What smart hotels are there in Shenzhen?

I remember that the only unmanned hotel in Shenzhen was Le Yi Mansion. There are three branches in Shenzhen, including Shenzhen Bagualing Store, Yantian Shatoujiao Store and Shenzhen Dongmen Store, all of which are popular online celebrity hotels. Last time I went to Bagualing Store, the room occupancy rate was quite high. Because I booked it in advance, there was no delay. There are many smart equipment applications in the whole hotel, including access control, face recognition, intelligent robot leading the way, and intelligent induction appliances in the room, all of which are quite fresh.
