Having just got V_ARMED working as I want I notice that when a node presents itself and children that the V_ARMED setting seems to be disabled by default.
So a node with child sensor V_TRIPPED and V_ARMED will only display V_TRIPPED as default. You have to go through the menus to enable V_ARMED and that could be an issue for many people who are new to this.
Once found and enabled though, it does do what I want
@hoegaarden_bier MyController searching in the database for that gateway from 1-254, will give first available id.
@danilosouto You mean dashboard widgets update time? For dashboard we can configure refresh time. Sensor action default refresh time 30 seconds. you can change this under Setting-->System--> global page refresh
