Extending bluetooth only device range

Right now I own two Yeelight Candela, loving the product but the bluetooth range is too short.
I am planning to grab Mijia Lamp as well as the bed side light (wifi model).

Would they work to extend the range of the bluetooth?

If not, what kind of product other than ceiling light would work?

Also just want to ask, if the google home implementation will be in soon for Candela? any ETA?
