I have installed two HRDS-1s as garage door sensors, and two Evolve FM-20 relays to activate the door openers. I operate the doors with a scene containing a Luup script that checks the sensors state (using variable_get for Tripped) combined with an advanced scene setup that activates the relay for 2 seconds. The opening and closing works fine, only opening the door if the Luup detects that the sensor shows it to be closed, and vice versa. The problem I am having is that in the UI4 interface, the sensors show the red running icon when they are actually not tripped, even though the scene works. When I look at the Advanced tab of the sensor, it shows the Tripped variable to be 0 even though the icon shows red.
My question: what does the red icon in UI4 truly represent, if it does not represent the Tripped state of the sensor?
