Tim,
Bedankt voor je script,
Ik heb denk ik de files gecopieerd maar bij toepassing start sems niet en krijg ik de opmerking dat config flow niet te openen is.
Doe ik iets fout?

The version key is required from Home Assistant version 2021.6. Is there going te be an update for this matter?

You are using a custom integration for sems which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant.
19:15:36 – loader.py (WARNING)

But working perfectly - Thank you for you works

FYI, the sensors should now be in its own directory, with the name sensor.py

So, for the sems sensor:
../custom_components/sems/sensor.py

Hello, I have installed this component in Hassio and the data is not updated, only if I restart Hassio makes a new reading of the data. regards

I have tried to use the available entities that are recognised by the new HA energy function but all sensors/entities are not available/recognised?

After the update of HA to 2021.8 and SEMS to 3.3 the attributes are not available anymore. One entity is available (sensor.inverter_none_energy) with the state for 'total generation' and the following attributes:
state_class
last_reset
unit_of_measurement
friendly_name
device_class

Non of the other values are available anymore

Hey guys,

Looking for some help. I installed the integration and I'm getting current power generation and total power generated however how can I get the information for daily generation onto my overview page?

I'm a bit of a noob so please be gentle. Any help would be greatly appreciated.

Hi,

Since the latest upgrade of Home Assistant below warning is showing up in the log.

WARNING (MainThread) [homeassistant.components.sensor] Entity sensor.inverter_gw3600d_ns_energy (<class 'custom_components.sems.sensor.SemsStatisticsSensor'>) with state_class measurement has set last_reset. Setting last_reset is deprecated and will be unsupported from Home Assistant Core 2021.11. Please update your configuration if state_class is manually configured, otherwise report it to the custom component author.

Is this something I can fix?

Or does the integration need an update?

Thanks for your help.

Hey Tim,

First a big thank you for making this. I’m using it almost a year and it’s working great.

But I have a question. Home Assistant has a new Energy monitor (2021.8). And I’m using your setup to get all things that I want in Home Assistant. But i don’t see my power return in this Energy monitor. I do have it as a entity.

Do you know how I can get this now to use it in the new Home Assistant Energy Monitor.
https://developers.home-assistant.io/docs/core/entity/sensor#long-term-statistics

Thanks in advance,
Marco

I am converting the custom component from Sensors -> Sems.py into Sems -> sensor.py, however when i do this, i get that Sensor_sems isnt a valid component. I am yet to upgrade to 91.4 from 90.1, as i wanted to make sure this worked before going ahead. Any help would be great!

Hi, thanks for the sensor!

When the sun goes down the PV power sensor does not go to 0 Watt, but instead hangs on the last measured value.

Great work on the addition of the Homekit sensor.
The data from this sensor in HA I have worked out from the data and comparing to my SEMS screen is the "consumption".

This sensor however is not available in the drop down box when trying to configure HA Energy.
This is also the same for trying to add any other Goodwe sensor to the HA Energy, they are not available to select to "add solar production", "add consumption" or "add return".

The Goodwe homekit has 2 CT's one reads solar production and the other reads the "feed from" or "return to" the grid.
From here consumption should just be a calculation of solar production, plus minus feed to or from the grid.
This is obviously how the SEMS portal calculates it.
I think we should be seeing 3 Homekit sensors. (From/to grid, consumption, solar production)

Not being able to add the Homekit sensor to HA is aparrantly due to the setup/coding of the sensor;
This is what HA says:
You’re configuring a statistic but you couldn’t find your source in the dropdown? That’s caused by a bug in the integration providing the entity. Integrations need to configure their entities correctly so Home Assistant knows that we need to track statistics for it and how.

Open an issue with the author of the integration and link them to https://developers.home-assistant.io/docs/core/entity/sensor#long-term-statistics.

