My use case is 1 TRB145 reading 9 x kwh meters via modbus over rs485. I have configured the serial client to poll the meters successfully. however when I try to send them using data to server (mqtt) i am only getting one or two meter readings per message. Are there limitations to how much can be sent each message
I would like to have all readings (there isnt much data) in one message.
Thanks in advance
