BTicino Living Now is based on Zigbee 3.0 and AFAIK is a closed version, so no local integration with the Living Now gateway is possibile.
A possibile integration could be using “works with Legrand” cloud APIs, but it must be investigated the API license part and in any case it would be a totally different binding structure/approach.
