Warema WMS and Home Assistant

[Stephan1908]

Hello Mr. Mund, In my house, I used the Warema WMS system with 3 shutters and 7 external blinds. I would like to integrate the WMS system into my Home Assistant system. I can't find anything on the internet, but today I found your example in Python. Can you tell me if it works with Home Assistant? Then I would buy the Warema WMS WebControl web server. Do you have any tips for me? I'm unfortunately a beginner in terms of integrating and especially Python. Sincerely yours Stephan from Germany :-)

[cornim]

Sorry, I didn't see this earlier. Yes it works with home assistant and I even have an integration for it. Best

[cornim]

It only supports vertical blinds right now, though, as I don't own anything else.

[Stephan1908]

Hi, thanks for the answer. I have bought a webcontrol and will test it soon. I hope I can do it. greetings

[Stephan1908]

Hi, so, I've tried a lot now, but unfortunately I'm not getting anywhere. I have copied the python files (shade, init and wms_controller) into my Python scripts folder. after restarting home assistant I get the services from developer tools. If I enter the following into service data:

self.wms_ctrl: wms_ctrl self.room: children's room self.channel: children's room self.time_between_cmds: 1 self.num_retries: 3 self.position: 50 self.is_moving: is_moving self.state_last_updated: None

Nothing happens. can you tell me what i did wrong? My WebControl server is under http://webcontrol.local. Thank you very much. Greetings

[cornim]

Hi, to access these scripts from home assistant you need to write an integration. https://developers.home-assistant.io/docs/creating_component_index/

[Stephan1908]

Hello Mr. Mund, I tried to create an integration, but I can't do it. I'm not fit for it. Can you maybe help me with the integration? I have the Hello_state.world integration from the link above. If I copy the files from you into the folder config\custom_components\warema_wms and make the call in my Configuration.yaml (warema_wms:) I get the following error message: Component error: warema_wms - Integration 'warema_wms' not found. Many Thanks. Greetings Stephan

[cornim]

Yes, I can help. I'll upload my integration to GitHub in the next weeks and then post the link here so you can use it.

[cornim]

I uploaded the integration here https://github.com/cornim/ha-warema-integration

[Stephan1908]

Hi, thank you very much. I copied the folder warema_wms_webcontrol to \config\custom_components and added warema_wms_webcontrol: to my configuration.yaml. When I check the configuration, I get an ok. When I restart Homeassistant, I get the message: The following integrations could not be set up: warema_wms_webcontrol Please check your config. I compared the integration with existing integration, but unfortunately I cannot find any connections. I think I don't have the libraries (shade.py and WmsController) in the right place (I have these in the same folder as the integration) and / or something is still missing in the configuration.yaml. Unfortunately it is very time-consuming and very complicated for me as a beginner to integrate the Warema, but I have no other solution, so I try to fight my way through here. In any case, a big thank you for the help so far. greetings

[cornim]

You have to install the warema library via pip.

pip install warema-wms-controller

[Stephan1908]

Hi, Thanks for the tip. I think I now know where my problem is. I'm using HassOS, if I've read correctly, the "pip install" command doesn't work here. I would have to set up my Home Assistant again, but not with the HassOS image, but in a virtual environment (Home Assistant Core). Greetings

[cornim]

That might be. I don't really know anything about HassOS. Best of luck.

@Stephan1908 you need to make sure to include:

you need to make sure you have this in your configuration.yaml:

python_script:

and then using the cover platform: ('warema_wms_webcontrol:' will not give you anything)

cover:

• platform: warema_wms_webcontrol webcontrol_server_addr: http://192.168.87.xx //--whatever is your webcontrol local ip update_interval: 300

you alos might want to add

logs: warema_wms_webcontrol: debug homeassistant.components.warema_wms_webcontrol: debug

for debug info.

Before restarting HA, you need to add a folder under config/custom_components, called warema_wms_webcontrol with the HA integration files from cornim

under config you need to create a folder called python_scripts (if it isn't there already) and then in that folder a new folder called warema_wms where you copy the warema_wms files from cornims core folder.

Hopefully this puts you on a working path for this.

