IoT ESP8266 Series: 3- ThingSpeak-Android Control NodeMCU's Ports Step 1: Circuit. To understand the uptime of the ESP8266 devices, the ESP8266 posts its uptime in one of the "Fields" to Thingspeak, allowing me to track the uptime of every box. My ESP8266 systems reliably run for 6 months or more, posting to Thingspeak every 5 minutes. You can see this in a screen capture of my simple channel, notice the ChannelID you will need that in your code later. Once done create a new channel and add one new field called temperature. You will now need to create a new account at thingspeak –. MQTT is a publish/subscribe communication protocol that uses TCP/IP sockets or WebSockets.
ThingSpeak enables clients to update and receive updates from channel feeds via the ThingSpeak MQTT broker. MQTT is a powerful standard for IoT systems. The ThingSpeak IoT service now supports MQTT subscriptions to receive instant updates when a ThingSpeak channel gets updated.ESP8266 NodeMCU with VS Code and PlatformIO: Upload Files to Filesystem (LittleFS) DecemESP8266 NodeMCU MQTT – Publish BME680 Temperature, Humidity, Pressure, and Gas Readings (Arduino IDE) December 19, 2020.A simple IoT test to control 8 channel relay using ESP8266 NodeMCU & aREST.io #newbie #simpLINnovation.On the hardware side, you required DTH11 connected to NodeMCU.
