Super useful tool which allows you to make every system on your network reachable via protocols such as MQTT. Now you can distribute tasks to other systems, and interact with each other based on certain events.
Unfortunately, it looks like the most recent dev suddently dropped all interested, and has shut down the forums, and isn't responding to requests from people willing to take the project over.
There's no replacement for this application with such flexibility and small footprint.
The good news is, you can download the latest official files here, and the software is 99.9% functional/stable on Windows 10.