Dear sir,
After I have updated your integrations, which worked perfectly before, I cannot use the attributes for the inverter in a card. If I open the entity, I can see the attributes like you show in the readme text.
I have changed the name in the template in configuration.yaml but nothing happens.

sensor:
- platform: template
sensors:
pv_outputpower:
value_template: '{{ states.sensor.inverter_atahualpa.attributes.outputpower }}'
unit_of_measurement: 'W'
friendly_name: "Producción de las placas"
pv_temperature:
value_template: '{{ states.sensor.inverter_atahualpa.attributes.tempperature }}'
unit_of_measurement: 'C'
friendly_name: "Temperatura de las placas"

Do you have any idea about this problem?
Thank you very much in advanced.

Hi I've just noticed some errors and the SEMS integration stopping recently. I get the following 2 errors Unable to fetch data from SEMS. 'NoneType' object is not subscriptable and Unable to fetch data from SEMS. Expecting value: line 1 column 1 (char 0). I'm running the latest code, API version. Any help would be greatly appreciated, cheers.

I've got a warning in the logging when starting Home Assistant 2021.9.2:

Entity sensor.inverter_goodwe3000_energy (<class 'custom_components.sems.sensor.SemsStatisticsSensor'>) with state_class measurement has set last_reset. Setting last_reset is deprecated and will be unsupported from Home Assistant Core 2021.11.

I think this is the change needed: https://developers.home-assistant.io/blog/2021/08/16/state_class_total/

related to #49

Since last update of home assistant (2021.9) , things seem to have changed for energy sensors.
I get below error for the SEMS sensor (also for all other energy logging sensors)

Unexpected state class
The following entities do not have the expected state class 'total_increasing'

My added attributes are not working they are all showing as unavailable, I replaced $NAME with Goodwe (Thats how it is called in Home assistant)

This is an example of the first attribute in my configuration.yaml:

sensor:
platform: template
sensors:
pv_outputpower:
value_template: '{{ states.sensor.inverter_Goodwe.attributes.outputpower }}'
unit_of_measurement: 'W'
friendly_name: "PV Power output"

Hi. I installed this integration and followed the instructions. I put my username (email), password and ID from the SEMS website, as instructed and no inverter is detected. I checked the log and it says error. Please help

While decompiling the Solargo app I found a better API that's refreshes the data more often and results in less errors

Get token:
POST /api/Solargo/Login HTTP/1.1 Host: solargo.sems.com.cn language: en Content-Type: application/json Content-Length: 74 {"sn": "_serial_of_goodwe_", "password": "_MD5_hash_of_password_"}

Geta data:
GET /api/Solargo/GetRealdataOverview?language=%22en%22&sn=_serial_of_goodwe_ HTTP/1.1 Host: solargo.sems.com.cn token: _token_ language: en

Are you willing to use this API for your HA Custom Component? If not then I will try to make my own component.

I've added some code to version 1.0.0 to read my Home Kit data. Still keep this version installed even though I migrated monitoring from Home Kit onto Iotawatt. Looked at your update yesterday but still only inverter.
Would be nice to see Home Kit too.

I can paste here entire json downloaded from account having Home Kit, probably can fork 1.0.0. and paste my messy code too.

Hi,

after reinstalling the integration since the 3.1.0 update (I think), the inverter is now exposed through a sensor called sensor.invertor_none. Previously this was sensor.sems_portal.

This looks fishy to me. I expected to see the name of my inverter as defined on the semsportal.com website (Management > Plant > Device Management > Modify. I explicitly gave my inverter a name there after observing that the sensor in home assistant reported "none" as the name.

However, I don't see the sensor being renamed...

Thanks for looking into this :)

Many thanks for the very prompt update for HA Energy. I'm guessing that the configuration of the HA Add Consumption and Return to grid might be satisfied by the inverter Seller and Buy attributes? If that's correct, is there a way to either add these manually or have them in the HACS integration so they appear in the list when you confiure these sections of HA Energy.

