I have a Zen34 and it works good with the Edge Driver.
I am not sure what you have done to date. I would do the following:
- install the “Zooz Zen34 Remote Switch” Edge Driver from the link below.
- Exclude the Zen 34 right next to your hub.
- re-pair the zen34 right next to your hub.
- relocate the zen34 to where you want to use it.
