I have 6 windows with contact Sensors.
I have successfully created a rule when a window is open the dehumidifier turns off using a smart plug..
And turns on when the window is closed again..
Here is my problem..
There is 6 windows, so if i only close 1 window the dehumidifier will turn back on, but 5 other windows are still open!!
How do i make a rule so all windows have to be closed for the dehumidifier to turn on ?
So, after the install, you would create a contact group for those windows. Use the group device in your rule. The virtual device will show open when any window is open and only show closed when all windows are closed.
