Update associated devices through UI7 or mobile

I?ve got a Figaro FGD-211 dimmer, built in with a momentary switch. This device has no lamp connected to it. It?s associated with a Popp Wall Plug Dimmer.
On the Fibaro, variable 18 (synchronizing the light level on associated devices) is set to 1.

When using the momentary switch I can control both on/off as the light level for the Popp dimmer.

When I try to set the light level for the Fibaro dimmer through the UI, or any mobile app, the level for the Fibaro dimmer is set. But the light level on the Popp is not updated, while I expect to sync the light level, because of the association.

I?ve got this setup also with Fibaro FGS-211 Relay switch and a Popp Wall Plug Switch where I can use the momentary switch for switching the on/off state of the Popp, but can?t use the Fibaro to do this through the UI.

I can?t find any parameter in the documentation for the Fibaro or the Popp that can cause this. Anybody has any suggestion?

This is the weakness of Direct Association
When you trigger the device from the Vera the target device will not pass long the instructions to its associates, this is normal.

To fix this, you should either just use the Popp in the UI, or setup scenes/PLEG to watch for changes on the Fibaro, and trigger the same change on the Popp. Or other trickery.

Thank you for your answer. As Vera doesn’t support a trigger for scenes when light level is changed (only on/off) I think I’ve got to use PLEG. Will look into that.
