This thread will remain for support of 3.4 installations.See WizLighting Binding [4.0.0,) for OH 4.x support going forward.
Note that I have added supported OH version specifications to each marketplace thread, this should show the correct binding version compatible with the OH version you are running.
I have tested the version released in the 4.x thread above against a 4.0.1 fresh installation and it worked perfectly, it is now available to install via the new thread in the marketplace add-ons section. Hopefully this helps straighten things out and welcome to OH 4! (sorry for the delays)
Thanks,
