Read the stor...

The MATLAB AI Chat Playground was launched on the MATLAB Central community at the end of November. I recently got the chance the interview the chatbot about ThingSpeak. I was curious how much it knew about building IoT projects on ThingSpeak and data analysis with MATLAB. Here are some excerpts fro...

If you want to upgrade your ThingSpeak capabilities, have a look at the ThingSpeak repository of template codes that open in MATLAB Online. ThingSpeak has MATLAB built in to make it easy to analyze and visualize your data, but the text window for MATLAB analysis and MATLAB visualizations can be tri...

Professor Chao Wang at Arizona State University recently introduced a course on AI and IoT to first-year engineering students. Deep learning in MATLAB is used to classify images and send the results to ThingSpeak in the cloud. ThingSpeak allows the class to aggregate the results and compare their w...

Many users have asked, and it's finally here: Your devices can upload images to ThingSpeak! With this new feature, you can create a cloud-based tracking or monitoring system for your important assets by taking photos and uploading them to ThingSpeak image channels. Users with a paid ThingSpeak ...

Starting with iOS 14, Apple introduced widgets for the iPhone and iPad. Widgets elevate information to the top of your device and offer information at a glance. They help you customize your device in new ways. Wouldn't it be awesome to have a ThingSpeak widget on your iPhone? Thanks to a new app...

ThingSpeak has released an update to the MQTT service that improves access control and device management for IoT projects. This new interface is available to all ThingSpeak users. Learn more in the ThingSpeak Doc. If you have used ThingSpeak MQTT in the past, I wanted to mention one big change to h...

We were searching around for ThingSpeak IoT resources and noticed that Google was sharing the top questions related to ThingSpeak. Christopher Stapels and I thought that it would be fun to answer them and share them as a blog post. So, here we are. How do you use ThingSpeak? Some people use ThingSpe...

This time of year is about staying connected, maybe more so this year than with previous years. CheerLights is an IoT project to share some of the connections through synchronized lights. All of the lights connected to the CheerLights feed hosted on ThingSpeak stay in sync. The lights all shine with...

ThingSpeak automatically gives you access to the latest MATLAB features from the latest MATLAB release. MATLAB R2020b now includes swarmchart to create sarm scatter charts! The charts are a great way to visualize many measurements across a limited number of categories. Here is a swarm chart of wind ...

ThingSpeak users frequently ask how to build customized views for their ThingSpeak data. The channel view provides automatically generated field plots that are customizable with the ThingSpeak Charts API or a MATLAB visualization. You might want to run prepackaged analysis repeatedly or based on a v...
