ThingSpeak™ is an IoT platform that uses channels to store data sent from apps or devices.
You can read data from your ThingSpeak channels using the HTTP calls and the REST API. You can use the MQTT subscribe
method to receive messages whenever the channel is updated. And you can use thingSpeakRead
to read data from your channel in desktop MATLAB. Learn more about
when to Choose Between REST API and MQTT API to update a
