Hi,
I managed to connect to this inverter from Home Assistatnt according to description. I connected via the RS-232 port built into this inverter. Here is my configuration:

Could you check it and say what can I improve. Thanks.

It looks like this:

This inverter has also ability to connect over wifi, but I couldn't integrate it with Home Assistant. I checked the control board on this inverter and looks like this:

It has built-in esp01s. I can connect from phone over wifi with this inverter and in application Wifimonitor I can check the inverter's parameters. Do you think I can connect with this esp and do something on it from Home Assistant? I am new on esp, that's why I am asking ;-)

[syssi]

I'm confused. Does the pipsolar component work in general?

[MarekOleksik]

Yes, it works perfectly. Good job. I can view all parameters in home assistant. But I wonder if I can use the built-in esp which is on the inverter, and how to add entity to measure energy generated by this inverter to add to energy panel in home assistant.

[syssi]

Is the ESP01S soldered to the mainboard or could you replace the ESP easily?

You could attach another ESP to RXD and TXD to sniff the communication between the mainboard and the ESP01S. Flash this YAML configuration to the sniffing ESP: https://github.com/syssi/esphome-seplos-bms/blob/main/tests/esp8266-uart-sniffer.yaml

[MarekOleksik]

The ESP01S is soldered to the mainboard. When I find some time, I will solder my esp with this sniffer to the built-in one and check what will happen ;)

[syssi]

If you are lucky the ESP uses the same protocol as pipsolar and acts as a "remote control" of your inverter.
