I’m trying to collect data from an auduino connected to the Raspberry, on which I installed nymea:core. Using the Modbus Commander plugin I would like to read data from the Arduino. First question: Does the Modbus Commander plugin create a modbus master RTU? Currently the arduino is set up as slave. When I configure the new thing “Modbus RTU client”, nymea:core detects that on port ttyACM0 is connected Arduino
Anyway after the creation of the thing, the connection fails everytime.
How does the plugin check the connection with modbus device?
