Problems to connect to Gardena cloud service with the Gardena binding

bodow · May 13, 2021, 4:31pm

I am on openhab 3.0.2. I find this entry in openhab.log every 10 seconds (10 seconds are my timeout setting for the Gardena binding):

2021-05-13 18:21:45.342 [WARN ] [ternal.handler.GardenaAccountHandler] - Error 429 null, {"message":"Limit Exceeded"}

I discovered it today, but my logfiles show it starting from April 30th. Maybe it started earlier, but older logfiles are deleted. The binding configuration was working before with openhab 3.0.1 and since then it has been unchanged.

Additionally the “Gardena Smart Home Account” item is in state “ERROR:COMM”. What can I do to successfully connect to the Gardena cloud service again?

I found out myself:
I created a new API-Key at this website: https://developer.husqvarnagroup.cloud/
Let’s see, if that’s a temporary solution.

After 23 days I had to renew the API-Key again. It looks, that there is a limit within the Husquana cloud service, that is reached after some events and that triggers blacklisting the API key. At this point of time I couldn’t determine the limit value.

I have five Gardena devices in operation:

one mower
three water control valves
one smart sensor

Maybe the number of devices has an effect on reaching the limit.

After a larger number of entries “Connection Lost” in the log these entries follow, which relate to the limit:

The authentication information in these log entries is anonymized and the clientId is invalidated.

I appreciate any hint to avoid reaching this limit which stops the operation of the binding and requires manual intervention (creation of a new API key).

3,000 a month.
That’s about one every fifteen minutes.
It also says it’ll throttle you to one every 15 minutes anyway, i.e. discard or reject more frequent calls.

The binding doesn’t seem to offer you any control over that rate.

Hi,
I am experiencing the same problem. Periodically, I am loosing connection to Gardena cloud,

This behaviour started with the new binding in 2020. I am on OpenHABian 3.0.2 on Raspberry 4. After some time, Gardena blocks my access. Any idea?

michel53 · June 25, 2021, 8:17am

Now I have the same problem. Gardena Thing is offline, “limit exceeded”.
Restart of OH does not help.
Access via Gardena app is possible without problems.

bodow · June 25, 2021, 12:55pm

For me the creation of a new API key worked around the problem temporarily.

Anyway in the meantime I issued a GitHub ticket: [gardena] Binding shouldn't reach request limit on Husqvarna cloud service · Issue #10841 · openhab/openhab-addons · GitHub

Juergen_Pechmann · June 25, 2021, 1:13pm

Same issue , communication stop after around 20 days and I have to create a new API-Key.

OH-3.0.2 on Pi-4

michel53 · June 25, 2021, 3:48pm

Yes, after creating a new API-key, it works again.
Let’s see how long…

tknaller · July 15, 2021, 1:53pm

same here… openhab 3.1.0 release

rossko57 · July 15, 2021, 3:08pm

That’s good then, you’re all working fine with a new key.

winsi · August 1, 2021, 3:33pm

Hello,
Even if i renew the API, it connects but after one minute, i have “connection lost”

In the log i have :

 2021-08-01 17:31:44.449 [WARN ] [rdena.internal.GardenaSmartWebSocket] - Gardena Webservice error (gardenabridge-My Garden): java.util.concurrent.TimeoutException: Idle timeout expired: 150000/150000 ms, restarting

2021-08-01 17:31:44.451 [WARN ] [.core.thing.binding.BaseThingHandler] - Handler GardenaAccountHandler tried updating the thing status although the handler was already disposed.

Somebody have an idea ?

Cplant · October 31, 2021, 9:05pm

Thanks, this helped me as well.

jwsp1 · March 15, 2022, 10:38pm

There is a new github issue with a possible explanation for the connection issues. Something with the service_id could be wrong.
Link to the issue: [gardena] Error 400 Bad Request - Can not parse service ID · Issue #12481 · openhab/openhab-addons · GitHub

Hope somebody can fix this. For the meantime, downgrading to openHAB 2 and installing the “new” binding for openHAB3 (Link: Gardena API Binding | Eclipse Plugins, Bundles and Products - Eclipse Marketplace) works for me.

openschwall · June 15, 2022, 7:48pm

Hi, I had to get a new API key from the developer site. The procedure to get it has been changed and the documention of the OpenHAB Gardena binding seems to be obsolete.
Now, the site https://developer.husqvarnagroup.cloud now asks for “Redirect URLs”. I entered “http://localhost:8080” and tried some other URLs with no success. The Gardena binding cannot connect to the Husquvaran / Gardena cloud.

