In principle, would it be possible to write DE1 UI that gives the user full real time control?
I recognize it would not give the kind of tactile feedback that a level machine gives but would it be very different from a needle valve machine?

DE1 already has a grouphead controller if that's what you want but most users find it unnecessary. There is also a fully dynamic language coming shortly for writing complex and adaptive profiles.

I'll just restate though that I use the ghc very occasionally when I'm way off on a profile, and despite that lack of use almost never have anything short of a very good shot given my normal approach to shots, and almost never sink a shot. With constantly changing coffees and many open simultaneously.

Does the DE1 measure flow based on an estimation at the pump only? Or can you also use the measured flow from a Bluetooth connected scale?

FWIW; This recent post indirectly references the challenges perhaps Jayson is referring to above, along with potential improvements in that area: https://coffeeadastra.com/2021/07/12/on ... ed-solids/

I think this example highlights another key consideration for those choosing a more technical vs analog espresso machine (beyond the obvious user interface differences); and that is if you choose a technical machine you must also have faith that problems with the implementation are solvable via software and/or incremental hardware updates.

Would you mind elaborating on your thoughts here because my impression of Gagne's post is that it highlights insights that can only come from a Decent and has nothing about a "problem" with using a Decent vs a manual machine.

Because the flow model depends on so many parameters, it is not rare to see the flow rate being off by 10-20% on the DE1. Therefore, I thought we could not reconstruct something useful and repeatable in terms of a live TDS curve during a shot that is based on the difference in output weight minus input flow of water. Worse, the measurements provided by the Acaia scale are very noisy, especially when estimating the change of weight per unit time.

As someone who writes software for a living, I'm impressed by their ability to estimate this closely. At first blush, it sounds like a very complex thing to model. But also as someone who works with software for a living, I don't like software that guesses and I especially don't like software that depends on software that's guessing. People (trained, usually highly educated people) using software that guesses is one thing, but other software using guessing software almost always doesn't account for known flaws in the dependency's models. So you have a scale that's using software to guess and an espresso machine that's using software to guess. I find it hard to believe this isn't the Babbage problem.