[oywino]

Sorry to jump in so late. I too am trying to get this working and everything seems pretty much straight forward but I can't get it to run successfully. Any assistance is highly appreciated. Here's my configuration.yaml:

python_script:
  warema_wms:

cover:
  - platform: warema_wms_webcontrol
    webcontrol_server_addr: http://192.168.1.133
    update_interval: 300

Here's the content of my _config/custom_components/warema_wmswebcontrol folder:

And here's the content of my _config/python_scripts/waremawms folder:

HA report configuration as valid, but during restart I get this errors in the log:

at least at my setup it works with the following:

configuration.yaml:

python_script:

without warema_wms

cover: platform: warema_wms_webcontrol webcontrol_server_addr: http://xxx.xxx.xx.xxx update_interval: 300

send from my mobile, so indentations maybe wrong, but i think HA assists you here

config/custom_components/warema_wms_webcontrol folder looks ok for me

config/python_scripts/warema_wms folder looks suspicious the folder should look like

and in there, config/python_scripts/warema_wms/warema_wms

hope this helps cheers

[cornim]

it looks like, whatever is being returned by your web control server isn't well formed xml.

Please enable debug logging to see what is being returned from the server.

Hello Dr. @cornim - thanks for stopping by 👍 I did exactly what @thesaint1975 suggested, but it made no difference. The error messages reported during startup is as follows:

My attempt to enable debug logging is as follows:

    warema_wms: debug

Apparently, only the homeassistant.components.cover: debug resulted in anything being logged. The log can be found here: https://pastebin.com/TM5SZtYS

Please advise.

As I have guessed the response you are getting is not the expected response. You get some html page back instead of the expected xml.

Why that is I can only guess. What happens if you open the page manually. i.e.

http://<ip of you webcontrol>/protocol.xml?protocol=9000020300&_=1658223995

Maybe this helps us determine the reason behind this error.

[oywino]

What happens if you open the page manually. i.e.

http://<ip of you webcontrol>/protocol.xml?protocol=9000020300&_=1658223995

All that happens is that I get redirected to : http://192.168.1.133/system which is the same as the default opening page of the WebControl server.

[thesaint1975]

just to be sure, do you have the WebControl or the WebControl Pro Box?

[oywino]

I have the WebControl Pro box

[Pferdebockwurst]

I have the WebControl Pro box

That one doesn't work with this plugin.

[oywino]

@Pferdebockwurst - I can only assume that you are right about that. So, the question then is; Can @cornim fix that (or anyone else)? I am regretfully not a programmer myself, but I'd love to be a beta-tester 🙂

[cornim]

Since the communication protocol was reverse engineered only someone with the WebControl Pro could reverse engineer the communication with that one and extent this plugin.

[oywino]

So, even with guidance from someone with the right knowledge - such as yourself, I couldn't do it?

[cornim]

That very much depends on your proficiency with HTTP get call reengineering and Python programming. Of course I can explain to you how I did this for the WebControl but it requires at least some technical skill and it might work differently for the WebControl Pro and since I don't own one of these, I cannot have a look myself.

[oywino]

I contacted Warema and inquired about API information. Still waiting. Has anyone else tried to contact them? Do we know their attitude with regards to third party integrations?

[Pferdebockwurst]

I once mailed them about that topic. My mail got right to the developer who posted at the homee forums (because they have produced a homee cube to integrate it in that ecosystem). Never got a response. Please keep us updated, if you get a response.

[oywino]

My mail got right to the developer who posted at the homee forums (because they have produced a homee cube to integrate it in that ecosystem)

Do you have a link to the post on the Homee Forum? If they have published an API for the Homee, wouldn't it be possible to use that also for HA ?

Homee is not open source.

Edit: I don't remember the exact forum posts, but look at this thread in the homee forums: https://community.hom.ee/t/warema-wms-cube/34917/25

WAREMA_Stefan was the guy I mailed to.

[oywino]

Coming back to this issue - trying to figure out how to reverse engineer the WMS Web Control Pro. I tried using Cordova but the data from the controller seems to be heavily encrypted and couldn't be read. I also talked to a Warema representative, and they have no plans to release any info about the API. It is sad that this company thinks an open attitude will hurt sales. Cause it won't. Quite the contrary. If decided to cooperate with the commmunity, thay would most likely see sales go up significantly. As it is now, I cannot recommend Warema to anyone with a Home Assistant installation.

[ColomboEnterprise]

Hi, i try to integrate my WMS installation i have the normal old Box and usb stick. Only Shutters are in the webcontrol I have add in the config file:

` python_script:

cover: platform: warema_wms_webcontrol webcontrol_server_addr: http://192.168.178.50

update_interval: 300

warema_wms_webcontrol: debug homeassistant.components.warema_wms_webcontrol: debug ` But get the message after reboot: The warema_wms_webcontrol integration does not support configuration via a YAML file.

I have copy and created all the files from: thesaint1975 Download from GitHub: warema-wms-controller-0.2.4 wms_webcontrol-master and installed manually.

Someone know what is missing?
