M-Bus (Meter-Bus) library and examples
#17
RTU is Modbus, not M-bus. Don't enable it for the port that you want to use for M-bus.
Only a single script must access the port at any time. Simply reading data from the port won't produce anything. Meters won't send anything without a request from the gateway.
Most likely you need to set short addresses as stated in the integration guide. Connect only one meter to the bus, set the short address then run the scan.
Also only one GND needs to be connected.
