Xiaomi Bluetooth Devices Integration - Temperature and Humidity Sensor

Hello,
I installed and Home Automation Green in my house and migrated all xiaomi devices to it, is very cool.
I’ve a LYWSDCGQ/01ZM Temperature and humidity Sensor that I can’t reach to integrate. In xiaomi account it is connect to my Yeelight Ceiling lamps (they have bluetooth gateway inside) and everything works.
For HA, how can I make it connect? It’s possible to use the bluetooth gateway of the lamps, or I must have a specific gateway?

Thanks for your Help
