Looking for help to set up an open source charge controller shield + vt100 emula

vt100 is an excellent means of creating a simple machine control panel that is more reliable than computers. In the automation industry, reliability is super important because when something doesn't work, it can cost thousands, even hundreds of thousands of dollars, so we tend to gravitate towards simpler stuff that doesn't crash on bootup or tangle itself all up into a mess. B&R automation is doing this (very popular german line of plcs) and I think it is a very good idea. On the other hand, I think a good open source control panel needs to support some other standards as well.
