wombatt is a set of tools to monitor batteries and inverters, and to send commands to inverters.

Inverters supported:

• Any that can handle the PI30 protocol. Known to work:
  • EG4-6500EX
  • EG4-3000s (unconfirmed)

Battery/BMS supported:

• EG4-LL
• EG4-LL-S (unconfirmed)
• EG4 Lifepower
• Pace BMS Modbus (SOK, Jakiper) (unconfirmed)

wombatt can use direct RS232 or RS485 connections, or TCP to communicate using Modbus RTU, Modbus TCP, and slight variations of Modbus ASCII.

The data can be exposed via console, web server (txt, json), or MQTT (Homeassistant auto-discovery topics automatically added).

See wombatt command documentation for more details.

Docker images are available at https://hub.docker.com/r/gonzalomono/wombatt.

Use any recent release tag or latest for docker image tag:

$ docker pull docker.io/gonzalomono/wombatt:latest
$ docker run --device /dev/ttyS1:/dev/ttyS1 -t gonzalomono/wombatt inverter-query -p /dev/ttyS1 --commands Q1

To compile wombatt, you need a working Go setup. Then check out the project and run make to compile the wombatt binary:

$ git clone https://github.com/gonzalop/wombatt.git
$ cd wombatt
$ make

And you'll get a wombatt binary.

If you want to cross-compile for linux, windows, and Mac:

$ git clone https://github.com/gonzalop/wombatt.git
$ cd wombatt
$ make -f Makefile.release release

And you'll get the different binaries under build/ and tarfiles under releases/.

The following video shows how to install from source and run wombatt to monitor 6 lifepower4 batteries. Note that the steps to build the binary from source can be skipped if you get the ARM or ARM64 binaries from the releases link above.
