Hello,
This question was asked few times in the past but maybe someone came up with a solution,
My goal is to transfer the data from the grid meter to my Cerbo, a new cable to run is inconvenient, so I've tried to configure 2 modbus gateways one as a master and one slave to carry the signal over Ethernet but something is wrong and can't figure out what exactly.
I can see the Cerbo (192.168.2.239) is sending requests and getting replies but they don't engage in data transfers too much, however with the Carlo Gavazzi software (192.168.2.148 my laptop) everything communicates fine, is there a specific settings to be set to the meter? the meter is currently set to address 1, parity none, baud rate 9600, stop bit 1. other important details the meter communicated fine and probably still works with my raspberry pi via USB directly.
Any input is appreciated, best case would be to make the Cerbo read the meter via TCP/IP
Thanks in advance George
