Lock Entity	Lock

A lock entity is a device which is able to lock and unlock. Locking and unlocking can optionally be secured with a user code. Some locks also allow for opening of latches, this may also be secured with a user code.

Properties

Properties should always only return information from memory and not do I/O (like network requests). Implement update() or async_update() to fetch data.

changed_by	string	None	Describes what the last change was triggered by.
