I’ve just done 4 big control panels for materials testing in a lab, their previous ones had a jumble of panel mounted controllers, buttons, potentiometers and indicators - we’ve replaced them all with a big HMI - the only buttons they have are an e stop and a couple of reset buttons.I've long suspected part of the reason everything (thermostats, washing machines, etc) has an app these days is because it's cheaper and easier to design a UI with a high res colour touch screen than it is to do it with physical buttons and LED indicators or an alphanumeric display.
The beauty is if they want anything adding in the future it doesn’t need any extra wiring, cut outs etc. It’s also much less confusing to look at, with all the info easily displayed. I’m not sure it totally works as well in cars, but there’s likely no going back now!
