Multibinding use

I am trying to use the “Multibinding” with the path: @Device.attribute.length as shown in the image below.
Is it possible to do this?
Many thanks.

No. You won’t be able to use the “.length” part.

Is there a workaround? With the Hue lights, If you remember, I use a script, but it is recommended not to do it. I am trying to avoid creating a new attribute…

I don’t know. I think you’ll probably have to create another attribute for it.

Ok, many thanks Bill!
