Extended unit state in PHIs. Playing with LEDs

New Driver API v5 in EVA ICS 3.2.2 brings important improvement: now Physical Interface modules can support extended unit state (status + value). 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 )

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.
