-# Direct Serial emonTx V3 / emonTH
+## Deprecated
 
-Using emoneESP format direct serial
-
-by @owenduffy
-
-Interfacer for serial output from emonTx V3 (firmware V2.4 and above)
-
-emonTx firmware V2.4+ outputs serial CSV string pairs compatiable with emonESP:
-
-`MSG:value,name:value,name:value`
-
-e.g
-
-`MSG:12,ct1:100,ct2:300` ....
-
-Messages **must** start with the `MSG:number` key:value pair. The message number does not need to increment but the interfacer looks for `MSG` as the identifier that the new string is a data string.
-
-Default baudrate is `115200`
-
-## Config example
-
-Add the following to `emonhub.conf` in the `[interfacers]` section:
-
-```
-[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]]]
-           #nodeoffset = 1
-           # nodeoffet can be used for multiple devices. it will change the nodeID as seen by emonCMS Inputs.
-           pubchannels = ToEmonCMS,