What can I do? Any hint greatly appreciated.

Peter

openschwall · June 16, 2022, 9:29am

I would like to point out that due to the change (I think API version has changed to v1.1) in the developer portal now asking for Redirect URLs new users of the Gardena binding cannot use the binding as long they do not supply a proper “Redirect URL”.
In my opinion, this renders OpenHAB’s Gardena binding useless when we do not find a solution for “Redirect URL”.

Any help / hint welcome!

bodow · June 17, 2022, 12:00pm

First of all I am not the developer of the Gardena binding and I haven’t checked its code. I am not an expert of the Gardena API either. This means, that I can only make assumptions here. The binding has been deveoped and maintained by @gerrieg and he probably can explain better.

Currently the Gardena binding works at my site. All my Gardena things are online. I haven’t entered a redirect URL when I created a new API key some weeks ago. The site https://developer.husqvarnagroup.cloud hadn’t asked me for a redirect URL at that time. When I enter this site today, the URL “http://localhost:8080” is displayed in the upper left corner of the screen. This means, thta there must be a way to make it work without a valid redirectUrl.

The Gardena API is documented here. The README doesn’t list major modifications from V1.0 to V1.1. Husqvarna writes, that they want the clients of that API to use webhooks instead of websockets. They hope to lower the load on their service with webhooks. The webhooks require a listener on the client side to receive messages. I believe, this mechanism isn’t used by the current Gardena binding and I completely agree on that for security reasons. May the redirectURL be needed for those clients of the API only, that use webhooks?

openschwall · June 17, 2022, 6:45pm

Bodo, thank you for your detailed analysis.

In fact, everything is fine for “legacy” users as for me until one week ago. Then, I had to get a new API key from the developer’s site and suddently found the new entry “Redirect URLs”. Using “http://localhost:8080” as input I was able to get the APIkey in the usual manner. However, my openHAB cannot connect to the cloud using this key, producing an error " COMMUNICATION_ERROR Error 400 Bad Request, {“error”:“invalid_client”,“error_description”:“Client not found”,“error_code”:“client.not.found”}.
For 2 years I did no encounter any problems to connect so I assume entering “http://localhost:8080” as Redirect URL could be wrong and I am stil looking for a solution.

Edit:
“When I enter this site today, the URL “http://localhost:8080” is displayed in the upper left corner of the screen.” Do you mean this is in your brower?

“This means, thta there must be a way to make it work without a valid redirectUrl.” Sorry, I do not understand that.

Regards

Yasir_K · June 17, 2022, 8:42pm

I’m having similar issues today. Looks like the API has changed completely:

Gardena expects: a client ID and secret whereas the binding is sending a user/pass and grant type that is not supported

Gardena documentation:

curl -X POST -d “grant_type=client_credentials&client_id=626b4ecc-9b26-4f41-991f-bfdbaf94cc12&client_secret=xxxxxxxxxxxxxxxxxxxxx” https://api.authentication.husqvarnagroup.dev/v1/oauth2/token

Whereas the binding is sending:

https://api.authentication.husqvarnagroup.dev/v1/oauth2 /token, data: {“caseSensitive”:false,“fields”:{“client_id”:{“name”:“client_id”,“values”:[“626b4ecc-9b26-4f41-991f-bfdbaf94cc12” ]},“grant_type”:{“name”:“grant_type”,“values”:[“password”]},“username”:{“name”:“username”,“values”:[“tXxxxxxxxxxxxxxxx”] },“password”:{“name”:“password”,“values”:[“xxxxxxxxx”]}}}

openschwall · June 22, 2022, 7:16am

Husqvarna API has been changed, so for all users which need new credentials the binding is broken. Obviously, API now requires API key AND secret. @gerrieg do you have time for a look at it?

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.
