Wiliot Ambient IoT Cold Chain Temperature Monitoring

Wiliot is an ambient IoT company headquartered in Israel, founded by the leadership of millimeter-wave chip maker Wilocity, with offices in the US, the UK, Portugal, Australia and Taiwan. It tackles the blind spots of pallet- and zone-level cold chain monitoring, where perishables spoil and shrink without a clear record of which cases were exposed.

Battery-free Bluetooth IoT Pixels are applied to cases at source by suppliers or manufacturers. Fixed and mobile network infrastructure in DCs, stores, cold storage and refrigerated trailers energizes the pixels and captures temperature, dwell time and location. The Wiliot Physical AI platform builds a timestamped temperature history per SKU or lot, issues product-specific excursion alerts and pushes compliance records to ERP, WMS or food safety systems. Users include grocery retailers, quick-service restaurants, food distributors, pharma and third-party cold storage.

• IoT Pixels: battery-free Bluetooth sensors applied to cases at source.
• Network infrastructure: fixed readers in DCs, stores and cold rooms plus mobile deployment on refrigerated trailers.
• Case-level temperature history: a timestamped record per SKU and lot across the cold chain.
• Excursion and dwell-time alerts: real-time alerts when products approach shelf-life or safety thresholds.
• Automated compliance: documentation supporting FSMA 204, GDP and HACCP workflows.
• Cloud-to-cloud integration: SDK and open APIs feeding ERP, WMS and food safety platforms.

• A supermarket chain in Vietnam can tag chilled and frozen cases at suppliers and monitor them through DCs and stores.
• A quick-service restaurant group can cut temperature violations at the receiving dock.
• A third-party cold storage operator can give customers case-level temperature history as a value-added service.

• The solution page cites up to 90% reduction in temperature-related spoilage and 99%+ case-level accuracy for location and temperature.
• Infrastructure costs are stated as 5-10 times lower than RFID, with average ROI in about one year.
• Compliance records are generated automatically, removing manual temperature logging.
• Alerts identify the specific at-risk products rather than whole zones or shipments.

Retailers and food distributors are shifting from pallet-level data loggers to item- and case-level sensing as food safety traceability rules tighten and perishable shrink stays high. Modern grocery, convenience and food service chains expanding in Vietnam and Southeast Asia face similar pressure to cut spoilage and document cold chain compliance.

Wiliot is headquartered in Israel with offices in California, Texas, Arkansas, New York, London, Portugal, Ukraine, Australia and Taiwan. Investors shown on its site include Amazon, Avery Dennison, Maersk, PepsiCo, Qualcomm, Samsung and Verizon Ventures.
