I have different window sensors for my doors and windows. Now I want to add a master sensor which displays me true if a door is open or false if every door is closed.
IMy idea was to add a dummy presence sensor and then a rule which says true if one of the doors/windows are opened or false if every door/window is closed. But how do i do this? or any better idea?
When device_plugin_zway_windowsensor15 is opened then set presence of device_dummypresencesensor present
this works only for the opening process after a second it changes the state
