+      `result` shows the result of the last fingerprint reading and can have the following values:

+      `key id` is an id number. For the fingerprint sensor, it can also be `administrator` or `unknown operator`
+  - property: lock
+    note: The state of the lock depends on the last `action`. The lock entity has five extra attributes, `action`, `method`, `error` and `key id` and `timestamp`
+  - property: action
