Looking for recommendations on an energy monitor

That highlights that there's no direct integration with HE and that folks are bringing it into HE through Home Assistant.

So, you would need a device to run Home Assistant (just setting it up can be cumbersome), then setup the integration in Home Assistant, and then use something like [RELEASE] Home Assistant Device Bridge (HADB) to get the data into HE. Or just leave it in Home Assistant and run dual systems for reporting/monitoring.
