Automower Husqvarna

openhab_knx · July 16, 2022, 6:52pm

Hi everyone,

i would again need some hints out of the community.
Currently im am struggeling with the Automower binding.

I did the registration of the application + link of API and automower connect as described in the documentation. Added the Application Key + Email/PW in the binding to create the bridge but always facing:

grant type password to URL https://api.authentication.husqvarnagroup.dev/v1/oauth2/token failed with error code unauthorized_client, description Unauthorized client: grant_type is invalid

If i try manually with curl as posted in some other topics i can successfully get the mower ID. Currently i have no clue what is wrong.

Maybe someone can give me a hint. Thank you!

[Automower] Binding does not work due to change in Husqvarna API Authentication

bug

The Automower Connect API Authentication does not work anymore as they moved to …a new authentication method. (AppKey and AppSecret). Example of the new API: `curl -X POST -d "grant_type=client_credentials&client_id=XXX_Application_Key_XXX&client_secret=XXX_Applications_Secret_XXX" https://api.authentication.husqvarnagroup.dev/v1/oauth2/token` Apparently many/all(?) users are affected: https://community.openhab.org/t/automower-binding-g2/2854/102 ## Expected Behavior The Autower Addon should use the supported authentication method. ## Current Behavior The Automower Addon does not use a supported authentication method and the connectivity fails and no bridge can be configured successfully. ## Possible Solution Add a field for App Secret and change the Authentication method. Working example: `curl -X POST -d "grant_type=client_credentials&client_id=XXX_Application_Key_XXX&client_secret=XXX_Applications_Secret_XXX" https://api.authentication.husqvarnagroup.dev/v1/oauth2/token` ## Steps to Reproduce (for Bugs) 1. Create a new Automower Bridge 2. Use Valid credentials + Valid API Key 3. Bridge does not work and error from Husqvarna API is being logged > 2022-06-20 22:16:28.815 [ERROR] [oauth2client.internal.OAuthConnector] - grant type password to URL > https://api.authentication.husqvarnagroup.dev/v1/oauth2/token failed with error code unauthorized_client, description Unauthorized client: `grant_type` is invalid > 2022-06-20 22:16:28.824 [WARN ] [ternal.bridge.AutomowerBridgeHandler] - Unable to fetch automowers: Rest call failed: statusCode=-1, message=Unable to authenticate > 2022-06-20 23:16:29.134 [ERROR] [oauth2client.internal.OAuthConnector] - grant type password to URL https://api.authentication.husqvarnagroup.dev/v1/oauth2/token failed with error code unauthorized_client, description Unauthorized client: `grant_type` is invalid ## Your Environment Using OpenHAB 3.2.0 but also tried the development branch on Github of the openhab-addons (=3.3.0 afaik) with a fresh OpenHAB 3.3.0 installation from the website. ## Notes I tried to fix it myself but I couldn't get it to work with the OAuth Implementation provided by OpenHAB (the extension uses the built-in OAuth service) as I could not get it to change the grant_type. If there are any pointers how this could be achieved without rolling a new OAuth implementation myself, I'm happy to try to contribute. I am unsure if the 'old' username/password combination needs to be removed or if it needs to stay there for compatibility reasons.

Hi.
I try the new version of the bindings but I still have the same interface with Username and Password.
I already made a clear-cache and restart but still.

Here is the configuration windows I have :

Thanks in advance for your help.

Hey!

Please first uninstall the “official” automower binding (from settings|binding) and then copy the provided jar above to addons folder.

Also, just in case, remove existing automower connect bridge and enter your app key&secret (you should see something as below):

At the end, please make sure to update bridge within your automowers (parent pbridge) so they use the newly added bridge.

That should do it. Please let me know how it goes.

Looks like I had download an old JAR. Don’t know.
Anyway all is ok now.
Many thanks for your help.
