Most of these examples are using the automation integration and other built-in automation related and organization integrations available. For the test, MQTTlens was subscribing the "esp/test" topic before connecting the ESP8266. ThingSpeak is an IoT analytics platform service that allows you to aggregate, visualize, and analyze live data streams in the cloud. DHT11 Pin = Pin 2 (GPIO2 of ESP8266 ESP-01) Sound Pin = Pin 3 (GPIO3 of ESP8266 ESP-01) Relay Pin = Pin 1 (GPIO1 of ESP8266 ESP-01) Since we are going to send data to the Cayenne IoT platform using MQTT API, we need to pass the sensor value to the virtual pins. As it happens I was using python 3 in my first test. Specifically vs DDS, MQTT is a lot simpler and easier for a normal person to understand ("ok now send a structure with a command name and a payload string" should sound familiar to everyone, I think), and it works over TCP, making it potentially more network-friendly than the UDP-based DDS.

This will disable the relay from returning to the same state after power on UNLESS you use the MQTT retain flag in which case the MQTT broker will send the last known MQTT state on restart or power on. If these devices are creating constant streams of data, then this creates a significant amount of data. Variation on my other thread. For an example see line 126 on this link using bot. Introduction: MQTT is a very popular IOT protocol which allows different devices to communicate through internet. Once the instruction (say “turn on” for instance) is received over MQTT, the NodeMCU matches it with corresponding IR signals and the signal is sent to the AC through an IR led. Hillar for free with a 30 day free trial. However, in some scenarios you cannot easily map the data your devices send into the relatively small device-to-cloud messages that IoT Hub accepts.
