Hey guys
I’ve got two Fibaro double switchs and I want to link the s1 channel of the one with the s2 channel of the other and vice versa. How do I do this inside ha?
Cheers,
Rico
If you use z-wave js UI you do it in there. For ‘plain’ z-wave js I would not know. Which one do you use?
If you have both devices in HA, and they both show two switches, then you can use automations to link them together.
How do you want them linked? If you want device1 S1 to always match device2 S2, then you can use a blueprint-based automation to keep them synced. If you have a different type of link in mind, you would use a different automation.
Since you used the words “associate Z-wave” it sounds like you want to use a Z-wave-specific feature called “direct associations” which allow one switch directly control the other without HA in the loop — which is neat, but in my experience is not great for keeping things synced, but depending on your needs and your vendor documentation that might work as well. As noted above, they’re only available if you use Z-wave JS UI as your back-end driver/controller software.
Direct associations also work when HA is down. They are essential if you want your home to function when HA is somehow not working as it should. Associations can prevent divorce in severe situations 
For on/off I see no reason why sync would not work, assuming association commands are only sent when the light actualle changes state. For dimming, I highly doubt syncing is possible this way. But the blueprint is not designed for that either.

Thx for your replies.
I am using Z-Wave JS and my scenario is this:
I’ve got two bedside tables with one of the switches each. One channel of each switch is to control the own side and I want the other one to control the opposite side. First I started to create automations, which worked ok. But on top I’ve got a wallswitch which also controls the Fibaro switches. And than I ended up in multiple automations/synchronisations interfering each other. So I thought that the direct association as a feature of z-wave could be a way.
But I will have a look at the synchronisation blueprint.
Thanks again, the blueprint did the trick.
