i have hubitat C8 hub.
i worked with zwave-js-ui, and have the option to make assosication between devices,
which means, i don't need rule, pressing on one button, 3 other endpoints are toggle to this button.
how i can achive z-wave group association in hubitat?
don't want to use rules.
Some custom drivers have the ability, not Hubitat stock drivers because they don't believe in associations.
Also, I've found out that if the hub is unplugged, the actions are very very slow, at least for Zooz products. If the hub is shut down, but not unplugged, the Z-wave radio is still active and it works fast. This is for Zooz anyway. Maybe not true for other companies, I don't know.
I tried that tool mentioned, I THINK, but it was a long time ago-couldn't get it to work.
Here is a snip from a custom driver for my GE/Jasco switches:
The driver has tp be specially coded to be compatible with that app, so pretty much only Inovelli AFAIK.
This driver can set regular and multichannel association on any device. Instructions in the second post, if not needing multichannel you just use the DNI without the :1 for an endpoint.
