There has been quite a lot of IoT automation / rule engine stuff done in NoFlo in the last couple of companies I’ve worked at, but obviously I can’t really go into specifics there.

On the front-end side, Flowhub uses NoFlo for state management, a bit similarly to how you’d use Redux: https://github.com/noflo/noflo-ui
