I’m looking to do the same thing with a wifi connected Nespresso Essenza Plus. So when I wake up in the morning I can ask Alexa via a speaker in the bedroom to make a coffee.
Do you figure this out already? Most of the steps for this should be pretty easy to do (the Nespresso machine power on can be done with a HA integrated wifi “smart” power plug, and the Nespresso plugged into that), but I’m looking for how to send the command to the address of the Nespresso to make the coffee. There’s a couple of other discussions on remotely managing Nespresso machines via Bluetooth, perhaps those can be adapted to use the wifi IP/MAC address?
