Native iOS App Development
A Swift iOS application captures alarm audio, runs it through the shared decoder, and presents readable reports installers and homeowners can act on immediately.
EI Electronics, AudioLINK Smart Alarm Data Extraction
With Dev Centre House’s 14+ years of global product delivery, Dev House Australia built AudioLINK, a specialised app that listens to EI Electronics’ i-series alarms and converts acoustic events into clear reports on device health, battery life, sensor activity, and CO levels. Australian enterprises and startups in Sydney, Melbourne, and Brisbane trust Dev House Australia for the same delivery rigour.

About the client
EI Electronics manufactures advanced fire and carbon monoxide alarms for homes and professionals, with a focus on reliability, compliance, and connected insight. The i-series product line needed a companion experience that helps installers and homeowners understand what an alarm is reporting, without guesswork or manual logbooks.
AudioLINK closes that gap. The programme reflects connected-device engineering priorities: trusted event data, offline resilience, and software that must remain accurate when safety is on the line.
The challenge
EI Electronics needed software that could interpret alarm audio signals and translate them into structured event data, health checks, battery status, sensor triggers, and CO readings, reliably across real installation environments.
Field users cannot depend on constant connectivity; reports had to be generated and reviewed offline. Dev House Australia was asked to deliver native mobile apps with a shared sound-processing core for iOS and Android, maintaining parity in decoding accuracy and a straightforward UX for non-technical users.
The solution
Dev House Australia implemented AudioLINK as a cross-platform mobile programme with a Kotlin Multiplatform sound library at its centre, engineering for precision, auditability of decoded events, and offline-first use suited to IoT safety products.
Sound Processing Library
Kotlin Multiplatform powers the core sound-processing module, giving consistent interpretation logic on iOS and Android from a single maintained codebase.
Offline Capabilities
Sessions work without live network access, critical data is processed on-device and stored until sync is available, so surveys and maintenance visits stay productive.

Process followed
- 01
Discovery & Requirement Analysis
EI Electronics and Dev House Australia aligned on acoustic formats, report fields, offline workflows, and App Store compliance for a safety-critical audience.
- 02
Development
Swift UI and Android clients were built around the shared Kotlin Multiplatform library, with iterative validation against live alarm samples.
- 03
Offline Functionality
Local storage and processing paths were tested in low-connectivity scenarios to ensure reports remain available when networks do not.
- 04
Testing & Deployment
QA covered decoding accuracy, regression on OS updates, and store submission requirements before public release.
- 05
Feedback & Iteration
Post-launch feedback informed tuning of decoding thresholds, report clarity, and performance on older devices.

Outcome results
Installers and homeowners receive clearer visibility into alarm health, power status, and CO-related events, reducing callbacks and improving confidence in i-series deployments. Offline operation keeps field workflows practical across rural and urban sites alike.
Shared sound logic across iOS and Android lowers long-term maintenance cost while preserving consistent results. For Australian organisations building IoT and safety technology around verifiable device events, this engagement shows how Dev House Australia delivers from discovery through store release, with support for teams in Sydney, Melbourne, Brisbane, and nationwide.
