Anyone successfully connected via developer mode threw an android UDP sender?

@myhrmans,
Sending TCP command to Yeelight bulb ( RGB v2 in my case ) using tasker works.
what you need:

  1. install Yeelight official app and enable “3rd party access” also known as “LAN CONTROL”.
  2. in Tasker: add task “run shell” and see in this thread how to send the JSON formatted command through TCP.
    Controlling Yeelight RGBW using terminal / command line
  3. please note some limitation I complained about ( so far w/o any solution, AFAIK its a firmware issue )
    [SOLVED!] TCP commands not working - not getting response

so I can report that sending TCP commands do work - but you need to send the same command to multiple ID, since even if you got only one yeelight in your LAN, its ID get changed almost each time you send it a command.
