this is an Node for the API on the Growatt© Shine Webserver. (Shine provided by Growatt©. I'm not affiliated.)
This implementation is based on the refectured eebinterface from Growatt© Shine.
npm install growatt
This API supported debugging. you have to set the environment variable DEBUG
set DEBUG=growatt:*
set DEBUG=growatt:api
set DEBUG=growatt:verbose
set DEBUG=growatt:queue
In code: there are the following functions:
setDebugApi
| Parameter | Type | Default | Description |
|---|---|---|---|
| enable | boolean | "true" enables API debugging, "false" disables all debugging |
setDebugVerbose
| Parameter | Type | Default | Description |
|---|---|---|---|
| enable | boolean | "true" enables API and Verbose debugging, "false" disables all debugging |
"use strict"
const api = require('growatt')
api.setDebugApi(true);
or
"use strict"
const api = require('growatt')
api.setDebugVerbose(true); //
...
api.setDebugApi(false); //All debug is always turned off. So it's similar to api.setDebugVerbose(false)
This NODE-Implementation works with promise.
Understanding javascript promises
Modern Asynchronous JavaScript with Async and Await
"use strict"
const api = require('growatt')
const user="xxx"
const passwort="xx"
const options={}
async function test() {
const growatt = new api({})
let login = await growatt.login(user,passwort).catch(e => {console.log(e)})
console.log('login:',login)
let getAllPlantData = await growatt.getAllPlantData(options).catch(e => {console.log(e)})
console.log('getAllPlatData:',JSON.stringify(getAllPlantData,null,' '));
let logout = await growatt.logout().catch(e => {console.log(e)})
console.log('logout:',logout)
}
test()
Please note that you have to create an instance since version 0.2.0.
| Parameter | Type | Default | Description |
|---|---|---|---|
| config | Object | See below | Controls the processing |
The constructor has a config object as parameter. This is optional.
| config | Type | Default | Description |
|---|---|---|---|
| server | String | 'https://server.growatt.com' | The Growatt server |
| indexCandI | Boolean | false | Set to true if your Growatt page Plant is a C&I Plant page with indexbC or plantDo in the Path from the Growatt webinterface. |
| timeout | Integer | 5000 | Session timeout in ms. |
| headers | Object | {} | custom header like {'X-Custom-Header': 'foobar'}. |
| lifeSignCallback | function | undefined | Called before each Axios call. |
const api = require('growatt')
const growatt = new api()
There are several options for logging in:
| Parameter | Type | Default | Description |
|---|---|---|---|
| user | String | - | The username |
| passord | String | - | The password |
let login = await growatt.login(user,passwort).catch(e => {console.log(e)})
With resolve, the response from the website is returned.
Usually the object: { result: 1, msg: 'OK' }
With reject an exception is thrown which contains the error object with result less then 1.
| Parameter | Type | Default | Description |
|---|---|---|---|
| key | String | - | The key |
You can get the key by having an email sent to you on the Grwatt website for a third party to display the data. The key is the combination of numbers and letters in the link. It has 96 characters.
let login = await growatt.sharePlantLogin(key).catch(e => {console.log(e)})
With resolve, the response from the website is returned.
Usually the object: { result: 1, msg: 'OK' }
With reject an exception is thrown which contains the error object with result less then 1.
| Parameter | Type | Default | Description |
|---|---|---|---|
This plugin is intended for testing. On the Growatt page you can view the data from many systems. The problem is that the ID of the system is different here every time you login.
I needed it so that I could see how the messages to the different inverters are structured.
let login = await growatt.demoLogin().catch(e => {console.log(e)})
| Parameter | Type | Default | Description |
|---|---|---|---|
| option | Object | See below | Controls the processing |
This function knows the individual types of the inverter and calls up the data.
This function can be controlled via an option so that you don't always have to call up all the data that is possible:
| Option | Type | Default | Description |
|---|---|---|---|
| plantData | Boolean | true | True calls the description dataset of the plant. |
| deviceData | Boolean | true | True calls the description dataset of the plantdevice. |
| weather | Boolean | true | True calls the weather dataset of the plant. |
| faultlog | Boolean | false | True retrieves the plant's fault logs. An array with the most recent event first is returned. |
| faultlogdate | String | 'YYYY' | It is only taken into account if faultlog is true. It must be a string with the date in 'YYYY', 'YYYY-MM', 'YYYY-MM-DD'. |
| faultlogdateindex | Boolean | true | It is only taken into account if faultlog is true. The array is converted into timestampsobjects. |
| plantId | Integer | undefined | The ID of a plant. So that the output can be restricted. Attention, the ID is constantly changing on demologin. |
| totalData | Boolean | true | Retrieves the data integrals. The sums since start time. |
| statusData | Boolean | true | This is not available for all systems. Here, the current operating status, fuel injection, battery charge and generation is called up. However, the data is also contained in historyLast. |
| deviceTyp | Boolean | false | Add the device type to the Output. |
| historyLast | Boolean | true | The last data record from the system history table is called up here. |
| historyAll | Boolean | false | All data records from the system history table is called up here. |
| historyLastStartDate | new Date() | yesterday | The start time for retrieving the history. |
| historyLastEndDate | new Date() | tomorrow | The end time for retrieving the history. |
| historyStart | Integer | 0 | The server does not send all data for the time range. With the starting index you get the next rows. |
After waiting to log in with await. Can the data be retrieved using this method. In response, an object comes out that contains the data of the length.
options = {plantData:false,deviceData:true,deviceTyp:true,weather:false,chartLastArray:true}
let getAllPlantData = await growatt.getAllPlantData(options).catch(e => {console.log(e)})
console.log('getAllPlatData:',JSON.stringify(getAllPlantData,null,' '));
After retrieving the data, you should log out of the page again. It is the same call for all three login variants.
let logout = await growatt.logout().catch(e => {console.log(e)})
It is also possible to have the connection open and to check whether the API is still connected.
if (growatt.isConnected()) {
}

With some inverters, it is not always possible to read the data due to the connection via RS232. If a process is in progress, the second query is rejected. Therefore, the requests are placed in a queue and processed sequentially. If the inverter does not send any data but reports success, the request is repeated.
// Growatt must be connected
const allPlantData = await growatt.getAllPlantData(options).catch(e => {console.log(e);});
console.log('Fatched all Data');
if (allPlantData) {
let a = allPlantData[Object.keys(allPlantData)[0]].devices;
let sn = Object.keys(a)[0];
let type = a[sn].growattType;
let com = growatt.getInverterCommunication (type);
console.log(com);
let run = []
Object.keys(com).forEach(name => {
if (com[name].subRead) {
com[name].subRead.forEach(name => {
run.push(Growatt.getInverterSetting(type, name, sn)
.then(r => {
console.log(name,r);
})
.catch(e => {
console.log(name,e);
}))})
}
if (!com[name].isSubread) {

- Click on attachment below
- Top right +, then list data loggers
- Click on existing data logger
- Configure data logger
- Wireless hotspot mode
- Put the stick in AP mode
- Connect to Wifi hotspot, PW 123456789 ? <- check again
- Continue
- Advanced
- Time setting
- Interval to 1
- Enter password growattYYYYMMDD (e.g.growatt20220209)
