Support for Homecube/Gosund Smart Plug SP1

[knopserl]

It would be extremly attractive to get a support for the small good looking and cost effective smart plug SP1 sold from many different companies like Homecube, Gosund and others. I have bought tow of them in a bundle for 39€ and the have an ESP8266EX with 1MB Flash and an Energy Monitor chip which is labeled with: HJL-01 J1749CYH D797480E. I was able to solder the 3,3V and the RX/TX connection and read the chip type and flash size and dump the flash, but don't know what kind of energy monitor chip that is (have not found it in the web). If anybody could hack that device and get Nodemanager working, that would be great. That are the links to the product:

As a good start: Mainly the new energy sensor chip HJL-01 need to be supported. Within the ESPurna and Tasmota projects, this was already implemented by extending the common used HLW8012 library.
