This week we had the pleasure to record a 10-minute video session with Roger Light, the project lead of the Eclipse Mosquitto MQTT project. The goal of the session is to give a simple introduction to JSON and MQTT and how this two standards work together in IoT and Stream Processing. You will see that … Continue reading An introduction to JSON and MQTT with Roger Light
Streamsheets are a great tool to visualize and analyse real-time data that comes from event streaming platforms like MQTT or Kafka. In a previous post we showed how you can create real-time dashboards to display the current data of now (or just a few seconds or minutes ago). But how do you persistently store your … Continue reading Condition Monitoring with Streamsheets and MongoDB
In a previous blog posts I demonstrated how to set up a Streamsheet that controls a industrial machinery. I you haven't read this previous post you might consider reading it before continuing with this new post. In this blog post I will extend the Streamsheet application to serve as an analytical dashboard for the industrial … Continue reading Analytics, Dashboards and Predictive Maintenance with Streamsheets
In my previous post I showed how to connect industrial machinery with Streamsheets over MQTT to control a sorting process in real-time. I you haven't read the previous post you might consider reading it now. In this new post I will add an artificial intelligence based technology named Snips (http://www.snips.ai) to our use case. The … Continue reading Controlling Industrial Machinery with Snips AI and Streamsheets
Streamsheets can be used both in private environments (e.g. Smart Home) and in industrial environments (e.g. Smart Factory, Industrie 4.0, Industrial IoT). In this blog you find a 4 minute video that shows how to control an industrial machinery that sorts incoming parts according to its color and its shape. A MQTT Broker (www.mosquitto.org) is … Continue reading Connecting Streamsheets to Industrial Machinery via MQTT
In a previous blog I already introduced the Wi-Fi switch Shelly 1 (www.shelly.cloud). Basically this IoT-enabled switch allows to open or close a electrical circuit by sending the value "on" or "off" to a a predefined MQTT topic. The electrical circuit can then be used to control a electrical light or electrically operated machine. Another … Continue reading Snips, Shelly and Streamsheets
In the following 8 minute video you can see how to set up a Streamsheet that simulates a wind mill power plant and and publishes its data in real-time to a MQTT broker. Streamsheet with random number functions and a animated wind mill publishing data via MQTT There is not input stream for this Streamsheet. … Continue reading A Simulated Wind Power Plant as MQTT Publisher
