bonjours a tous,
quand je j'appuie sur A puis sur B ma variable "compteur" ne s'incremente pas
alors que dans l'autre sens (B puis A) mon "compteur" monte
quelqu'un pourrais me dire comment faire pour que ça monte peut importe le sens d'appuie
merci de votre aide

Hello everyone,
when I press A then B my variable "counter" does not increment
while in the other direction (B then A) my "counter" goes up
someone could tell me how to make it go up no matter what sense of support
Thank you for your help

Your problem is that the join is putting the msgs into the msg.payload array based on the order they arrive, while your function is expecting msg A to always be the first msg in the array. Instead, try creating a key:value object. Here is your flow setup that way.
====
Votre problème est que la jointure place les msgs dans le tableau msg.payload en fonction de l'ordre dans lequel ils arrivent, tandis que votre fonction s'attend à ce que le msg A soit toujours le premier msg du tableau. Essayez plutôt de créer un objet clé: valeur. Voici votre configuration de flux de cette façon.
