Learn how to publish and subscribe to messages sent via an MQTT message broker to be able to remotely control or monitor the status of devices, including Arduino, Raspberry Pi, Android, PC, and Wemos D1. In this video I'll demonstrate how to install and setup the Mosquitto MQTT server, available at www.mosquitto.org, on a Windows PC. I'll then create clients that subscribe to topics on that MQTT broker running on an Arduino UNO (via an Ethernet shield), a WeMos D1 (connected via built-in Wi-Fi), and a Raspberry Pi (connected via built-in ethernet), and control those devices by publishing messages using a command-line PC application and an Android app. You can access the wiring diagram, additional documentation, and code downloads used in this video at https://www.patreon.com/posts/17921563 00:00 - 05:55 Introduction and Demonstration 05:56 - 07:34 Android client demonstration 07:35 - 13:03 Arduino, Wemos, and Raspberry Pi Wiring 13:04 - 20:01 Installing and testing the Mosquitto MQTT server 20:02 - 37:24 Code for Arduino Ethernet and MQTT client 37:25 - 43:05 Code for Wemos WiFi and MQTT client 43:06 - 48:33 Code for Raspberry Pi MQTT client 48:34 - 50:10 Android client (MQTT Dash) 50:11 - 51:12 Wrapup

MQTT for IoT
 
03:39
This video shows a simple application where 4 devices communicate usgin MQTT. The devices are: 2 Raspberry PI's, one Windows desktop PC and an Android phone. One of the 2 RPi's have one temperature and humidity sensor attached, the other one is set as MQTT broker and it also has a PI Face 2 DI/DO interface. The Windows and the android app are subscribed to the RPi temp and humidity reading so the broker get those reading from the second RPi and send them to the clients subscribing to those "topics"; they can also send commands to the PI face DO and red back the DI status. All devices are coded with B4x with some phyton scripting "help" for the temp and humidity reading.

Yo, In this video, I'll be covering how-to install, setup, and use Mosquitto MQTT broker on a Raspberry Pi. Mosquitto is an awesome open source MQTT broker that you can run on a device like a Raspberry Pi. It's great because you don't have to share you data to the cloud and can keep everything locally on your system. Plus, it's free! MQTT is a great protocol for various DIY tech - like an Arduino, NodeMCU, or ESP8266 chip. If you have any questions, let me know! Happy to help with what I can!

My IoT socekt made using Esp8266, JSON over MQTT, mosquito broker and websockets. The ESP-01 is accepting JSON over MQTT from my mosquitto broker. To control the socket from my phone, I've created an android application that connects over websockets to mosquitto broker and is sending commands. Plug is sending status every 15 seconds to its subscribers and a status after every command its receiving. Cool.....now I can turn on or off my favorite lamp with my IoT device http://myesp8266.blogspot.ro/2015/04/first-iot-device.html

Internet of Things - Why You Need MQTT
 
04:42
Today I will talk about what MQTT is and why you need it in your solutions for the Internet of Things. After a comparison with HTTP, I will go through how MQTT works and what benefits it brings. With the Internet surviving for such a long time using the HTTP protocol, you might ask yourself why you would ever need another protocol. Well, HTTP is great for doing a request and getting a response, like when a client want to ask a server for some information, and get an answer back. But it doesn't really have a good solution when a source of information should push a change to many clients, and there is no built-in support for quality of service. The text-based format of HTTP requires more bandwidth, and any device that wants to act as a host needs to have a web server installed. Keeping a web server alive to answer incoming requests takes a lot of battery power, which is a scares resource on any "thing". So, let me introduce the Message Queuing Telemetry Transport (MQTT), which is a protocol that can solve many of these problems. First of all it uses a publish-subscribe messaging pattern, which means that any source of information (such as a sensor) can publish its data, and then any client can subscribe to that data. All this is happening in a broker that keeps track of all publications and subscriptions, so when a publisher sends an update with new data (publish a message), the broker takes care of sending the new data to all subscribers. The built-in support for quality of service means that the broker can guarantee delivery of a message, e.g. that it's delivered at least one time or exactly once. MQTT is a binary format that requires a minimum of bandwidth (the fixed header is only two bytes), and it also has a small implementation footprint that require less battery. Both of these efficient aspects can make MQTT scale very well, and that is important when we are talking about millions of "things". It's not as established as HTTP, but it's standardized by OASIS and backed by IBM. To see how it works, let's set up an MQTT broker, and I have selected mosquitto, which is the most famous open source MQTT broker. I will set it up on a cloud server with Ubuntu (12.04 LTS), and to get one of your own, please see my video "Omnichannel Services – Cloud Server". Start by connecting to the server (replace AwsKeyPar.pem with your key file, and 0.0.0.0 with the IP address of your server)... ssh -i AwsKeyPair.pem [email protected] ...and then install and run mosquitto using the following commands: sudo apt-add-repository ppa:mosquitto-dev/mosquitto-ppa sudo apt-get update sudo apt-get install mosquitto sudo apt-get install mosquitto-clients mosquitto Now open a new terminal window, connect to the server (see ssh command above) and enter the command: mosquitto_sub -d -t hello/world This starts a subscription to the topic "hello/world". Now open yet another terminal window, connect to the server, and enter the command: mosquitto_pub -d -t hello/world -m "This is my first message" This will publish a first message on the topic "hello/world", and it should appear in the second terminal windows where you set up the subscription. So there you have your mosquitto MQTT broker running. With that I hope you understand what MQTT is and why you need it to build efficient and scalable solutions for the Internet of Things.

