When contact state is TRUE does that mean the contact (door the contact is on) is closed? 

When contact state is FALSE does that mean the contact (door the contact is on) is open?

What does contact "State Verified" mean?

If probably depends on the particular sensor/driver combo.   I know that a lot of drivers have an "invert sensor" option so, LOL, there doesn't seem to be universal agreement.

I think of True/On/Open as being synonyms and False/Off/Closed being synonyms.  I imagine a magnetic reed sensor as being a "closed" circuit when door is closed and the magnet pulls the reed to the wire,  completing (closing) the circuit.   But this mnemonic might be 180 degrees wrong.  In which case tick the invert sensor box!

I have always assumed that a verified state is one that is driven by a physical sensor and not just toggled via command.  So tracking a garage door based on the last command sent (open or closed) would not be a verified state.  But tracking state based on physical position sensor would be a verified state.
