Close #60

[TillFleisch]

@quack3d can you check if this fixes #60 for you?

[quack3d]

Seems to work like v3.0.0. 👍

[quack3d]

Looks like I spoke too soon. Turning it on it goes to 'Cleaning' and then 'Brewing Latte Macchiato' and then back to 'Cleaning'. Same thing when I turn it off.

[TillFleisch]

I do occasionally also see an invalid state (Espresso) when starting the machine(only once). This was also the case prior to any of the related changes. I should probably rework the state detection some day but it hasn't bothered me enough yet (I'm also somewhat time constraint from time to time).

Is the major machine breaking problem fixed? Do the Latte/Americano options work as intended (in contrast to the wrong behaviour described in #60)?

[quack3d]

Yeah, everything else works as it should (Latte/Americano etc). But since it's reporting a Latte every time I start and shut down the machine I get weird results in statistics. For each coffee there are 2 Lattes. 😁

In the code you changed, does it make sense that v3.0.0 does not have this issue but @main now does?

[quack3d]

Today I have that same preparing - latte - preparing - latte - preparing - latte - cleaning - latte - cleaning - latte - cleaning - latte cycle... It has been just a few latte reports this week. 1-7 depending on how many coffees but today it said 74 lattes. I did upgrade ESPHome today. Not sure how that could affect anything.

I went back to

  But strangely I still get a bunch of Brewing Latte Macchiato when powering on the machine. So it seems like the changes after v3.0.0 is not the culprit. Now I'm not sure what version to choose.