Using the Sonoff IoT/WiFi Relay with your own MQTT Server (#52)
 
12:35
Previously I connected up a Sonoff relay (about £4 to buy) to my WiFi, to switch mains loads via a phone app. What I really want, though, is to reflash the unit so that it works with a server here in the house rather than the Sonoff/eWelink server up in the cloud. Using the same method I could talk to my own cloud server, using Amazon Web Services or Google Cloud. I'm using the Tasmota software in my Sonoff relay, an awesome piece of work from Theo Arends: https://github.com/arendst/Sonoff-Tasmota There's a very nice walk-through of how to build Tasmota (using PlatformIO and the Atom editor) on the QuickPi channel: https://www.youtube.com/watch?v=n4MDRm2yAJg His walk through is on a Mac, but the Atom/PlatformIO works exactly the same on Windows, and this is what I did.

Live monitoring your sensor's value from anywhere in the world using ESP8266 and Adafruit MQTT
 
12:32
In this video I have shown how to monitor your sensor's data on your smart phone from anywhere in the world. The concept used for this project is, I used the most popular board for iot related projects ESP8266. Now as we know that most of the sensors existing in the market gives us output in analog form, so I opted for esp8266 12e development board instead of esp8266 01 as the esp8266 01 module doesn't have analog pin while esp 12e has 1 analog pin in it. After that I have used 14.7 mm Force Sensitive Resistor(FSR) for explaining the concept but you can use any sensor. So whenever the sensor is pressed the varying voltage value will be appearing at analog pin 0 of our esp board and the esp board will publish that reading on Adafruit IO server through MQTT protocol. And on the smart phone side,we need to install an app called IoT MQTT Dashboard from Google playstore. _________________________________________________________________ Adafruit MQTT Library - https://github.com/techiesms/Adafruit_MQTT_Library _________________________________________________________________ Buy the components from here ESP8266 12e Board - http://amzn.to/2gCd3ad Force Sensitive Resistor - http://amzn.to/2w1j2eg _________________________________________________________________ Facebook :- http://www.facebook.com/techiesms Twitter :- http://www.twitter.com/imtechiesms Website :- http://www.techiesms.com _________________________________________________________________ #techiesms explore | learn | share

What is Paho? In the Maori language, paho means "broadcast, make widely known, announce" -- and in this talk, Andy would like to make sure that more people get to know about Paho, a very cool messaging protocol contributed to the Eclipse Foundation by IBM and Eurotech. Paho is an implementation of MQTT -- a lightweight, scalable, messaging system for connected devices and the Internet of Things. Andy looks at the protocol, some example code, how Paho relates to other projects, and talks about interoperability with other Java-based MQTT-capable brokers like HiveMQ and ActiveMQ (and maybe some non-Java ones as well...).

LinuxCNC controlled by Android
 
01:57
This is a first working test of a remote LinuxCNC UI running on supported Qt platforms like Android, iOS, Linux, Windows, .. The final goal is to be able to run a full LinuxCNC control including stepperdrives on $50 worth of hardware, namely a cheap Cortex-A8 computer such as Raspberry Pi Zero, Raspberry CM1, i.MX51/AM335x-based hardware, etcetera. Just because we can. Another nice application is the ability to use this as a secondary UI screen. Now, how does this work? On the LinuxCNC side there is a server process that connects to the LinuxCNC Python interface. This process translates the error, status and command channels to JSON data which is posted/read to an MQTT broker over a secure socket. The client also connects to the broker over a secure websocket, and the two parties are able to exchange status and commands. Advantage of this approach over a pure socket is that the broker can be anywhere, and so can the clients. Thus, it also works flawless on a phone using a 3G/4G connection. Also, MQTT provides basic quality of service, it is lightweight and fast, you can have as many UI's running as needed. It is also very easy to enhance functionality by designating different MQTT topics for different functionality. A separate webcam server process on the LinuxCNC machine could dump image data to a /webcam topic, and on the client side a separate viewer can extract this information without interfering with a webcam-unaware GUI. Please forgive the crude layout, my experience with Qt is only a few hours.

