SeekSoft TempT is the cold chain module of AOPL's proprietary SeekSoft™ middleware. It sits between the physical sensing layer and the enterprise systems, and its job is narrow and unglamorous: take every reading from every device, attach an identity to it, and keep it forever in a form a regulator will accept. Readings arrive from RFID sensor tags, wireless IoT probes, reefer telematics units, BMS controllers and handheld readers over MQTT, Modbus, BACnet/IP, OPC-UA and REST — and leave as batch-linked thermal histories, excursion events and validated reports.

The platform is deliberately device-agnostic. Most large organisations already own three or four incompatible logger fleets; replacing them is expensive and unnecessary. TempT ingests them all and normalises the data into one model, so the quality team works from one record rather than five portals. Deployment runs cloud (Indian data residency), on-premise, or fully air-gapped for defence and government installations, with edge gateways that buffer locally when connectivity fails and reconcile automatically when it returns.

A cold room is not one temperature. It is a field of temperatures that shifts with load, door cycles, defrost and ambient conditions — which is why thermal mapping comes before sensor installation, never after. AOPL runs multi-point mapping studies loaded and empty, identifies hot and cold spots, and then places permanent probes where the evidence says they belong. Cold rooms, blast freezers, ripening chambers, ante-rooms, dispatch docks and ambient QC stores are covered by one wireless network using LoRaWAN, BLE mesh or wired PT100/PT1000 probes depending on structure and RF conditions.

The instrumentation extends past temperature. Door-open dwell, compressor runtime, defrost cycles, DG changeover and mains failure are all captured, because they are the causes behind most excursions and they turn an alarm into a diagnosis. Where AOPL has also delivered the building's IBMS, the cold chain layer integrates directly with refrigeration plant controls and energy sub-metering — the same practice discipline that runs our Integrated Building Management Systems business.

Traceability fails at the dock door, where people are asked to scan things while trucks wait. AOPL removes the human step: RFID dock-door portals, forklift-mounted readers and handheld terminals capture every pallet, case and tote as it moves, with no stopping and no line-of-sight. Each read generates a GS1 EPCIS 2.0 event — shipping, receiving, aggregation, disaggregation, transformation — carrying the SSCC, GTIN, batch, quantity, GLN and timestamp that traceability regulations actually ask for.

This is what makes the temperature record commercially useful. When a sensor tag is paired to a pallet at packing and the pallet is read at every handover, thermal history and custody history become one timeline, and liability stops being a matter of opinion. It is also the mechanism behind precise recalls: instead of withdrawing a whole production lot, you withdraw the eleven pallets that actually experienced the excursion. For food businesses exporting to the United States, the same event data is the raw material for FSMA 204 Key Data Elements at Critical Tracking Events, retrievable within the rule's 24-hour window ahead of the 20 July 2028 compliance date.

An alert delivered after the product is gone is a report, not an alert. The TempT rule engine evaluates at the edge and notifies in under 30 seconds, using five rule classes rather than a single threshold: absolute limits, duration-weighted breaches, mean kinetic temperature (MKT) against the product's stability budget, rate-of-change signatures that reveal a thaw or a failing compressor, and predictive pre-alarms that fire when the trajectory — not the current reading — will breach.

Equally important is what the engine does not send. Defrost windows, scheduled door cycles and sensor dropouts are suppressed intelligently, because alarm fatigue is the most common reason monitoring systems get ignored. Every genuine event enters a three-tier escalation with acknowledgement SLAs — operator, then supervisor, then quality head — across SMS, WhatsApp, email and voice call, and opens a deviation record that must be closed with root cause and CAPA before it leaves the queue.

The regulatory direction of travel is unambiguous: continuous, attributable, electronic records are replacing hand-written registers. India's revised Schedule M (G.S.R. 922(E)) has been in force for all manufacturers including MSMEs since 1 January 2026, bringing IQ/OQ/PQ qualification of cold storage equipment, automated deviation logging and documented calibration. WHO GDP is enforced through CDSCO for distribution; exporters answer additionally to 21 CFR Part 11, EU Annex 11, EU GDP 2013/C 343/01 and USP <1079>; food businesses face FSSAI requirements at home and FSMA 204 from 20 July 2028 abroad.

TempT is built for that evidentiary standard rather than retrofitted to it. Records are immutable and attributable under ALCOA+ principles, every change carries who-what-when-why, electronic signatures support review and release, and calibration certificates, due dates and drift history live with the sensor that produced the data. AOPL delivers the validation package — user requirement specification, IQ, OQ, PQ protocols and execution — as part of the project, not as a chargeable afterthought.

Some consignments have no second copy. Cell and gene therapies, autologous products, biobank samples, reference standards and donated blood components cannot be re-manufactured if a freezer fails overnight. AOPL instruments −86°C ULT freezers, liquid nitrogen vapour-phase dewars, dry-ice shippers and blood bank cold chains with four-wire PT100 probes, redundant independent sensing paths per unit, and alarm escalation that assumes the first two people will not answer the phone.

Blood banking adds component-level complexity: whole blood and red cells at +2 to +6°C, platelets at +20 to +24°C under continuous agitation, plasma below −30°C — each with its own limits, agitation requirements and issue records. TempT tracks bag, vial and aliquot identity through storage, issue, return and disposal, giving hospitals and biobanks a chain of custody that holds up to NABH and accreditation review. Cryogenic areas additionally carry oxygen-depletion monitoring and safety interlocks, because the risk there is to people as well as to product.
