Bonjour à tous,

Après avoir passé de longues heures sur le sujet et vous avoir pas mal sollicité, je peux vous livrer le fruit de ce travail.  
Mon objectif était de pouvoir interroger les APIs tuya sans pour autan dupliquer les nœuds de la palette: "node-red-contrib-tuya-smart-device". En effet c'est dernier ne permettait pas de passer les informations d'entité par le biais d'un message.  
En m'inspirant du travail de [notenoughtech](https://github.com/notenoughtech/NodeRED-Projects/commits?author=notenoughtech), j'ai créé un subflow appelable facilement.  
Avant de vous vous parler du subflow en particulier, je vais vous fournir une liste d'action possible.

**1. Les prérequis**

Pour y arriver, j'ai dû utilisé la palette suivante pour gérer le chiffrement:

```
node-red-contrib-crypto-js-dynamic

```

**2. Le flow**

Tu devrais trouver une variable de flow avec les valeurs appelée tuya.

Salut

Tu pourrais envoyer le JSON de sortie 177 pour que qu’on y voit plus clair STP?

Par ailleurs, dit moi ce que t’as dans ton onglet «&nbsp;Context Data&nbsp;».

Bonjour,

Tout d'abord quand tu envoies du code, pense à utiliser:  
 ![image](https://forum.hacf.fr/uploads/default/original/3X/7/3/73fa2a87549dc49818dc77e99d3cbabc115d0d43.png)  
c'est plus simple à lire.

Je ne comprends pas ce qui ce passe. On dirai que la fonction n'est pas interprétée.  
Ton debug 177, il te renvoie le message complet?  
Il ne ressemble en rien à ce qui sort de la fonction chez moi.

```auto
{
"_msgid":"da882eb6a97d374b",
"time":1696470271375,
"topic":"",
"payload":"",
"headers":{
  "sign_method":"HMAC-SHA256",
  "client_id":"gs4wa87kd477esxcjunu",
  "t":"1696470271375",
  "sign":"EB6ECFA51D3563CBB21BA388B62564DA84B0F9EA25E26A1492792D130AB78C52"
  },
"url":"https://openapi.tuyaeu.com/v1.0/token?grant_type=1",
"method":"GET"
}

```

As-tu bien installé la palette: node-red-contrib-crypto-js-dynamic?  
As-tu touché au code embarqué dans les fonctions?

J'y pense maintenant (sans y croire), j'ai activé la persistance des données node-red:  
Est-ce que tu as décommenté ou ajouté ces lignes dans ton fichier mode-red/settings.js:

```auto
  contextStorage: {
    default: {
        module: "localfilesystem"
    },
    memoryOnly: {
        module: "memory"
    }
  },

```

Enfin quelle version de node-red utilises-tu? J'ai eu des souci avec la dernière sur laquelle, j'ai fait un roll back

On va finir par trouver renvoies le debug 175 et 176 que je vois quel tête ils ont.

</div>

Rehello, merci pour la réponse, oui on va y arriver.

Dans l'ordre :

1. La palette est bien installée  

2. Pas de retouche dans le code

3. Le setting.js  

4. Version Node-Red : 14.4.5, j'étais aussi revenu à l'ancienne version suite aux messages d'erreurs  

5. le debug 175 (Create signStr)

```auto
{"_msgid":"aabbc3b485eae7bd",
"time":1696487506962,
"topic":"",
"payload":"ncenrr9xhmhhxpxq3xnp1696487506962GET\ne3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855\n\n/v1.0/token?grant_type=1"}

```

1. Le debug 176 (Sign signStr with secret)

```auto
{"_msgid":"aabbc3b485eae7bd",
"time":1696487506962,
"topic":"",
"payload":"4aead8c2364754ea1ded0f14af16b9eb13d015db4df559aef0eba6410e4b3e1e"}

```

Merci.

