Has someone already rebuilt a energy device detection like discovergy does?

Discovergy announces a beta feature where it discovers several devices in your household depending on the heuristic based on the wattage/phase in your house:

Discovergy (see the beta feature)

This should be possible to rebuild in HA if you know what devices hang on which phase.
Has someone already worked on this project idea?

Created this account just to raise the same question.
Added a shelly3em recently to HA and was wondering, if there is already an addon/integration available allowing to use this data to detect devices based on existing consumption patterns.
Alternatively, this could be also trained manually.

Is this similar to what Sense does? I would be interested in exploring this… I am familiar with machine learning models and would like to explore this further. There is definitely interest within the scientific community for these approaches called Non-Intrusive Load Monitoring. See this Nature article.

I use a website for my current smartthings setup and he apparently is able to do this for a specific aeotec device. But I am interested in moving to Home Assistant in the near future so I would rather invest in a solution that HA can leverage.
