I´m looking for a smart plug which connects to HA, I need to be able to turn it on and off and read it´s power consumption ( instant power in W or kW not energy in kWh)
The issue is it needs to be able to sustain 7kw (30 amps at 230v)

Sorry to say that I doubt you will find a smart plug that handle current that high.
Even switching that current will require a power relay or contactor Francisco. I would suggest getting an electrician involved as they will be able to install clamp meter or something like a Schneider power tag in your switchboard -
While they are there, get them to install a contactor with a low voltage coil so you can switch it on and off.
