SMA Webconnect library for Python 3. The library was created

to integrate SMA inverters with HomeAssistant

See  for more information on the SMA solar

inverters

Other SMA interfaces include [SBFspot](https://github.com/SBFspot/SBFspot/) and a

Python [adaptation](https://github.com/TD22057/T-Home/)

## Example usage

See [example.py](./example.py) for a basic usage and tests

# Home Assistant

The Home Assistant sma sensor documentation can be found

[here](https://www.home-assistant.io/components/sma)

> ---

>

> **This library uses Webconnect.** ~Modbus~ is not supported

> 

> **If you can access your SMA via your browser, this might work for you.**

>

> ---

If you access your SMA WebConnect via `https://` you should set both

`ssl: true` and `verify_ssl: false`.

Daily usage is not always available from the SMA WebConnect interface.

It is possible to get around this by using a

[utility meter](https://www.home-assistant.io/components/utility_meter)

or more recently from the Energy management feature in Home Assistant

### How to debug this addon

1. Ensure you can access your SMA from your browser

To enable detailed logging in Home Assistant, you can add the following to your configuration

```yaml

logger:

  default: info

  logs:

    homeassistant.components.sma: debug

    pysma: debug

```

## Energy Meter

This library can read the second version of the emnergy meter, there is a seperate Home Assistant OS Addon that could also read older Energy Meters directly. See [Energy Meter](https://github.com/kellerza/hassio-sma-em)
