i have a communication problem with Modbus RTU communication on MyrevPi Connect +.
The communications are working well but, a few hours ago, I had this problem when I launch my Python program (influxDB.py) to read the modbus RTU data from my device. Now not found !
I use minimalmodbus driver (https://minimalmodbus.readthedocs.io/en/stable/) to read directly via mudbus RTU.
This is th error:
No such file or directory: '/dev/ttyRS485'
