The perfect IoT stack

Three parts, each doing what it does best — together, a complete low-code IoT solution.

IoT Platform

Connection & Sensing

Connect Arduino/ESP/Pi over MQTT & HTTP; capture and store telemetry reliably.

n8n

Actions & Alerts

Triggers → actions: notify, escalate, log, call AI and control devices back — no code.

Mobile Apps

Dashboard & Control

Live dashboards, two-way control and push alerts on iOS & Android — from anywhere.

Sense → Automate → Control. The platform senses, n8n decides and acts, and the apps keep you in control.

Everything you need, nothing you don't

A focused feature set designed for makers, teams and beginners.

Connect any device

Guided wizard with copy-paste code for ESP32, Arduino, Raspberry Pi, C++ & Python over MQTT or HTTP.

Two-way control

Buttons, switches & sliders write to virtual pins — control relays, motors & LEDs live, Blynk-style.

Low-code automations with n8n

Drag-and-drop flows react to device events — notify, control, log, or call AI with zero code.

Real-time dashboard

Live telemetry with auto-refresh, number cards, charts, gauges, LED indicators & maps.

MQTT & HTTP built in

A managed MQTT broker and a simple REST endpoint. Uplink telemetry and downlink commands.

Alerts & rules

Trigger on thresholds or device-offline, then hand off to an n8n flow for any action you can imagine.

Web & mobile app

Installable PWA — add IoTFlow to your phone's home screen and control devices on the go.

Self-hosted & open

Docker & Coolify-ready. Own your data and your automation engine, deploy anywhere in minutes.

From sensor to automation in three steps

Devices talk to the platform over MQTT/HTTP. The platform streams to your dashboard and forwards every event to n8n, where you build the logic.

1 · Connect

Flash the wizard snippet to your ESP32/Arduino/Pi. It streams data over MQTT or HTTP.

2 · Visualise & control

Compose a dashboard of charts, gauges, buttons & sliders — on web and mobile.

3 · Automate with n8n

Device events fire n8n flows that notify, control devices back, log data or call AI.
