## About The Project
Access ModBus data from almost any network connected Sungow Inverter.
On first connection the tool will query your inverter, retrieve the model and return the correct registers for your device. No more searching registers or creating model files.
Register information based on official documentation: Communication Protocol of PV Grid-Connected String Inverters and Communication Protocol of Residential Hybrid Inverters
Has multiple export locations out of the box:
* Console - Log directly to screen
* MQTT - Load into MQTT, and optionally Home Assistance including Discovery
* PVOutput - Load into PVOutput.org
* InfluxDB - Load data directly into InfluxDB
* Simple webserver showing collected data
* and more coming....
I have borrowed HEAVILY from the following projects, THANK YOU
* [solariot](https://github.com/meltaxa/solariot)
* [modbus4mqtt](https://github.com/tjhowse/modbus4mqtt)
* [ModbusTCP2MQTT](https://github.com/TenySmart/ModbusTCP2MQTT)

## Raodmap / TO DO
* Rasberry Pi Docker support
* Full Home Assistant integration, as HACS addon
## Updates
**0.2.2**
* Minor bug fixes
* Add support for some inverter scrapes to fail
* Add support for zero_on_standby, this will 0 registers like temp that 'stick' to the last value when the inverter goes into standy. Handy if you want to graph 0 instead of the last read overnight
**0.2.1**
* Minor bug fixes
* Updated config-example.yaml to clearly explain each option and if it is required or optional
* Replace is_running with run_state, was using bool which was causing errors in MQTT, run_state uses "ON" and "OFF"
**0.2.0**
**IMPORTANT: If updating from v0.1.x please check config against config-example. some options for MQTT and PVOutput have changed**
* Re-write to Inverter scanning code, improved performance and more resilient to failures
* Re-write to PVOutput code, now uploads every 5 minutes as per API documentation, averages all data points over the 5 min window to reduce random high/low values
* Re-Write to MQTT code, now supports multiple sensor types
**0.1.3**
* Improved error recovery, e.g. Inverter powers down overnight
**0.1.2**
* Added InfluxDB export
**0.1.1**
* Added docker image
* Added simple http web server
* Improved recovery when errors (See: SungrowModbusWebClient 0.2.6)
**0.1.0**

## Getting Started
# Local
```sh
git clone https://github.com/bohdan-s/SunGather.git
cd SunGather
pip3 install --upgrade -r requirements.txt
```
Copy config-example.py to config.py, change values as required (see comments in file)
```sh
copy config-example.py config.py
```
Run SunGather:
```sh
python3 sungather.py
```
# Docker
```sh
docker pull bohdans/sungather
docker run -v {path to}/config.yaml:/config/config.yaml -e TZ=Australia/Sydney --name sungather bohdans/sungather
```
or if using the webserver export
```sh
docker run -v {path to}/config.yaml:/config/config.yaml -e TZ=Australia/Sydney -p 8080:8080 --name sungather bohdans/sungather
```
Note: replace Australia/Sydney with relevant timezone

## Usage
See config-example.py it contains default options and comments.
If you want to use the new Energy section in Home Assistant, follow the Home Assistant setup below.
(back to top)
### Commandline Arguments
usage: python3 sungather.py [options]
Commandline arguments override any config file settings
**-c config.yaml** - Specify config file.
**-v 30** - Logging Level, 10 = Debug, 20 = Info, 30 = Warning (default), 40 = Error
**--runonce** - Run once then exit
**-h** - print this help message and exit (also --help)
Example:
```sh
python3 sungather.py -c /full/path/config.yaml
```
## Exports
A collection of exports are available:
* console: Output information to console, useful for troubleshooting
* webserver: Output to a simple website, default http://localhost:8080 or http://\:8080
* mqtt: Output to a pre-existing MQTT server, needed for Home Assistant integration
* pvoutput: Output to PVOutput.org, requires account and solar is set up on website first.
* InfluxDB: Output directly to InfluxDB, can then be used by Grafana, etc..
## Registers
This tool should be able to access most registers exposed.
Set the following in config.yaml under inverters section.
* level: 1 - This is the most useful data for day to day
* Level: 2 - This should be everything your inverter supports
* Level: 3 - This will try every register, you will get lots of 0/65535 responses for registers not supported.
* smart_meter: True - Set to true if you have a smart reader installed, this will return power usage at the meter box, without it you can not calculate house power usage.
### Useful Registers:
This is just a brief list of registers I have found useful
**daily_power_yields** - Total Power in kWh generated today
**total_power_yields** - Total Power in kWh generated since inverter install
**total_running_time** - Total Hours inverter has been powered on since install
**internal_temperature** - Internal temperature of the Inverter
**total_active_power** - Current power being generated by the inverter in Watts
**meter_power** - Power usage at the meter box, needs a smart meter installed. +ve means consuming from the grid, -ve means exporting to the grid
**load_power** - Power being consumed in total
**export_to_grid** - How much being currently exported to the grid. This is calculated from meter_power if -ve value, returned as a positive value
**import_from_grid** - How much being currently imported from grid. This is calculated from meter_power if +ve value
**timestamp** - Last time data was collected, based on Inverters clock by default

## Home Assistant setup
In the SunGather config.yaml you need to set the smart_meter if you have one;
```
smart_meter: True
```
HA sensors created by the MQTT auto-discovery;
```
sensor.inverter_active_power
sensor.inverter_daily_generation
sensor.inverter_export_to_grid
sensor.inverter_import_from_grid
sensor.inverter_load_power
sensor.inverter_meter_power
```
Put the following into your sensors.yaml
```
sensor:
- platform: integration
source: sensor.inverter_active_power
name: Solar Production (Sungather)
- platform: integration
source: sensor.inverter_export_to_grid
name: Return to Grid (Sungather)
- platform: integration
source: sensor.inverter_import_from_grid
name: Grid Consumption (Sungather)
```
The additional sensors then setup in HA are the following with Wh unit of measurement for the Energy platform.
Solar Production (Sungather)
Return to Grid (Sungather)
Grid Consumption (Sungather)
Restart Home Assistant for the sensors.yaml to be loaded.
Make sure SunGather is running, wait 5 minutes for initial data to populate.
Navigate to the Energy platform (Configuration > Energy). Add these sensors to the following areas:
Electricity Grid > Grid Consumption -> Grid Consumption (Sungather)
Electricity Grid > Return to Grid -> Return to Grid (Sungather)
Solar Panels > Solar Production -> Solar Production (Sungather)
