PLATFORM

One platform to run an IoT operation — from device to dashboard.

KME Smart unifies real‑time monitoring, no‑code automations, device management, and dashboards under one MQTT-powered backbone. Built around the realities of running thousands of devices in the field.

Real‑time monitoring

Sub‑second telemetry from every device. Sparklines, live charts, alerts, and event streams that feel alive — not stale rows in a table.

P9542 ms

Device management

Provision, tag, group, and OTA‑update entire fleets from one pane. Built for the ESP32 ecosystem — ESP32, C3, S3, C6, ESP8266.

OTAstaged rollouts

No‑code automations

When → then rules with schedules, sensor triggers, geofences, and webhooks. Fan‑out to thousands of devices without writing a line of code.

Active1,284 rules

Live dashboards

Drag‑and‑drop tiles for every device class. Brand them in your colors, embed them, share with operators — 40+ widget types.

Widgets40+ types

INFRASTRUCTURE

Built on open protocols. Plays well with everything.

KME Smart bridges Wi‑Fi, Bluetooth, Zigbee, LoRa, and NB‑IoT into one unified message bus over MQTT. One REST API for everything else.

MQTT broker

Sub‑second pub/sub at scale

Every device speaks open MQTT. ACL‑gated topics, authenticated sessions, QoS levels for guaranteed delivery — backed by Mosquitto in production.

Open MQTT 3.1.1 / 5 — speak any client, any language
Wildcard subscriptions — fan‑in by site, room, device class
Retained messages — last known good state instantly

REST + WebSocket API

A modern API for everything else

Read live device state, fire automations, manage groups, push OTA updates, query reports — all from a clean REST surface. WebSocket for live streams.

JWT + device token auth — fine‑grained, audited
WebSocket streams — SSE‑style live events for browsers
