Wireless curing sensors: a CurNext field playbook for reliable installs

Install quality decides data quality

Wireless curing sensors only create value if crews trust them on pour morning. A beautiful dashboard cannot recover from a probe placed in the wrong zone, a gateway buried behind wet decks, or a device that never joins the network. This playbook mirrors how CurNext field and operations teams commission CN-CC fleets on active sites.

Plan placements with the pour, not after it

Before trucks arrive, mark probe locations on the pour plan with the superintendent and structural contact.

• Prefer mid-depth for mass elements when equivalent age for the core controls strike or loading.
• Prefer near-surface positions when finishing, blanket, or heater decisions dominate.
• Avoid edge anomalies unless the edge is the decision surface.
• Photograph placements and scan device codes into CurNext so the physical world matches the digital association.

CurNext expects every live probe to belong to a project surface. Unassigned devices create noise and slow morning decisions.

RF and gateway staging for LoRaWAN jobsites

CN-CC uses LoRaWAN Class A (EU868 for certification SKUs). Wet decks, stacked rebar, and temporary works absorb and reflect RF.

• Stage gateways with line-of-sight to probe clusters whenever possible.
• Commission joins and acknowledgements before concrete arrives.
• Keep spare gateway capacity for multi-building pilots - the Helsinki-style layouts often need more than one coverage island.
• Use CurNext operations views to confirm last-seen and battery health instead of walking the slab blindly.

Battery, batches, and calibration lineage

CurNext tracks more than a MAC address. Device records connect to sensor batches, calibration certificates, and lifecycle status. That matters when an auditor asks which instrument produced a reading on a given day.

Li-SOCl2 packs are sized for long field life when duty cycles match the cure window. Do not "set and forget" without confirming:

1. Device identity scanned into the correct project.
2. Firmware and config template applied.
3. Calibration certificate current for the batch.
4. First telemetry visible in the CurNext dashboard within minutes of activation.

Commissioning checklist used by CurNext crews

1. Project and building selected in the dashboard or mobile workflow.
2. Surfaces prepared from BIM or manual structure.
3. Probe positions agreed and photographed.
4. Gateway online and covering the pour zone.
5. Devices associated to surfaces; readiness thresholds loaded where required.
6. Smoke test: temperature samples arriving, alerts routed to the right roles.
7. Handover note to the night shift: who owns heater or blanket escalation.

Common failure modes (and how CurNext surfaces them)

• Silent device: last-seen stale in fleet views - check RF path and power before blaming the mix.
• Wrong surface mapping: maturity looks fine but the wrong deck is celebrated - always verify room and surface labels.
• Late placement: probes dropped after vibration can migrate - place and secure before the pour.

Reliable installs are how CurNext earns trust. Treat commissioning as part of the pour plan, not an afterthought.
