Idées pour compteurs avec node red

un compteur avec remise à zéro, A adapter ….

Nota : cette variable est seulement connue dans le flux , ce n'est pas une variable globale ni persistante …mais je pense que c'est possible de le faire

fonction.js

var compteur1 = flow.get("compteur1") || 0
compteur1++
if (compteur1 === 6)// remise à zero à 6
{
compteur1 = 0;
}
flow.set("compteur1",compteur1)
msg.payload = compteur1
return msg;
