Okay, I see...
To ge the extended functions of a high end brewer like the Ninja, it's just not going to work with a smart plug. You are literally going to need, well... a smart brewer that allows you to integrate say wtih Alexa routines to get where you are trying to go.
While not the Ninja, maybe something like the Atomi 2nd gen WiFi coffee maker? It has Alexa integration, adjustable brew strengths (regular or dark). Not as adjustable, but certainly something workable for your goals I think... https://amzn.to/3wwbkrH
It IS really nice to be able to get up in the morning and have the coffee ready when I roll out of bed.
Of course if you just need a carafe of coffee made at whenever your routine fires off, then a smart plug and any old plain non digital coffee brewer with an on / off switch left to the on position will do the job. https://amzn.to/3zDFifB
Heck, if you were local I'd give you my old one. I have a Mr. Coffee I bought about 6 months prior to when COVID kicked off, and I was working a different job. Once I left the job I took my coffee maker home with me... (Cheap organization wouldn't provide coffee, coffee maker, nothing. We were lucky to get water...)
