Smart plugs 30 amp

I would like to get some advice.

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)

May or may not be the same use case, but would this help?

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.
