Is there an esphome for lifepower4

YAY, glad it worked out for you!

@goldserve did you put the info on GitHub?

Btw, I am running a m5stickc with Tasmota to monitor my EG4LLv2 batteries. I use the Modbus TCP bridge and query the data and publish from another machine (the one that runs HA). The code is on GitHub at https://github.com/gonzalop/wombatt (screenshot and HA dashboard YAML here). It supports Modbus RTU, Modbus TCP and direct serial connection to the batteries. For inverters, I use the same tool but through a TCP to RS232 bridge running on an Atom lite.

Adding support for lifepower4 should be straightforward, but I would need someone who is willing and able to test things (nothing destructive, the monitoring command only issues 'read register' Modbus commands).



The pic shows the M5Stick with an RS485 hat, and 2 atoms with the RS232 interface, one for each inverter, and a USB hub powered by a small UPS. The RS485 hat is connected to a wago where all the batteries RS485 wires are plugged into.

I have a fork of goldserve master branch minor tweaks for my environment and changes to the HA discovery I am using this devices and the script runs in a docker container

I am down to test

Thanks a lot for for your help testing the code with your lifepower batteries!

Now we have support for monitoring lifepower4 batteries in wombatt!

This project is in the "right direction" for many BMS not specific to lifepower4 though https://github.com/syssi/esphome-jk-bms

anyone interested in adding support for the Eg4 Wallmount batteries? I have 4 and am willing to test and help

We actually don’t know what bms is used in the wall mount batteries. You can sniff canbus to see what is being reported by the battery.
