Model: YRD410-ZW2
Zwave module Firmware: 1.81
It was detected by HA, but none of the useful entities is available, except last seen.
Any suggestions on how to fix? Re-Interview doesn’t change anything.
I have three of the YRD450-ZW2 locks. I don’t recall anything odd with them except I did need to have them close to the controller to pair them.
Thanks Jeff!
I will try removing and pairing again.
I have never removed a zwave device. Any special recommendation regarding these locks? Do I need to factor reset it? Or how to put the ZWave module in discovery mode?
Look in the docks. There is generally an unpair mode for Z-Wave just like the paring mode.
I think it is called exclude in Z-Wave world.
I removed it. And added it back, but same thing. No useful entities.
Not sure what do try next. 
Remove and pair again, don’t forget to use the S2 security pin.
Did you add the S2 security pin?
Okay, this is hurting my head. I did some searching and think I did need to use the app to get it working. This is not a ‘cloud’ type of thing as the cloud is not necessary in the end.
There is a thread on here about it. I found it 5 minutes ago. But, my laptop froze and I had to reboot. I am going to try to find it again to give to you.
ETA: I think this is it;
Note: I do not use door sense as I already had sensors and had no need.
Thanks for the suggestion.
Sorry for the delayed response, I was travelling over the holidays.
Will try again tonight.
First time doing this, so just to confirm, I imagine the Z-wave host device, in my case a 800 Series Long Range USB Controller, should generate secret keys (the S2 security pin you mentioned) and I should add those to the found device (the lock) so they can talk.
Is that the idea?
Thanks
I am reading the post, but for me, unfortunately, as I said in my original post above, I can “see” the lock but no useful entities in HA. On the Yale Access app, everything seems ok 
.
I wonder whether it is because of the S2 missing or something.
The S2 pin is on the lock or in the manual for the lock. It is not generated. Is you’re saying this, it is very likely you are setting the lock up without the S2 pin. Check inside the battery compartment, on the ZWAVE module. I’m not familiar with the location of the S2 pin on the YRD450-ZW2 but it will be on the lock. It will also have the pin as a QR code or numerical.
@Rodrick couldn’t find any reference to S2 pin in the manual or anywhere for this model. The only code in the manual, is the one to be scanned by the YALE Access App. Doesn’t look like a S2 key.
I also can’t find where to add a S2 key on the device on HA. I am using ZWave JS UI and while I can find the S2 keys for the controller, I can’t find any reference to it in the node(lock) itself. I must be doing something wrong.
Remove the battery cover from the interior side of the lock.
Look for the Z-Wave Smart Module—it’s a small rectangular component inserted into the battery compartment.
On the module, you’ll find a QR code label. The S2 DSK (Device Specific Key) is printed near this QR code.
The S2 PIN is usually the first 5 digits of the DSK.
For ZWAVE JS UI
Open Z-Wave JS UI Launch the Z-Wave JS UI interface from Home Assistant or your browser.
Start Inclusion Mode
Click the Menu icon (usually bottom right).
Select Manage Nodes → Inclusion.
Choose Inclusion Type
By default, Secure S2 is selected.
You can also choose S0 encryption, No encryption, or SmartStart depending on your device and preference.
Enter Device Info
Input the device name and location.
For S2 inclusion, you’ll be prompted to enter the S2 PIN (first 5 digits of the DSK found on the device label or QR code).
Complete Pairing
Click Next to begin the inclusion.
The device will be added securely, and you’ll see a green checkmark and lock icon once successful.

So, there are only 2 things in the lock itself (same as the manual):
- A QR Code that’s for the Yale Access App (to configure the lock basics via bluetooth).
- A homekit code.
Like this:
Then, on the module itself, there is only this information:
I will try calling Yale to understand if something is missing.
Still, thank you @Rodrick !!! Really appreciate the detailed explanation.
Will try this tonight and let you know.
My pleasure, Yale support is good.

Ok! It worked! 
But it’s using S0 Legacy.
I was simply adding the lock via the Z-wave integration and with that, it was adding it unsecurely. If you do it through Z-Wave JS UI and force security, it works.
Here are the steps:
On HA:
- Launch the Z-Wave JS UI
- Click the button in the botton/right and select Manage Nodes
- Select Inclusion and click Next
- Add a name (optional) and click Next
- Select Default option but mark the Force Security checkbox (prefer S0 over no encryption) and click Next
On Yale Access (assuming the lock is already added to the app):
- Go to the Settings (right botton gear icon)
- Select the lock
- Select Smart Yale Module
- Put the lock in Enrollment mode
At any point I could add the pin for the S2. But since it worked with S0, I am happy for now.
Only thing that is not working is the door sense. It works in the Yale app, immediately showing the door is open or closed, but the binary_sensor.front_door_lock_current_status_of_the_door doesn’t change when I open or close. I will do some more testing later.
I am marking this as a solution, but please know that @Rodrick’s reply above put me in the right direction.
I don’t use the door sense as I already had sensors on all of the doors.
