In an attempt to have one central remote (not Smartphone) in our living room, I ordered this neat looking Livolo remote. It feature 9 buttons + 3 different 'rooms', giving me the option to connect 21(!) switches in Domoticz.

That all sounded wonderful, but I am running into a challenge now

I've tried the sub/slave setting, but that doesn't actively switch the master device, and will not give me the toggle functionality I want.
I can create individual Blocky scripts for every single button, but I assume there is a less manual (3 x 9 blocky-scripts) option.
Any ideas? Couldn't find people trying to connect the Livolo remote on this forum yet.
