Write Data to Channel
ThingSpeak™ is an IoT platform that uses channels to store data sent from apps or devices.
You can write data to your ThingSpeak channels in several ways: HTTP calls from the REST API, MQTT Publish method, and
the thingSpeakWrite function from MATLAB. Learn more
about how to Choose Between REST API and MQTT API to update a
channel.

Use Google Assistant to Turn a Light On and Off
Use your voice to set a channel value on ThingSpeak™. IFTTT interfaces directly with Google® Assistant to understand your speech and then write to a ThingSpeak channel.
Moisture Sensor Using HTTP POST Requests to Channel
Post multiple fields of data to a ThingSpeak™ channel from a device that wakes from deep sleep. You read a soil moisture sensor and post the value to a ThingSpeak channel. The HTTP POST request is executed by writing to a communication client without a separate library. Directly writing the HTTP request to the wireless network client can offer increased flexibility and speed over the ThingSpeak Communication Library.
Post Temperature Data and Read from Channel
Collect environmental data from a device and post it from your device to a ThingSpeak™ channel. The example uses an ESP8266 and the ThingSpeak Communication Library to post data and retrieve data from a channel.