> [@Ludoc](#):

chez moi j'ai à la sortie de la première fonction

```auto
{
"_msgid":"3b498c0ed5174fb5",
"time":1696527681551,
"topic":"",
"payload":"gs4wa87kd477esxcjunu1696527681551GET\ne3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855\n\n/v1.0/token?grant_type=1"}

```

Le seconde

```auto
{
"_msgid":"47ddc473adc2972b",
"time":1696528358156,
"topic":"",
"payload":"a2d7fa4b0668de07364fc98fd22955ab69fe0d5879f59c1a568c8aaa2e015d06"}

```

Donc le souci n'est pas le code. Tes sorties semblent être les mêmes. J'y pense est que tu as donné les droits d'accès à tes APIs sur tuya ioa  
Perso j'ai ça sur mon appli:

 ![image](https://forum.hacf.fr/uploads/default/original/3X/0/6/0696d96a5ae4c8a8e353b7980d2ae4a8df11f084.png)

Au passage contrôle les valeurs user\_id et client\_id.

Hello,  
Bon finalement j'obtiens la réponse suivante au noeud 115 :

```auto
object
_msgid: "f8892de6ad36XXXX"
time: 1696589691210
topic: ""

success: true

access-control-allow-methods: "POST, OPTIONS, GET, DELETE, PUT"

method: "GET"
statusCode: 200
responseUrl: "https://openapi.tuyaeu.com/v1.0/token?grant_type=1"
redirectList: array[0]
retry: 0

```

Ça parait correct par rapport à ton résultat du dessus.  
A un moment je me suis posé la question, "mais elle sort d'où la clé secrête ?" , du coup j'ai mis la mienne, et ça va beaucoup mieux. Comme tu disais de ne pas toucher au code, à part pour "Settings CLICK SETUP TAB", je n'avais pas cherché dedans.

Bonjour,

Je cherchais justement un code comme celui ci ! Merci a toi d’avoir pris le temps de partager.  
J’ai également une erreur du type :

14/10/2023 10:53:26[noeud: Extract Token from Response]  
«&nbsp;TypeError: Cannot read properties of undefined (reading ‹&nbsp;access\_token&nbsp;›)&nbsp;»

J’ai pourtant ajouter modifier les 3 paramètres demandés dans Settings CLICK SETUP TAB :

var client\_id = «&nbsp;wjkask3XXXXXXXXXXX&nbsp;»;  
var user\_id = «&nbsp;eu153XXXXXXXXXXXXX&nbsp;»;  
var device\_id = «&nbsp;bf8a0XXXXXXXXXXXX&nbsp;»;

et ajouter ma clé secret dans le noeud «&nbsp;Sign signStr with secret&nbsp;»

Ai-je manqué quelque chose d’autre ?

Merci à vous !

</div>

J’ai trouvé mon erreur !  
C’était dans le nœud «&nbsp;Settings CLICK SETUP TAB&nbsp;» quand on ouvre on entre nos paramètres sur le sous onglet «&nbsp;message reçu&nbsp;» alors qu’il faut évidement le mettre dans l’onglet «&nbsp;au démarrage&nbsp;» car le nœud n’est pas relié. Erreur bête. Si ca peut servir a quelqu’un.

Super en tout cas ca marche nickel merci alexb81

Bonjour,

Désolé de ne pas avoir vu ton message. Content que tu ai trouvé. Je viens d’apporter une modification sur la gestion de mes volets publiée sur un autre post. Quand j’aurais le temps de le mettre à jour, j’en profiterai pour améliorer celui-ci.

Bonne journée

Désolé, de deterrer le sujet, mais je me dois de remercier l'auteur. Apres avoir galerer avec tuya\_local de make-all, pour ouvrir mon lock de tiroir, chercher comment intégré une clé tuya, puis tuya\_ble. Rien ne fonctionnait.  
J'ai commencer a regarder tuya2mqtt, puis node red et suis tomber par hazard apres de nombreuse video incomprenhensible pour moi sur ce topic.  
Il m'a fallu 10 min pour reussir a ouvrir mon tiroir, je suis tellement content que je me devais de poster ce remerciement.  
J'ai meme reussi a ajouter un bouton pour lié home assistant et node red facilement (bon j'arrive pas encore a faire en sorte que mon bouton declenche l'inject de recuperation du token, puis l'inject d'ouverture du tiroir, mais actuellement, en déclenchant l'inject d'ouverture du tiroir, ca fonctionne) donc je suis heureux 😍  
Grand merci @alexb81  
Je vais meme voir si je peux faire pareil avec mes serrures connectées.
