Keep a clear temperature record across your cold storage.
Monitor storage zones across distribution centers and refrigerated warehouses. Review temperature history, configure alarm delays and escalation, and export records to support your quality checks.

In this world
24/7
Connected cold zones monitored and logged around the clock
- Detect excursions using configured reporting intervals and activation delays.
- Turn a rejected-load dispute into a timestamped, defensible record.
- Cover an entire distribution center without stringing new network cable.
The problem
What goes wrong when no one’s watching.
A silent excursion becomes a six-figure write-off
A failed compressor overnight, a door propped during a long pick, a defrost cycle that runs long — by the morning walk-through the product is already compromised and there is no way to prove when it happened.
Clipboards don't survive a claim or an audit
Manual temperature rounds leave gaps exactly when you need them most. When a customer rejects a load or an inspector asks for history, "we check it twice a shift" is not a record.
Big, cold, metal buildings are hostile to Wi-Fi
Racking, freezer walls, and hundreds of feet of concrete swallow ordinary wireless. Coverage that works at the office fails the moment you push a sensor deep into a freezer.
How FreshControls handles it
Continuous eyes on the numbers that matter.
Continuous monitoring in every zone
Ambient, product-probe, and door readings from receiving to deep freeze, rolled up on one status-first fleet map. Worst-status surfaces first, so a single warning in a hundred-zone warehouse is visible in the fleet summary.
Escalation that wakes the right person
Threshold, door-contact, and offline alarms by email, SMS, and automated voice call — with automatic escalation to the next on-call if the first responder doesn't acknowledge. Configure the delay and escalation schedule for your operation.
Long-range coverage that reaches the back of the freezer
Plan LoRa coverage around racking and freezer walls with a site survey. Current gateway firmware uses Wi-Fi uplink with up to 32 children; Ethernet and cellular backhaul are planned. The platform raises an offline alarm after the configured timeout if a sensor stops reporting.
Audit-ready records, automatically
Every reading is timestamped in the site's local time and retained for HACCP-style logs and load-integrity claims. Each PDF includes a report ID, data digest and file-verification instructions. The SHA-256 checksum of the exact PDF file is available in Reports for comparison, so your quality team can check the file instead of reconstructing a spreadsheet.

Common questions from cold chain teams.
Can one dashboard cover several warehouses and cold rooms?
Yes. Organize monitoring points into areas and sites, configure alarm profiles and escalation teams, and use fleet and regional views to investigate a location. Gateway capacity is a separate hardware constraint: current gateways support up to 32 LoRa children each.
How do we confirm wireless coverage inside a freezer?
Test the selected sensor and gateway at the final mounting points, with doors closed and normal racking and stock in place. Metal walls and equipment affect range. Confirm gateway availability and uplink access before planning the deployment.
What records can our quality team review after an excursion?
Review timestamped readings, configured threshold limits, incident history, recorded acknowledgements and response notes. Export available temperature and alarm-history reports. Your quality team decides whether these records meet its audit or customer requirements.
