Another completely noob question ... #2

Does this add-on rely on connecting the UART output directly to a USB input of the Raspberry Pi (or another device) that I am running my HA instance on?

If not, what is the UART output cable actually connected to ... another Pi device?

Yes, this assumes that you have connected HA to the BMS with the USB-UART cable. Alternatively you can just take monitor.py, see how to set the env variables from run.sh and excute the python script on another pi connected to the BMS.

How I actually use it is, I have an extra raspberry pi running a barebones instance of HA, connected to the BMS UART, and I run the addon on that. This allows me to use it as a HA addon, with backups, updates, etc. without running a cable to my main HA server but the data is actually sent to my main HA's mqtt server. I also have other addons running this way that connect to my inverters.

Thank you for the quick response. The way you use it is the way I want to utilize the add-on. My HA server and my BMS/battery are too far apart to be directly connected.

This add-on is simply a monitoring tool correct? You are not able to change any settings on the BMS or are you?

MindFreeze commented 2 years ago

It can be extended to set settings as well but currently it only supports monitoring.

I don't plan on adding settings because I don't need to change anything after initial setup. And if I do need to change settings, I can plug in the Bluetooth dongle on the BMS and configure it through the official app.

That makes sense. Thank you.
