Depends on how you want to do it. In neomodel, I think StructuredNode class instances have a ._id field. So if you have a node in memory, you can get its ID that way.

If you don't have a node that way, you can use cypher and the id() function:

neo4j-sh (?)$ CREATE (a:Foo {label: "Hello"}), (b:Foo {label: "Goodbye"});
+-------------------+
| No data returned. |
+-------------------+
Nodes created: 2
Properties set: 2
Labels added: 2

neo4j-sh (?)$ MATCH (f:Foo) return id(f);

| id(f) |

| 0     |
| 1     |
+-------+

Edit Access by ID:

MATCH (n) where id(n) = 1 return n;

MATCH (n) where id(n) IN [1,2] return n;
