The device I have has the standard clamps which I attached to the mains line which transmits to a receiver connected to the router. As the transmitter is battery powered it's a DIY job as you don't need to power it from the board.
Not sure does it integrate with Home Assistant tho. If HA can integrate with ZWave devices then Aeotec do an energy monitor which could work.
Decent list of options here https://www.smarthomeperfected.com/b...ergy-monitors/
if it's any help
There's a RasberryPi based monitor which might be worth a look as it's open source so more likely to be integratable
