# HA Addon for Daly Smart BMS
Home assistant addon that monitors a Daly Smart BMS through UART USB and publishes the data to MQTT. Has MQTT discovery build in, so no need to add the sensors manually to HA.

# ![bms image](https://sc01.alicdn.com/kf/H357b7272ba0344eabd0c33c20101d0c7N.jpg)

Based on the protocol docs found here https://github.com/jblance/mpp-solar/blob/master/docs/protocols/DALY-Daly_RS485_UART_Protocol.pdf and the discussion here https://diysolarforum.com/threads/decoding-the-daly-smartbms-protocol.21898/

The main code is in monitor.py, if you want to expand or change it.

## Install

Add https://github.com/MindFreeze/home-assistant-addons to the addon store repositories and you will get a Daly Smart BMS listed there.
Note that this assumes the BMS is /dev/ttyUSB0. If you have other USB to Serial devices connected this might be wrong.

## Energy and power

You can do this easily. For power in `W`, just create a template sensor and multiply `current * voltage`. https://www.home-assistant.io/integrations/template/

Then to get `kWh` for energy you can create an integration sensor from the power sensor. https://www.home-assistant.io/integrations/integration/
