Has someone read Aurora TRIO-20.0/27.6-TL-OUTD Data over Modbus? I am trying to read it, they work fine on Aurora Protocol but they don’t work on Modbus. and how emonPi can read that data? I have its register map

Did yu try to use the modus tcp interfacer of emonhub ?

github.com

openenergymonitor/emonhub/blob/emon-pi/conf/interfacer_examples/modbus/readme.md

# Modbus interface

This interface starts a modbus TCP connection and retrieves register information for publishing via mqtt to emonCMS
For a FRONIUS Inverter specific config to log inver `model/brand/software`
versions on init to the log file change the Type setting to EmonFroniusModbusTcpInterfacer

## Usage and configuration

There is a sample modbusTCP.emonhub.conf file located in this directory.
The rType and datacodes must match. Use the table below to assist.

### Sample interfacer config within emonhub.conf

Sample configuration for modbus TCP clients 

```
    [[ModbusTCP]]     
        # this interfacer retrieves register information from modbusTCP clients 
        # retrieve register information from modbus TCP documentation for your inverter.
        Type = EmonModbusTcpInterfacer

This file has been truncated. show original

Yu need to install pymodbus on the emonpi
