurants and hotels with many fridges, freezers and cold rooms
Food stores, patisseries and production units with strict limits
Care homes with fridges on every ward
Any operation at risk of losing stock in an overnight cooling failure

What the app does

LoRaWAN sensors with external probe

Industrial Dragino LHT65N sensors with an external probe for freezers (−40 °C to +85 °C), 5+ years of battery life, range of hundreds of metres through walls.

No Wi‑Fi, no cables

Sensors talk to their own LoRaWAN gateway, independent of kitchen Wi‑Fi. Installation takes minutes – stick the sensor on, put the probe inside.

Instant alerts

Limit exceeded, sensor offline or low battery – alerts by e-mail, push, Telegram and in the app. The sensor watchdog checks connectivity continuously.

Automatic HACCP records

Every reading is stored against the right appliance and included in inspection PDF reports – no copying from displays.

Corrective actions & incident handling

When a limit is exceeded the app requests a corrective action (move stock, call service) and stores it with the record – exactly as HACCP requires.

Combine with manual checks

Appliances without a sensor are still logged manually; the app reminds and tracks morning and evening checks.
