H-WASHER 500 - Error while trying to get /commands/v1/retrieve

[alexandre-leites]

I was trying to use the HA addon with my washing machine (HDQ 496AMBS/1-S). However it did not work. While I was trying to debug, I downloaded this library code and found that the following call is not working.

GET /commands/v1/retrieve

The Result is:

{
    "error": {
        "message": "Invalid dictionaryId",
        "code": "RC_MDI",
        "statusCode": 400
    }
}

I tried and successfully replicated the error with Postman. However, even if I add a param named dictionaryId from my appliance info, it still not work properly.

This is my GET /commands/v1/appliance call

Any ideas how to debug or fix this issue?

Hi, for my washing machine, it returns a dictionaryId on /commands/v1/retrieve.

{
  "payload": {
    "applianceModel": ...
    "resultCode": "0",
    "settings": ...
    "pauseProgram": ...
    "resumeProgram": ...
    "stopProgram": ...
    "startProgram": ...
    "options": ...
    "dictionaryId": 150
  },
  "authInfo": {}
}

But I have no idea what your error message means, maybe the app works different for your machine and retrieving commands works in another way. But maybe it's just a missing parameter.

Unfortunately, I can't help you to debug this, the api only allows to request information about personal registered models.

I think you need to study the communication between the app and the hOn servers. I used a MITM proxy (HTTP Toolkit), but it's a bit complicated to setup, you need a rooted phone. Let me know if you have any questions about this 🙂

I'll try to intercept the requests and get back to you as soon as I get more info. Thanks

Hello,

I created the PR #2 for fixing this issue as I tested locally. Hope you can accept it and release the library version

[Andre0512]

Hi, awesome! Thanks for your contribution 😃
I created a new release for pyhOn and hon, hope you can use it now.
