Removed, reset, readded, tested works with generic dimmer DHT, then updated to Zen77 (instant on/off)& immediately fails via Zwave. Only works at the paddle. This is my 5th power cycle.
The device should get assigned the ZEN77 handler during inclusion.
Post the device’s raw description shown in the ide.

I’d love to see a video of that process. With the new ST app, you add it by “scan for device” or “scan QR code”, either one automatically assigns the default Zwave generic. You then have to go into IDE & “edit device” and manually assign custom handler.
In the 3 years I’ve been using ST, that is how all Zwave devices seem to work when adding a new device & adding a custom handler.
Am I missing something?
I’ve joined devices thousandsof times while writing/testing well over 50 z-wave handlers and I’ve never had a device that I couldn’t get to join with the correct custom handler automatically during inclusion. (V2 & V3 Hubs Only)
That being said, when Edge Drivers went live they messed up the onboarding process and now it sometimes takes more than one attempt to get S2 Authenticated devices to join with the custom handler.
I’ve found the Scan QR Code inclusion process to be the most reliable, but devices still get assigned the correct custom handler when joining using Scan Nearby or selecting an item from the brand list.
I had you post the raw description because if the mfr, prod, and model were blank then you’d need to reboot your hub, but they’re not.
If you’re manually changing the handler then the initialization code isn’t getting executed so while at the top of the device’s details screen swipe down. You should see a refresh icon for a moment or the screen flash.
After doing that open the settings and change one of them.
This is how the in app device screen looks like. It doesn’t show FW or Status… my previous switch the Zen72 worked perfectly, but I ended up going with the 77 to see if it would avoid flickering with fixture, which it does! 
sadly the device handler for it is what is driving me bit nutty. I tried refreshing, changing a setting… same result, it will randomly show offline; etc… but it will never turn light on using it, unless at the physical switch or if I use the generic or zen72 handler.
Fixed! I deleted the DH, reset device, added handler back… then re-added device, changed from the auto installed generic to the Zen77…. Boom! It showed up properly this time… works finally! Ugh that was weird.

That was weird, but after you mentioned deleting the handler and re-creating it I remembered that I have seen that happen before with a different handler.
I still find it odd that custom handlers don’t get assigned automatically during inclusion for you so do you have a regular SmartThings hub that’s either V2 or V3?

Yes ST hub 2018 v2
Just FYI all of my Zen7x series switches added with the generic DTH and had to be manually changed to your custom dth. They all work well so no complaints. Using V3 hub
That’s so weird because that rarely ever happens to me. Are you located in the US region and what method of inclusion did you use?
Yes, in the US on the V3 hub and Android phone. I use the scan QR code to include. They all work great so thank you so much for your hard work!
Does the v10.10 & 10.20 version work with this driver?
Is there an edge driver for the Zen77 yet?
Thanks
No, but there might be one available next month…

There’s a driver available for the Zooz ZEN77 S2 Dimmer on Zooz’s Edge Driver Channel.
