Yes, I understand. The fact is, I am going to say thank you to you, Roberts, because I know that if someone come and ask me for a product that I do not offer, I will be responsible for telling him/her the place that DOES offer this product. That is true for Raspberry Pi Single Board Computer running OctoPrint as well —— If someone asks whether or not I have a multifunctional 3d Printer Web Interface that can control and monitor 3d printers remotely, I do not have one, but OctoPrint from OctoPrint.org is definitely that 3d Printer Web Interface! Their site is here: https://octoprint.org/.
