Goodwe rest sensor for multiple json elements

Configuration
18

Just tried it, and all working this end.

How often does this sensor update, and is it possible to change the refresh time?

19

Nice to see it is working.

I don’t have a clue how often it updates. If I look in my grafana dashboard which shows the data that home assistant exports to influxdb, i have a data point around every 2/3 minutes for this day. If you have a clue how to control it, please let me know.

Hi there,
Nice to see this progress on a Goodwe integration.
I have also received info about native access instead of web scraping for which I’ll update the code… Soon ish

21

I’ve added in the following so i can get an update every 5mins.

import datetime
from datetime import timedelta
MIN_TIME_BETWEEN_UPDATES = timedelta(minutes=5)

Can you share the information? I have some time until Monday to work on this. :slight_smile:

23

Works awesome man! Thanks @TimmyBankers

24

I added the code in this repository (cleaned up a bit).

Also found out that the scraping interval can be configured with config setting: scan_interval, and no code changes are required.

25

I have 2 inverters but sensor is showing status only one of them :frowning:

26

@jojoro, I think the json parsing part of the code just takes the first element of a list somewhere. This means the current code only supports the first inverter. Feel free to update the code. :slight_smile:

Hello Everyone. I wish I could contribute, your work is amazing.
I am however a complete beginner. I have managed to get this working though.
Is it possible to display only some of the many attributes on the UI ?
Lets say PV voltage and current for example.

28

Hello all,
I am also very new to Home Assistant, only a few weeks.
I have also managed to get this working.
It is possible to display only some atrributes on the UI.
I use this method:
platform: template
sensors:
invertersn:
value_template: “{{ states.sensor.sems_portal.attributes.sn }}”
pvvoltage1:
value_template: “{{ states.sensor.sems_portal.attributes.vpv1 }}”
pvvoltage2:
value_template: “{{ states.sensor.sems_portal.attributes.vpv2 }}”
I don’t know if this is the correct method but it will display the attributes sn,vpv1, vpv2
I hope this will help you a little more.

Hallo Bart

Thank you very much, it work perfectly

30

Hello,
You can use also the custom:state-attribute-element to get this info out of the sensor.sems_portal
(so that it wouldn’t create a sensor for every attribute you want to show)

https://github.com/custom-cards/state-attribute-element

Kind regards,

Bart

Thanks Bart,

This works great!
Do you know if there is a way to return the value from each attribute as a number rather than as a text string?

I’d like to be able to graph the output over a period of time.

Just create a sensor.
See below for my implementation (the spellingmistakes are intentional!)

Issues after upgrading to 0.92? See here: https://github.com/TimSoethout/goodwe-sems-home-assistant/issues/3

34

Did this work for you? I cant get it working. Could you possible share you files?

35

I see I made a small typing mistake, the first needed { is not shown, sorry about that.

{
  "domain": "sems",
  "name": "Goodwe SEMS scraper",
  "documentation": "https://github.com/TimSoethout/goodwe-sems-home-assistant",
  "dependencies": [],
  "codeowners": [],
  "requirements": []
}

The issue-text on github has also been corrected.

36

Thanks, I had already added the { but I also made a typo I now corrected. It’s working again.

37

Any plans to change this from a scraper to a REST API call?
Documentation:
http://au.sems.com.cn:82/swagger/ui/index

E.g.

curl -X POST --header 'Accept: application/json' --header 'token: {"uid": "[redacted]","timestamp": 1558143769193,"token": "[redacted]","client": "web","version": "","language": "en-GB" }' 'http://au.semsportal.com:82/api/v2/Common/GetApis'
