How Streamsheets work – Stream Processing and IoT for Non-Programmers

This blog post introduces the basic operation of Streamsheets. Using the example of a smart WiFi switch with an integrated power consumption meter (Shelly 2.5), we set up a complete Streamsheet use case within 10 minutes. This post contains 3 video sessions: In the first video just below you see how the data connection is … Continue reading How Streamsheets work – Stream Processing and IoT for Non-Programmers →

Wie Streamsheets funktionieren – Stream-Processing und IoT für Nicht-Programmierer

[There is an English version of this post available]. In diesem Blogbeitrag wird die grundsätzliche Funktionsweise von Streamsheets vorgestellt. Am Beispiel eines smarten WiFi Schalters mit Stromverbrauchs-Erfassung (Shelly 2.5) wird ein kompletter Streamsheet Use-Case aufgebaut. Dazu gehört ein Energie-Monitoring sowie eine automatische Abschaltung, wenn der Energieverbrauch oder die Betriebstemperatur zu hoch ist. (Falls Sie sich … Continue reading Wie Streamsheets funktionieren – Stream-Processing und IoT für Nicht-Programmierer →

An introduction to JSON and MQTT with Roger Light

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 →

Condition Monitoring with Streamsheets and MongoDB

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 →

Analytics, Dashboards and Predictive Maintenance with Streamsheets

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 →

Controlling Industrial Machinery with Snips AI and 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 →
