description: >-
  ThingSpeak is an IoT analytics platform from MathWorks that lets devices aggregate, visualize, and analyze live data
  streams in the cloud. Devices push telemetry to channels via a REST update endpoint or the `mqtt3.thingspeak.com` MQTT
  broker, and the platform layers in MATLAB Analysis for compute, MATLAB Visualizations for plotting, React for rules,
  TalkBack for cloud-to-device commands, ThingHTTP for outbound webhooks, and TimeControl for scheduling. ThingSpeak is
  the only mainstream IoT platform with first-class MATLAB and Simulink integration, making it widely used in academic
  research, environmental monitoring, smart agriculture, and energy applications. Compatible with Arduino,
  ESP8266/ESP32, Raspberry Pi, Particle, LoRaWAN gateways, and industrial controllers.