I started getting this error "Unable to fetch data from SEMS. list index out of range" since yesterday. Any idea what to do to fix this?

Problem:

2020-09-01 16:44:42 WARNING (MainThread) [homeassistant.util.async_] Detected I/O inside the event loop. This is causing stability issues. Please report issue to the custom component author for sems doing I/O at custom_components/sems/sensor.py, line 63: login_response = requests.post(

Fix:
Add/Wrap those calls as a job to the executor and await hem.

https://developers.home-assistant.io/docs/asyncio_working_with_async#calling-sync-functions-from-async

Please note, that the current state of this integration make Home Assistant execution halt/blocked until these calls are finished. Basically, this integration causes hiccups for the whole system now.

Looking at the error logs i think code line 105 needs editing:
response = requests.post(_PowerStationURL, headers=headers, data=data, timeout=_RequestTimeout)

Hi Tim,

Is it also possible to read out the monthly production of the solar-panels?

Hi,

I have been a long time fan of your custom integration. It has worked very well for so far but with this new upgrade i am now not able to use the new 3.1.1 version. The HACS integration upgrade went well (reinstallations also installing normally) & the HA integration removal/reinstall also seems to add normally.

However, after the HA integration is added (also if i restart HA) i get these series of errors that seems to hang up some other parts of my HA instance (both prd & dev instances behave the same) & other integrations like automations don't work normally. Also, i never see any sensors created.

These are the errors i see in my log.

Also & a perhaps an indication of something (not sure what though) i found that my sems portal web account seems to be getting 'expired' now. Until i remove the integrations & restart to stop continued setup attempts i found i could not even log on to the website with out an 'login expired' message. After the integration was removed i could once again use the sems portal website normally.

Hope this information helps you to troubleshoot thins & i am more than happy to work with you on this issue if that is of any help.

Regards
Nick Harrison

Hi
Today I update my HA to 2021.4.6 and after reboot I checked the log and saw the following errors:
homeassistant.exceptions.TemplateError: UndefinedError: 'None' has no attribute 'attributes'

and

Template variable error: 'None' has no attribute 'attributes' when rendering '{{ states.sensor.sems_portal.attributes.tempperature }}'

I must admit, I'm not sure if these errors have occurred with earlier updates as well, could be these were in it for some time.

https://www.home-assistant.io/blog/2021/03/03/release-20213/#read-more
Could you please add this? Thanks for this very nice plugin, use it with much pleasure!

Probably just something I have overlooked, but how can I update the scan interval (without readding the entity)? Its currently set to the default of 60 seconds but I would like to change it to 30 seconds. I have tried updating DEFAULT_SCAN_INTERVAL and CONF_SCAN_INTERVAL with no luck. Thanks in advance for any advice.

How to get data from second inverter?

Im trying to install the integration, both both via HACS or manual>integration the integration is not found.

What can I do wrong? Currently Im updating all to latest software

Is it possible to scrap battery level and current PV generation data?

I tried the following for the battery but it didn't work:
pv_ibattery:
value_template: '{{ states.sensor.sems_portal.attributes.ibattery }}'
unit_of_measurement: 'kWh'
friendly_name: "Battery level"

Thanks for the SEMS sensor so far! Works great!

Extra useful template - I popped the following in so that I could use it to signal if power over that being used was available:

pv_excess:
value_template: '{{ states.sensor.sems_portal.attributes.pmeter }}'
unit_of_measurement: 'W'
friendly_name: "PV spare"

Hi,

Thank you for creating this integration :)

I installed it on my HA, I've inserted my credentials, and retrieved the station ID via the URL, but HA shows two entities, 'Inverter None' and 'Inverter None Energy'. It does not show a correct name...

I'm also trying to integrate it with the new Energy menu item in the latest HA, but the net HA integration only lets me select the 'Inverter None Energy' which is the total of generated power over time, and I can't select the current generated power entity.

What am I doing wrong?

