IoT automation with EVA ICS
EVA SFA controller hosts “ui/” folder as static web content (except .j2 files), but you can perform a little trick on YAML and JSON files: convert them on the flow.
E.g. you have YAML file “config/test.yml” with content:
param1: 1 param2: somevalue
to get it as JSON, add “as=json” param to query string:

To test and demonstrate this feature, we’ve made PHIs for 2 popular LED controllers: Philips HUE and Nanoleaf. Everyone likes playing with LEDs, even industrial guys )
Both PHIs can be found at EVA ICS website and downloaded to Universal Controller instance.

Weak security is a major problem of almost all modern IoT and IIoT/Industry 4.0 solutions. There’s usually nothing wrong when equipment state or shadow state is available for nodes in your configuration, as one of Industry 4.0 design principles is “Information transparency”.
However things change when we start talking about control. Allowing nodes to control each other and send action API calls is dangerous: if attacker get an access to information exchange point, he can destroy your business or even your life.
