Hardware Info and more documentation

[Norm71]

I do have a System from Tewaycell Tewaycell 48V 200Ah 10Kwh All-in-one Mobile ESS Built-in Hybrid Invert and they provided a RS232 to USB Cable with it.

They also sent the PACEexTool but its completely in Chinese.

Now i found your Home Assistant integration. 😀

Can you explain a bit more how i do get the basic connection? I think i need to install the USB driver for Linux first on the Homeassistant Raspberry. Is that possible? Then i have questions for the requirements: paho_mqtt==1.6.1 PyYAML==6.0.1 pyserial==3.5

I dont know how to get the reuirements.

I have Mosquito MQTT and use it already for my OpenDTU and ESP32

I posted in Power Forum but did not get any answer. So i try directly here.

Do you have home assistant operating system, or just home assistant core installed? The addon is meant for operating system.

If you run core then you need to install the dependancies in the requirements file, change the config file to suite your needs, and finally run the script manually. If you need to run the script as a system service, Google will help you out there.

Its Home Assistant Operating System. So with HA OS i dont need the paho_mqtt, PyYAML and pyserial? So i installed the addon and its running. The BMS is connected with the provided Rs232 to USB connector. But how can i verify which port is used (/dev/ttyUSB0) and is there a driver needed?

Thats my protocol: Hello BMS Pace Starting up...

Nope you don't need it, HAOS will handle all of that for you. Just Google how to install addons in home assistant, pretty straightforward.

Add on is installed but I don't get any signal from the USB port. Don't know how to find out which is used in Home assistant

[Tertiush]

Go look in the system menu for hardware info or something like that. Should be usbtty1 or something similar. Case sensitive

It was to early to be happy. That was my Z-Wave Stick. Cable is not listed will try a Waveshare RS232 RS485 to WiFi POE Ethernet Serial Server Converter. Is there any Hardware you can recommend?

[Tertiush]

Nope sorry, just used what I has laying around.

[Norm71]

Solved the config!

So what i have:

2. Rs232to Eth: https://www.waveshare.com/wiki/RS485_TO_WIFI/ETH

Installed your Addon

Configured the Waveshare as follows:

Afterwards the Addon could connect and i directly retrieved:
