I am receiving similar errors to MnM001 and have been spinning my wheels on it for a couple of days now:

........however others including yourself have this working with your code so im not sure where I am going wrong. I have messed around with the IP & port but no luck. I can turn the plug on\off using the another HSxxx script (tplink-smartplug.py).
Please Help!!!
