Ciao @alexdelprete,
You might also want to look at the integration I linked in previous post, there’s a trigger section that the dev says is necessary because of the way the switch behaves.
Thank you for pointing it out, I’ll include that required check in the blueprint. 
If you need me to test/debug something for you, please let me know, I use ZHA with a Connbee II. If I can help finding the action mappings please instruct me on how to do it and I’d be glad to help you.
As reported in the linked GitHub issue, I was able to identify the mappings for both ZHA and deCONZ, but thank you for being available anyway.
It’d be extremely helpful if you could test the blueprint before making if publicly available. I’ll let you know on GitHub as soon as the PR with the new blueprint is ready for testing. 
For now I’ve done everything manually with standard automation, I have 1 automation for each button for each switch. The list of automations is exploding since I have many switches. That’s why I need something like your integration.
Great to know, so a blueprint will definitely be useful in your use case. 
Thank you for your help and for your suggestion!