I just restarted home assistant and my energy dashboard for the day has been wiped. Best guess I have is that the last_reset state attribute of sensor.inverter_home_energy is not being updated on restart. These are the state attributes after the restart
state_class: measurement last_reset: '1970-01-01T00:00:00+00:00' unit_of_measurement: kWh friendly_name: Inverter Home Energy device_class: energy

I've installed through HACS.
Tried 3.2.0 and master. Installation seems to work. Files are available in custom components. HomeAssistant recognizes the fact that custom componen has been installed.
However, I can't add it through integrations. When I search for it, it shows no results.

I've tried the oldway of adding it through configuration.yml.
It shows the integration on the info page of homeassistant. No device or sensor shows up related to the integration.
Setting the loglevel to debug gives no additional logging output.

I noticed the last_reset attribute for the newly created energy entity does not seem to be changing. Is this as expected?

I've been using this integration for a couple weeks now and I think it's great. Thanks!

Today I noticed an error and a warning in the Home Assistant logs. Both occur quite frequently and I can't find a particular pattern.
2020-09-01 13:18:05 ERROR (SyncWorker_18) [custom_components.sems.sensor] Unable to fetch data from SEMS. HTTPSConnectionPool(host='www.semsportal.com', port=443): Read timed out. (read timeout=30)
and

I found these in Supervisor>System>System Log> Core tab. I don't experience any problems and the data from Goodwe is still updated, only sometimes delayed. Is this an error on my side or maybe a bug in the integration? I couldn't find much info online.

Extra info:

• Home Assistant installed as a VM on my ProxMox server
• Home Assistant version 0.114.4
• Goodwe SEMS integration for Home Assistant version 1.0.0 (installed with HACS)

If any extra info is needed, please let me know!

Just upgrading to 0.92 and for custom components you require a Manifest.json for each component - https://developers.home-assistant.io/docs/en/creating_integration_manifest.html

I have created one which passed the config checks, but then would completely crash HA and wouldnt reboot

After recent update via HACS the integration stopped working with Home Assistant.

It still communicates with my inverter :

But then there is an error directly in HA:

I guess the problem is here:

What can be the problem?

Hi there, thanks for writing this integration.
I have a small/tiny question:
pv_iday:
value_template: '{{ states.sensor.sems_portal.attributes.iday }}'
unit_of_measurement: '€'
friendly_name: "PV income day"
Gives an output of many many characters.
How can I format the output to say ###,## (e.g. for currency)
Thanks a mil,

                                     'gridstatus': int(res_data['gridStatus'])})

Can you please implement those attributes to sems plugin in next versions ?

I have 2 x GW5048-EM Hybrid inverters. One with a battery, the other without (for now). I would like to try and assist in getting better/more data about battery states etc. I wrote a small API to power an Android app in my house, and got some insight into how (badly) the data is displayed from the SEMS Portal.

Hi I search solution for use case, when I charge my car at night and I don't want discharge home battery. I need thru Home Assistant disconnect battery. GoodWe doesn't have this function (without change inverter mode and restart), but I think that workaround is setting DoD to 1%. DoD is possible setting only in Android application Sems Portal (no in the web interface, or iOS). Has a API available this function?

Thank you Tom

Having some troubles setting up this integration.
After importing it through HACS, and then loading it into HomeAssistant and providing all the neccesary credentials, the following error was encounted.
Unable to prepare setup for platform sems.sensor: Platform not found (cannot import name 'STATE_CLASS_MEASUREMENT' from 'homeassistant.components.sensor' (/usr/src/homeassistant/homeassistant/components/sensor/__init__.py)).

There is no homeassistant folder at /usr/src/ so the error reason is clear, however, why this is happening is less so.
Homeassistant is running as Home Assistant 2021.5.4 on a raspberry pi 4, in a docker-compose container.

Hi!

It looks like the Lastmonthetotle is showing the total amount of produced power.
Thismonthetotle seems to work without a harm. Is there a quick fix? :)
