Where did the Advanced Send Z-Wave command option on the device page go as discussed below? I am trying to set up Direct Associations and this seems like the only way to do it.
It disappeared many platform versions ago (and wouldn't work on Z-Wave JS nowadays anyway).
There are some drivers that can set association. Some might be written for your specific device. What is it? Others are more general. I know this community offering can at least view but might be able to set as well: [RELEASE] Z-Wave Universal Device Scanner.
In the event you need something not found anywhere else, if you know how to format raw hex commands for the legacy Z-Wave stack, writing a driver that does exactly what you want isn't that much harder -- and likely easier if you don't.
You can view and set the Associations with my driver linked above, if the device is new enough to respond to the association group info queries.
Then there is also this much older tool which should work on any device: [BETA] ZWave Tweaker port from ST
There is also this tool linked here: Need direct ASSOCIATIONS - #3 by MrFarmer
This is a Zooz Zen 32 scene controller. They have custom drivers that allow you to set associations for their other devices but not this one.
I will try the Device Scanner. Thanks.
