I hope you don’t mind, I moved this question to a new topic.

The short answer is yes; you will just need to create a new entry in emonhub.conf in the [interfacers] section, you can edit this via the local Emoncms web interface.

There are two options depending on serial format:

1. EmonHubTx3eInterfacer

This interface handles name value key pairs e.g. name:value,name:value. This is the default serial output for latest emonTx V3 and emonTH FW.

Config example:

[interfacers]
### This interfacer manages the EmonTx3 ESP format serial
[[SerialTx3e]]
     Type = EmonHubTx3eInterfacer
      [[[init_settings]]]
           # Un-comment line below if using RS485 adapter
           #com_port = /dev/ttyRS485-0
           # default com port if using USB to UART adapter
           com_port= /dev/ttyUSB0
           com_baud = 115200
      [[[runtimesettings]]]
           pubchannels = ToEmonCMS,

2. EmonHubSerialInterface

This interfacer handles serial with space operators e.g NODEID VAR1 VAR2 VAR3

Config example:

[[SerialDirect]]
     Type = EmonHubSerialInterfacer
      [[[init_settings]]]
           com_port = /dev/ttyUSB0      # or /dev/ttyAMA0 or/dev/ttyACM0 etc
           com_baud = 9600              # to match the baud of the connected device
      [[[runtimesettings]]]
           pubchannels = ToEmonCMS,
