Thanks to the very active ThingSpeak community, we have been able to make some updates to the open source ThingSpeak API and web app. We also have a major new release coming. The latest updates allow ThingSpeak to be installed without dependency on the Internet. This means you can run this on an embedded web server with no Internet connection. This is perfect for when you want to log sensor data behind a firewall and build apps that do not require (or have) remote connectivity.
All of the latest code is available on GitHub, so start building your own Internet of Things today!
