Unable to change bulb state

Hi, I am able to connect to the bulb and to get its state info back, but when i try altering its state in any way using bulb.turn_off() or bulb.set_state(PilotBuilder(colortemp=color_temp)) the following error message is printed:

Fatal write error on datagram transport

It seems to me that you can't connect successfully to the bulb. Please try to send a nc to the bulb to test the basic connectivity. See here: https://github.com/sbidy/pywizlight/issues/89#issuecomment-947428357

It appears to be something else as the response seems fine.

{"method":"getSystemConfig","env":"pro","result":{"mac":"6c29901***","homeId":763***,"roomId":11***,"rgn":"eu","moduleName":"ESP03_SHTW1W_01","fwVersion":"1.28.0","groupId":0,"ping":0}}

[sbidy]

Can you please try to send the same command (turn off) via nc: {"method": "setPilot", "params": {"state": False}} (replace the part after echo)

[janek515]

It works as expected and returns {"method":"setPilot","env":"pro","result":{"success":true}}
