Well I changed the connection type for the sensors due to the above issue. [image: upload-22f96b88-66e7-4431-b337-a78b9637ce05.jpg] Tested and again after 2.5 days, it locked out on a sensor com error. So after some thought, I realized, (not sure why I didn't before) the system is not going to be 100% bullet proof, so instead of moving to a hard fault, I recoded the error handling section of the sketch to attempt to handle the occasional hiccups in reading the sensors. Pushed new sketch to Github and am testing now. It will interesting to see just how many times the readings fail. I shall see.....
