I ordered at digitec on 17.11.2019 and it shows Hardware version: 3.0 in the WebUI.

When placing a new order you should receive the latest version, which is the 3.0 version.

This version I received, and that about one year ago, supports the Omada Controller, as I have 2 of them and one outdoor version. The only thus they do not support which I thought they would is Mesh, which would be handy when no cable connection is available.
Hope this helps
