Energy Module in SmartThings is Not Working for my Samsung A/C

Recently I purchased Samsung AC (AR18CY3YAWK) and was able to connect to smartThings and control AC with the provided controls. However, I am unable to connect to Energy module but HomeCare is working well for AC. Can someone help me provide some inputs on why this is not working?
I wanted to measure the usage of the Air Conditioner but this module is not working.
