Another one of those what the heck is the correct term for this as my google foo has failed again.
I'm currently looking at setting up electronic door locking system the the common door lock types are Fail Safe(Most Common)/Fail Secure however what I'm wanting is something in between
The idea being that if the UPS starts feeding from the battery it tells a Raspberry Pi, the Raspberry Pi then checks its calendar and then programmatically set the lock to lock if it's a defined Fail Secure time or unlocked if in a Fail Safe time so that if the power outage lasts longer than the UPS can supply it keeps that state however none of the locks I can find do this and googling terms that make sense for this type of configuration returns nothing of use.
I guess I could take one of the Fail Safe door bolts and remove the cap that must power it during a outage or unlocking but that feels like a lot of work and may cause some other issues. surely I cannot be the only one who needs this type of lock.
