Remote Lockbox Answered
I would like to build a small lockbox to which I could remotely provide access. For example, I leave the box at a property. At a later date, an employee is in the area and we would like him to access the property without having to make a trip back to the home office to pickup the keys. We provide him a one-time access code and he retrieves the key.
I recently discovered how much fun Raspberry Pi DIY projects are and this seems like an ideal candidate for my next challenge but I have to confess I am still a total neophyte to all this with no real notion as to the best way to move forward. I would welcome any suggestions or ideas. I also realize my definition of the problem might be more vague than is ideal but given my lack of confidence vis-a-vis which details are relevant, I thought it would be more productive for me to answer questions rather than post a giant wall of useless information - which is my long-winded way of saying, please do not hesitate to ask me any questions if they'll help get me pointed in the right direction.
