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.
