Hi all, I'd like to associate the relay button on a Zen30 to a dry contact relay Zen51. I know there's an advanced zooz driver that exposes association groups, but it doesn't appear to support the Zen51 yet. Is there a different way to create an association? Thank you
The association you need to set is from the ZEN30 to the DNI of the ZEN51. I assume you are talking about my advanced driver? The driver does not care what the receiving device is, you just need to put in the proper DNI.
Awesome, did not know that - thanks!
On second look, it may be more complicated. The Zen30 relay button comes up as a child component device, and cannot have its own driver.
Correct, the child is basically a virtual device so you can have a separate on/off state. All the settings are controlled from the main device, including the associations for both. If using my driver you should see "Group 3 ( Relay)", this is where you set the 2 char hex DNI of the ZEN51.
Honestly though, unless you need it to work when your hub is offline (and your house still has power), I would just setup a simple rule in one of the rule apps.
Okay, so - if I change the driver of the Zen30 to Zooz ZEN Switch Advanced, I see Group 2 and Group 3 parameters. It doesn't say "(Relay)", but I'm guessing Group 3 would be used for that separate on/off state?
Secondly, the Zen30 puts the component device DNI as the same number, with a -1. So in my case, the main dimmer is 30, and the relay button component device is 30-1. Do I need to edit the DNI so it's only 2 chars before I make the association?
That's not the correct driver for the ZEN30, I have a specific one for the 30.
Do not edit the DNI, you will possibly break the child device from working correctly with the parent.
From what you have said, you want to make it so the button press on the relay, will toggle the ZEN51, so you need to associate the ZEN30 relay (Group 3) with the DNI of the ZEN51. You do not need the DNI of the ZEN30, parent or child, at all.
Ah, it would help if I had the right driver eh. This makes a lot more sense now. 
Many thanks - the reason I want direct association is it goes to an exhaust fan. Just thinking that since the relay wiring is in a hard-to-reach area, I'd rather it function without the aid of a hub.
I must be missing something. It doesn't seem to be toggling the Zen51. I set the Zen30 Group 3 (Relay) to the DNI of the Zen51 and hit configure. It shows correctly the status of group 3 as the correct DNI (assocDNI3), but does not toggle the Zen51 dry contact relay.
One other trick with associations I forgot to mention, both devices need to be the same security level. You can see this on the zwave details page in the "Security" column.
Both devices are paired without security.
Gremlins be among us.

Sorry I do plan on testing this out with one of my ZEN30 when I can. I do have a ZEN51 but its not even paired yet, but I can test with another device just to see if it works at all.
In the meantime, can you check what firmware your ZEN30 is running? Should be at the bottom in the data section.
No prob! Looks like my Zen30 is 3.00. Looks like there's a new one, which is 3.10. Changelog between 3.00-3.10 says:
- Added parameters 28 and 29 to disable scene control and removed button delay when scene control is disabled (see all settings and details here).
- Added parameter 30 to disable programming functionality from the dimmer paddles so triple-tap can be used for scene control (see setting details here).
Though I doubt that would affect the association group.
This is in the Zen51 manual:
Do associated devices have to communicate within the same group?
No, the associations on the ZEN51 would only be used if you want the ZEN51 itself to command other devices based on its state, but I do not think you want to do that.
When you have the association for the ZEN30 set, it is supposed to send out very generic on/off commands to the DNI you set when you turn the relay on/off, which most devices should understand and turn on/off accordingly.
Can you show a screenshot of your settings on the ZEN30? If you have the "smart bulb" mode enabled there could be some cases where the associations no longer get sent out.
Sure. I did notice that when group 3 is assigned and the relay button is pressed digitally, HE thinks the dimmer was triggered. Not so when it's pressed physically.
There was a bug like this in the stock driver (not sure if it got fixed) which was not present in my driver. But you also have a v3 device and all my prior testing was on a v1 device. I just recently got a ZEN30v3 (and a ZEN51) but both are still in the box.
Just to be complete, can you also post the "Device Information" section for both the ZEN30 parent and the ZEN51. I just want to be 100% certain you have the correct DNI in the association.
Just a small update: I updated the Zen30 firmware from 3.00 to 3.10 with no change in behavior (as expected).
