The only graphical programming language I have used is Labview, which I actually found to be good for running basic sensors/actuators. My biggest complaints about it aren't actually related to the graphical element, but the tooling itself: long compile times, horrid window management. The only language level complaint I have is that the data persistence model is buried in menus, and not readily visible (so if you have a function for computing a running average, by default, it computes the average of all values put into the function anywhere in your program, but you can set it to have a different instance at each spot you put the function). I wouldn't use it to write things that are typically considered "programs", but there is a wide range between full programs, and things that we want to be able to make the computer do
