Ive got a Schlage zwave lock connected to the OPii. Unfortunately the lock lacks the ability to set codes which only work at specific times. I would like to be able to give a code to the housekeeper, but make sure it only works on certain days at certain times. I understand the lock has an API that permits the programming of codes via zwave--is is possible to script some code with haiku helper that adds and removes a code once a week on a schedule?
