Is it possible to put RGB number to select the colour of the kight?
This is the easiest way to get the color I want and all bulb deliver same color. Any other way please let me know.

It’s possible though it’s a little bit complicated. You must turn on LAN control in the Yeelight app, then you can connect to the bulb with telnet from command line on a PC or a smartphone like

telnet [bulb's IP number] 55443

then you can send a command with the RGB value (you have to convert it from r,g,b to one decimal number, for e.g. rgb(255,125,0) is 16743680, so

{"id":1,"method":"set_rgb","params":[16743680, "smooth", 500]}

will set the bulb to that RGB colour. Fortunately right after that you can save the colour as a favourite or as a scene in the Yeelight app, so you have to send it this way only once per colour.
