OK, I'll reply to myself. I got to wondering if I should have installed the Silicon Labs CP210X to UART Bridge VCP Drivers. But, I quickly found out that those drivers which I' [thermo]ve had for a long time in other OS versions, are not compatible with Ventura. The OS tried at every turn to block the installation of that software. The OS won. I'm wondering if the sensor error could have been actually the lack of a driver.
