Built on real IoT, end to end
ESP32-based hardware, a secure MQTT cloud, RFID attendance, and over-the-air firmware updates — all in one connected platform we design, build, and support ourselves.

Hardware designed in-house
Every device runs on ESP32 firmware we write ourselves, connects over MQTT, and updates over the air — turnkey from power-on.
Display + Notice BoardSmart Display Clock
A versatile ESP32-powered display that shows synchronized time by default and transforms into a notice board, timer, or stopwatch on command.

What the platform actually does
A complete, connected operating system for your devices — not just a dashboard bolted onto hardware.
Dynamic notice board
Switch any clock to notice mode. Broadcast to a single device, a group, or the whole site — instantly or on a schedule.
RFID attendance capture
Card taps stream to the dashboard in real time. Admins can manually correct any record via the web.
Centralized dashboard
One source of truth: live records, device configuration, attendance analytics, and notice scheduling — all in one web UI.
OTA firmware updates
Push new firmware from the dashboard over MQTT. Devices download, install, and report progress back over the air.
Real-time device monitoring
Online/offline status, free-heap telemetry, last-seen heartbeats, and latency — visible the moment it changes.
Scheduled notices & timers
Set notices and countdown timers with precise start/end times, handled reliably by a server-side job queue.
Role-based access control
Superadmin, admin, and user roles — each sees and manages only the devices and groups they're permitted to.
Secure MQTT transport
TLS-encrypted broker with username/password auth and QoS 1 delivery for stable, guaranteed message handling.
The architecture, simplified
A proven IoT stack — from the microcontroller on the wall to the dashboard in your browser.

Power on & auto-provision
An ESP32 device boots, joins WiFi, and publishes its first status to the MQTT broker — the server auto-registers it. No VPNs, no port-forwarding, no manual setup.
Secure MQTT publish/subscribe
Device and server talk over TLS-encrypted MQTT (QoS 1). Attendance taps, status heartbeats, and mode changes flow in real time; notices and OTA commands flow back.
Dashboard, alerts & OTA
The web dashboard and Socket.io push live updates to admins. Firmware updates are delivered as a signed download URL the device fetches and installs over the air.
Who it's for
Built first for education, flexible enough for anywhere people, time, and notices need to connect.
Education
Schools, colleges and universities — automated per-class attendance, instant notice broadcasts, and exam timers across every room.
Offices & workplaces
Staff time-tracking, meeting-room signage, and company-wide announcements pushed to displays at every desk and lobby.
Manufacturing
Shift attendance, safety notices, and countdown timers on the production floor — with audit-grade attendance records.
Healthcare
Staff attendance plus critical alert displays in clinics and wards, where a missed notice can matter.
Retail
Staff coordination, shift announcements, and promotional notice boards across store locations.

Average payback period
Don't see your device? We'll build it.
Beyond clocks and attendance terminals, we design new IoT hardware to your exact specification — from one-off prototypes to full deployments.
Requirements
We dig into your use case — what to sense, display, and control — and scope the right hardware + firmware.
Prototype
We build a working prototype: custom ESP32 firmware, sensors, enclosure, and cloud integration.
Pilot
A small batch runs in your real environment. We refine based on the feedback and the data.
Scale
We manufacture, provision, and roll out the full fleet — with OTA updates for life.
