+One day i'v realised that notebook with a serial console is very good diagnostic tool, but i want more compact tool to get maximum available information from heat pump. So this "fast diagnostic display" appeared. It fits everywhere and with a good power bank it can work 2-3 days long, without any additional power source. The diagnostic display is build from scratch, no PCB and housing here, because i do not see this device as a permanent-mounted display for the end user.
