I2C is very short range, it’s meant for connecting parts on the same board. You want something like RS-485. The Modbus protocol, which runs over RS-485 would be perfect for this.

I’m personally not. I’m for appliances with a standard interface, maybe, through which it can be connected to some smart home system.
I do not mean internet access or anything else “smart” in the appliance itself. I mean being able to use the same functions as buttons and indicators offer, remotely. I2C will do.

Yes, from quick googling seems exactly what I want.

For the love of God, I just can’t understand how “needs Internet” became synonymous with “smart” in the appliances market slang. I know it’s what advertisers do, but this one is abysmal.

Well, calling a machine “smart” doesn’t seem smart to me in general

What you have just described could be ZigBee and/or MQTT.

No need for radio even. MQTT - yes.
