Hi! Ex-Smartthings user here 
I'm attempting to set up a virtual 3 way with direct associations between Zooz ZEN72 dimmers on my C7 hub using the advanced dimmer driver from jtp10181.
When I have the association set up it is laggy and sometimes ceases to work.
I then looked at the debugging logs and noticed that upon simply trying to change the dim level on the remote switch this was happening:
Hallway light: level was set to 82% (digital)
Hallway light: switch was turned on (digital) [NOT CHANGED]
Hallway light: level was set to 96% (digital)
Hallway light: switch was turned on (digital) [NOT CHANGED]
Hallway light: level was set to 98% (digital)
Hallway light: switch was turned on (digital) [NOT CHANGED]
Hallway light: level was set to 100% (digital) [NOT CHANGED]
Then when I decided "Lets see what happens if I unplug the hub"- It works flawlessly!!!
Anyone faced this before?
Those logs would be the main switch reporting status changes back to the hub. This seems normal to me, this way on any dashboard you have you can see the current level it is set to. From there the hub should take no further action besides logging the event, unless you have setup rules or other mirroring on the hub. Do you have anything that is redundant to the associations setup on the hub that might be causing duplicate messages when the hub is powered up?
It might be helpful to post your settings from both devices, including the association settings. Also indicate which one is connected to the light and which one has no load.
Side note - unless it is very important that your extra no-load switch works when the hub is offline, you might actually be better off creating a virtual association on the hub itself (built in mirroring app). I have seen other cases where people found better results with that vs the direct device associations.

Thank you for the quick response! Good to know the logs look as expected.
That's the odd thing though- there are no other automations or anything! This is a fresh (up-to-date) hub and new switches (v10.0). No apps, nothing.
The on/off works fine but dimming throws it all off. Even if I switch back to the OEM drivers.
Both switches are set the same way- all defaults minus the association IDs. This happens with both associated or only one-way.

P.S. The pending change is Attribute #7 going from null to 15
Yes I was recently made aware that the ZEN71/72 do not support param #7 so in the next driver version it will be removed for those models. I should be pushing it out this weekend I hope.
I have a ZEN77 in action but not a ZEN72 yet (still in box). Let me read the docs on it, might be some settings that will optimize it.
Do you have an association setup on both devices to link them together or only on the "remote" switch pointing to the control switch?
I actually have 77s that I had not set up yet. I just tried them and they actually work!
Sorry forgot the last part- in either case same outcome. Whether they are linked together or just remote to load.
I dont know why it would be having issues when the hub is running. I would try setting up the mirror app on hubitat and remove the associations, see how that works.
I am not an association expert at all but I just wanted to note that I have two separate pairs of zen76 with a simple association working without any issues.
I set this up originally when both pairs were zen26s and I was getting wired “flash-on” behaviour when handlind things in the hub. There is something weird with the zen26 that it does not like receiving commands from the hub right after a single upper paddle button press. Adding a unidirectional association made it almost 100% reliable on the zen26 and it seems 100% reliable now that I have switched both pairs to the zen76.
Note: the antenna mod seems to have helped with the speed as well, which I would not have thought would have changed the speed of an association.
Both pairs have this setting in one switch only
Not that I have had my hub turned off very often, but when the hub is off, the association is slower.
I have thought about removing the association and moving the control back to the BC … but have resisted so far on the basis “if it ain’t broke”
Just an update here- it appears this is a bug that needs to be worked out in the firmware, which a month ago they said was 2-3 weeks from release. Anyone know how long it typically takes Zooz to turn around updates?
I have had updates back in a week but then other times it has taken months. I would follow up with them next week and ask if its available yet. A gentle reminder that you are still patiently waiting. Let me know if they send you anything. I like to keep up on the firmware to make sure nothing has changed that I need to account for in my drivers.
