Len Beasley. Sorry about the first one. I am trying to use the Rasberry Pi to connect to a number of ESP8622 chips and display the data on the Rasbbery Pi monitor. What software would I need on the monitor? Could it be in the form of spreadsheet with up to ten different va;ues.

Great Video, I've got a question though...When you set up your Sub and Pub messages in mosquitto do you need to give each device (ESP32) it's own unique name? I want to use the ESP32's to deliver data like Water and Fuel Tank Levels wirelessly back to the Rpi so I can then use the data in a Dashboard. So does the ESP32 for the Fuel tank sensor need it's own Sub and Pub called Fuel Tank 1 and then 2 or Water tank 1 and 2 etc... I'm not a Software guy...but I'm trying to set up my Sailboat with Rpi's as the system backbone.
