Les donn\u00e9es peuvent \u00eatre affich\u00e9es directement sur la plateforme Ewattchcloud. Pour ce faire, la table modbus doit respecter un format.
\nUn outil en ligne est disponible ici<\/a>. Il permet d’obtenir le mod\u00e8le de table modbus \u00e0 suivre en fonction des donn\u00e9es n\u00e9cessaires.<\/p>\n
