Inverter self consumption from existing entities

[Louix73]

Thanks for the integration, it works relatively ok. Like a few people some unstability on modbus but I can live with it.

My question is, like the instant power solar generation, is it possible to create a sensor that will extract the self consumption of the invertor as it is working?
Basically it is quite obvious that the inverter is consuming about 600-700W a full load for me, so I was wondering if this is possible.
