Read Sungrow inverter data from websocket

This library is used to read real time data from Sungrow inverters with the WiNet module that expose the websocket interface.

Known supported inverters:

• SH8.0RT (SH6.0RT and SH10.0RT likely too)

To check if your inverter is supported, simply try it out!

Installation

Installation is straight forward:

pip install sungrow-websocket

Command line interface

The command line interface is quite simple:

sungrow-websocket <host>

<host> is the hostname or IP address of the inverter. Check your home router for the inverter (maybe registers as espressif).

You will then get a table with the live data:

+---------------------------------------+-----------+
| Item                                  | Value     |
+---------------------------------------+-----------+
| Device Status                         | Standby   |
| Bus Voltage                           | 16.0 V    |
| Internal Air Temperature              | 28.6 ℃    |
| Array Insulation Resistance           | 997 kΩ    |
| Daily Self-consumption Rate           | 23.8 %    |
| ...                                   | ...       |

API

Using the library is easy:

>>> from sungrow_websocket import SungrowWebsocket
>>> host = "your-ip-or-hostname"
>>> sg = SungrowWebsocket(host)
>>> data = sg.get_data()

data is a dict of identifiers mapping to InverterItem entries:

>>> from pprint import pprint
>>> pprint(data)
{'air_tem_inside_machine': InverterItem(name='I18N_COMMON_AIR_TEM_INSIDE_MACHINE', desc='Internal Air Temperature', value='28.5', unit='℃'),
 'bus_voltage': InverterItem(name='I18N_COMMON_BUS_VOLTAGE', desc='Bus Voltage', value='16.0', unit='V'),

The name entry is the internal name of the item, while desc is the clear description. This is loaded according to the locale (en_US by default) and can be set as parameter to the class:

>>> from sungrow_websocket import SungrowWebsocket
>>> host = "your-ip-or-hostname"
>>> sg = SungrowWebsocket(host, locale="zh_CN")
>>> data = sg.get_data()
>>> from pprint import pprint
>>> pprint(data)
{'air_tem_inside_machine': InverterItem(name='I18N_COMMON_AIR_TEM_INSIDE_MACHINE', desc='机内空气温度', value='28.5', unit='℃'),
 'bus_voltage': InverterItem(name='I18N_COMMON_BUS_VOLTAGE', desc='母线电压', value='16.0', unit='V'),

If your locale is not supported, it will fall back to en_US.
