Domoticz GoodWe Solar Inverter plugin (SEMS API)

Domoticz GoodWe Solar Inverter plugin (SEMS API)

This plugin provides information about your GoodWe solar inverter too Domoticz. This plugin has been made by analysing requests made by the GoodWe SEMS Portal website and following the API documentation provided by GoodWe.

This plugin was created by Dylian94 (/dylian94/domoticz-GoodWeSEMS) but that version is out of maintenance. Additional credits to Mark Ruys' gw2pvo for getting the API calls right.......

Important update note (v4)

Per version 4 (November 2023), I've updated the plugin to the Domoticz Extend Framework, which means the device definition is changed. To make sure that you still have your historical sensor data, please read the wiki.

Installation and setup

Follow the Domoticz guide on Using Python Plugins. Check limitations on the bottom of the page. The following Python modules should be installed. Login to a shell:

sudo apt-get update
sudo apt-get install python3-requests

Then, go to the domoticz plugin directory and clone this repository (eith SSH, requires git account):

cd domoticz/plugins
git clone [email protected]:janjaapko/domoticz-GoodWeSEMS.git

OR

Login to a shell, go to the domoticz plugin directory and clone this repository (with https, requires no git account):

cd domoticz/plugins
git clone https://github.com/JanJaapKo/domoticz-GoodWeSEMS.git

Restart Domoticz server, you can try one of these commands (on Linux):

sudo systemctl restart domoticz.service
sudo service domoticz.sh restart

Open the Domoticz interface and go to: Setup > Hardware. You can add new Hardware add the bottom, in the list of hardware types choose for: GoodWe inverter (via SEMS portal).

Follow the instructions shown in the form.

Updating

Login to a shell, go to the plugin directory inside the domoticz plugin directory and execute git pull:

cd domoticz/plugins/domoticz-GoodWeSEMS
git pull

Current features

1. Get all stations for a specific user account
2. Automatically get data for all inverters (for one station)
3. The following devices are added to Domoticz for each inverter:

Unit	Description	Type	Remark
1	(Hardware name) - Inverter temperature (SN: (your S/N))	LaCrosse TX3
2	(Hardware name) - Inverter output current (SN: (your S/N))	Current

14	(Hardware name) - Inverter input 1 power (SN: (your S/N))	kWh	default: used. calculated in plugin
15	(Hardware name) - Inverter input 2 power (SN: (your S/N))	kWh	calculated in plugin
16	(Hardware name) - Inverter input 3 power (SN: (your S/N))	kWh	calculated in plugin
17	(Hardware name) - Inverter input 4 power (SN: (your S/N))	kWh	calculated in plugin
18	(Hardware name) - Inverter output frequency 1	Custom Sensor

There is a lot more information available trough the GoodWe API if you would like to have a specific feature added to this plugin please submit an issue as indicated in the paragraph above.

Current limitations

1. You can only fetch data for 1 powerstation (which can consist of more than 1 inverter). The field Power Station ID is now mandatory
2. The GoodWE API does not always respond in time, leading to errors like below. This is not a problem, data will be updated on the next try.

Error: Zonnepanelen: (Zonnepanelen) RequestException: HTTPSConnectionPool(host='eu.semsportal.com', port=443): Read timed out. (read timeout=10)
Error: Zonnepanelen: (Zonnepanelen) Failed to request data: Failed to call GoodWe API (too many retries)

Crash of Domoticz

Several times a day domoticz crashes.

When i look in the crash log i find:

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

The strange thing is that i first had the same problem with a Growatt inverter plugin.
I delete everything from that inverter and after 2 days it started with the Goodwe inverter plugin.

Als deleted the Goodwe plugin and downloaded a the last version. Same problem.

Any ideau what is cousing this problem?

In hardware is see 2 SemsApi types.. How do i know what is the good one or doesn't it matter which i choose.

.

Domoticz environment (please complete the following information):

• Domoticz Version: 2023.1

Battery

It would be great to see batt level (%) and batt power (W) for automation purposes

Found out on this Github-page I have to convert the database.
Followed the instructions, but on import I got a error...

