  • Provision Wi-Fi credentials via Bluetooth or softAP.
  • Securely connect to the RainMaker cloud using MQTT over TLS.
  • Create smart devices (switches, lights, sensors, motors) with a standardized JSON structure.
  • Support Over-the-Air (OTA) updates remotely.
  • Integrate with voice assistants like Alexa, Google Assistant, and Siri (via Apple HomeKit).

When you include #include <rmaker.h> in your sketch or source code, you are pulling in APIs for device creation, parameter reporting (like temperature or power consumption), and cloud synchronization.

Error 3: OTA or MQTT failures after compilation

  • Cause: You downloaded the ZIP but forgot to install the WiFiProv library.
  • Fix: Use the Arduino Library Manager to search and install "WiFiProv" (version 1.0.0 or higher).
