The gist I get is that it's a daemon for a gateway device (like a Raspberry Pi) that you configure data flows via JSON files. The Flogo CLI seems to be a JSON generator (https://github.com/TIBCOSoftware/flogo-cli/blob/master/READM...). They compare their functionality to Nodered (http://nodered.org/) except it doesn't have a GUI (they mention working on it) and instead of being written in Node.js, it's written in Go.
I'm of the opinion that these frameworks for Gateway devices are reinventing Unix pipe and cron, that integrations for devices and databases should be written in any language (as CLI), and running logic on the gateway is 90% of the time not what you want to do, you just want to pull data from a device and push it to a database somewhere. Shameless plug, in my free time I work on Open Pipe Kit, a project that is building CLI for devices and databases. We're currently working on a series of DIY LORA Nodes for Agriculture.