Internet-of-things via MQTT on Cosino
 
00:39
In this example of Internet-of-Things (IoT) application a Cosino with the Mega 2560 extension is used: the Mega 2560 CPU drives a led and is interfaced to the popular DHT22 humidity and temperature sensor. On the Linux side a software is running that reads the status of the sensor and sends data through the MQTT protocol to a demo broker available at http://www.mqtt.io/. Collected data can be accessed anywhere with a web browser. Therefore, a web panel interface was built to turn on/off the LED and to show the status of the DHT22 sensor.

Internet of Things - Control Sensors
 
05:49
Today I will talk about how you can publish sensor data depending on a threshold and control a sensor using an MQTT broker. I will publish information to the MQTT broker about the light depending on a threshold, and also show how the threshold can be changed using a subscription on the MQTT broker. In my previous video, I was publishing light and temperature data to an MQTT broker at a fixed time interval (every 5 seconds). However, in most Internet of Things solutions it's more interesting to know when a threshold value has been passed or when an interval has been exceeded. A real-world example is a wine cellar, which need to keep the wine in a certain temperature interval (usually 7-18°C or 45-64°F), and the important thing is not to know the exact temperature, but if the temperature goes outside of that interval. In this lab I will show you how to implement the logic of a threshold value, and also how that value could be changed using an MQTT broker. This means that the behavior of the sensor can be changed remotely, and this is a very powerful feature of any Internet of Things solution. I will use a light sensor to determine whether it's dark or light, and then act on that. When it's dark a LED will be turned on, and when it's light the LED will be turned off. As you can see in my video "Internet of Things – Like Lamp", the LED could be replaced with a normal lamp. A real-world example would be a welcoming light in front of the house or office that is turned on when it's dark (at night or due to bad weather). Here you can see the needed hardware, and in addition to the Arduino, you need a light sensor, or photocell, a LED, a 220 ohm resistor, and to connect everything, you need a breadboard and five jumper cables that have a (male) pin on each end. To setup the hardware, you start by disconnecting everything from its power source, as usual. Then you connect the sensor to the breadboard, and the Arduino 5V to the power (plus) on the sensor. Connect the Arduino ground (GND) to the ground (minus) on the breadboard, and then connect the breadboard ground to the sensor ground. Connect the sensor signal (S) to the first analog pin (A0), and connect the Arduino pin 13 to the positive (long) end of the LED. Connect the negative (short) end of the LED to the resistor that in turn connects to the breadboard ground. The Arduino code (or sketch, which you can find on http://cforsberg.com/?p=177) starts with some includes, and define the constants for the pins (on line 4). The MQTT client object is defined and created (on lines 5-6), followed by the declaration of a number of variables (on line 7-10). In the setup, we set the LED pin to output (on line 14), and initialize the bridge between the microcontroller and the microprocessor (on line 15). Then we connect to the MQTT broker and set up a subscription (on line 16). The eternal loop starts by checking if a one second interval has passed, and if so, read the value from the light sensor (on line 24), check if the value has passed the threshold (on line 25), and if so, publish the new status to the MQTT broker (on lines 27-31). In the callback function, which is called each time a new value is published on the topic that was subscribed to, the message (payload) is read (on line 39-41) and parsed (on line 42), and the new threshold is updated (on line 43). I'm assuming that you have an MQTT broker running (see my previous video called "Internet of Things – Why You Need MQTT" to see how the server can be set up and how to start the MQTT broker), and to see the published data, connect to the server (replace AwsKeyPar.pem with your key file, and 0.0.0.0 with the IP address of your server)... ssh -i AwsKeyPair.pem [email protected] ...and then run the command: mosquitto_sub -d -t lightsensor/value This starts a subscription to the topic "lightsensor/value" where you can see the published sensor data. To change the threshold, open a new terminal window, connect to the server (using the same ssh command above), and run the command... mosquitto_pub -d -t lightsensor/control -m "{\"value\":300}" ...that will publish a message on the MQTT broker that will be picked up by the Arduino, which will use this value as the new threshold. That is how you can publish sensor data depending on a threshold and also control the sensor by updating the threshold using an MQTT broker.

WebSocket + mqtt
 
00:15
The video shows an open source and cheaper example of Internet of Things (IoT) application: two LEDs controlled by two ESP8266 WiFi modules (the clients), connected with a Raspberry (the broker) using #mqtt protocol; the #Raspberry is also configured as #WebSocket server using Node JS for handling real-time communication between devices such as PCs, tablets and smartphones. In the video, smartphone uses VPN connection, while the others are connected with 802.11. The shell on the left top shows the console notification: object status, connected clients, commands sends and feedback. Obviously, LEDs are only a simple example: ESP modules can be used to control lights, blinds, garage doors, air conditioners or whatever you want.
