Commercial Proof
References that show how Combotto turns IoT audit pressure into a scoped path forward
These case studies are not a project archive. They show the kinds of systems, risks, and delivery outcomes Combotto is brought in to clarify before launch, customer scrutiny, or scaling pain gets more expensive.

STM32 SCD4x CO2 Sensor Indoor Air Quality Case Study: MQTT and I2C IntegrationIndoor Climate Field Proof
Engineering case study of integrating an SCD4x CO2 sensor with an STM32 B-L475E-IOT01A2 over I2C, publishing CO2, temperature, and humidity through MQTT with live room-state visibility and configurable CO2 alarms.
Indoor climate CO2 proof
Then inspect how an STM32 device, MQTT path, and monitor alarm flow stay legible for indoor air quality and CO2 use cases.

Shows the system under pressure, the evidence surfaced, and how Combotto turned that into a practical next move.
Open case study Rust IoT Gateway Hardening Case Study: From Plaintext Ingest to Verified TLSAudit -> Sprint -> Retainer Case Study
How a before-hardening audit exposed four gateway and ingest findings, a focused sprint fixed them, and the after-hardening check created a clear reference point for ongoing review.
Audit -> Sprint -> Retainer proof
Start here for the clearest end-to-end example of one gateway slice audited, hardened, and rechecked.

Open case study How To Read The Proof
Use the newest proof first, then use the helper notes below to decide which audit slice matches your pressure.
The library above is date-driven. These helper notes exist so a buyer, partner, or internal stakeholder can quickly choose between the end-to-end hardening case, the broader gateway audit, and the field-proof monitoring slice.
Customer scrutiny
Start with the audit and hardening references if a buyer, partner, or internal stakeholder needs a clearer answer on security and operational risk.
Launch pressure
Use the gateway-focused cases when production is close and hidden path, transport, or telemetry gaps need to be surfaced fast.
Reliability drift
Finish with the fleet-monitoring proof when the system works in pieces but the evidence trail still feels too weak for confident follow-through.
