One of the platform's key focuses is bringing device connectivity, dashboards, monitoring, analytics, and control into a single environment.

What Can You Build With KiwisIoT?

A typical project can look like:

Temperature Sensor
        ↓
      ESP32
        ↓
       MQTT
        ↓
    KiwisIoT
        ↓
