Ok so am using RPI all the time, for a main client in a geotechnical lab.. The devices are in either - a sandwitchbox with RPI touch and pyqt5 interface stack - or on a large monitor, with a Status RPI on the back in air with HDMI showing "status" ie test attendance.. )there's 6 of these) - or a desk + screen, rpi velcroed on back with mouse keys etc So can we "automate the above".. preferably with python fabric..