--ascii Use \037 and \036 as column and row separators
--csv Use , and \n as column and row separators
--skip N Skip the first N rows of input
-v "Verbose" - increase auxiliary output
Notes:
* If TABLE does not exist, it is created. The first row of input
determines the column names.
* If neither --csv or --ascii are used, the input mode is derived
from the ".mode" output mode
* If FILE begins with "|" then it is a command that generates the
input text.

Expected behavior
That import would work as supposed

Plugin not showing

After a fresh install, according to the guide, i'm not seeing the harware being available.
Nothing in the logs either.

Any clues?

Suddenly (last weeks) a lot of connection errors

Lot of connection errors the last weeks
Error: Goodwe Solar: RequestException: HTTPSConnectionPool(host='eu.semsportal.com', port=443): Read timed out. (read timeout=5)

You already mention this in the readme.

The PHP script does not seem to have this issue https://www.domoticz.com/forum/viewtopic.php?p=292043#p292043 so perhaps it could be possible to fix?

I have your code running, installed as instructed, and seems to work.
But when you check the you see a lot of repeating errors. How to solve these errors?

Update: I see in Domoticz, that my second string is not updated...

To Reproduce
Domoticz and your code running, logging on debug. Check log of Domoticz

Expected behavior
No errors in the log.

Update of both strings...

Thank you!

Can't get it working

Hi,
I have used the older plugin before, deleted it, restarted domoticz, installed your plugin, restarted domoticz.
I entered my credentials in the Hardware tab, and now I see this in the logs:

Still not working under Bullseye

Hello,

This very nice plugin is working perfectly under Buster, but not under Bullseye.
I know it's due the Phyton version. Does anybody got this working under Bullseye?
It works in Domoticz Beta version. But I would like to use in production.

Please help me with the right instructions how to adjust Phyton to the working version under Bullseye.

Thanks!

Pieter

Transfer from old plugin to new

Actually not an issue, but my Github skills are insufficient.

In my case, I installed the original plugin (dylian94).
Now I wanted to move to this newer plugin.

I stopped domoticz, removed the old plugin folder, and followed the instructions given.

Now the new plugin runs and it is creating new devices.
To preserve the historical data I tried replace the old power generated device with the new.

This was not possible, because the old device included 'W' in it's state.

By adding this line at before the 'newCount=' as line 432, the problem was solved (in plugin.py).
previousPower = previousPower.replace("w","").replace("W","")

OLD

    #average current and previous power (Watt) and multiply by elapsed time (hour) to get Watt hour
    newCount = round(((float(previousPower) + inputPower ) / 2) * elapsedTime.total_seconds()/3600,2)
    newCounter = newCount + float(currentCount) #add the amount of energy since last update to the already logged energy
    logging.debug("Test power, previousPower: {}, currentCount: {:6.2f}, newCounter: {:6.2f}, added: {:6.2f}".format(previousPower, float(currentCount), newCounter, newCount))
    return newCounter

NEW

    #average current and previous power (Watt) and multiply by elapsed time (hour) to get Watt hour
    previousPower = previousPower.replace("w","").replace("W","")
    newCount = round(((float(previousPower) + inputPower ) / 2) * elapsedTime.total_seconds()/3600,2)
    newCounter = newCount + float(currentCount) #add the amount of energy since last update to the already logged energy
    logging.debug("Test power, previousPower: {}, currentCount: {:6.2f}, newCounter: {:6.2f}, added: {:6.2f}".format(previousPower, float(currentCount), newCounter, newCount))
    return newCounter

RFR: Make unit test work again

The current unit tests are broken.

I am working on this, will make a PR afterwards.

Clean install crashes on Bullseye

Describe the bug
Domoticz crashes completly after fatal error.

The error is caused when creating the first device.
As I am not familiar with the Domoticz plugin implementation I could not investigate any further.

To Reproduce
Steps to reproduce the behavior:

1. Clean Domoticz installation
2. git clone into plugins folder
3. Restart service
4. Add Hardware device as documented.
5. Go to Devices tab, and Domoticz has crashed.

Expected behavior
I would expect that all the devices would be visible.
