Bonjour;

Je ne sais pas comment changer l'adresse ip de mon esclave sur node-red. Pouvez vous m'expliquer comment faire.

Merci

Welcome to the forum @Ener

Are you using node-red-contrib-modbus? The slave address is configured in the modbus nodes.

Merci.  
Je suis désolé mais je ne comprends pas la question je viens tout juste de rentrer dans cette application et je suis perdu j'ai essayé de voir sur le site les commandes qu'il propose mais je n'ai rien trouver concernant cela je ne cherche peut-être pas aux bons endroits. J'ai récupéré le travail de quelqu'un d'autre sauf que depuis l'adresse Ip de l'arduino à changer et je ne sais pas du tout comment la changer et quand je lance Node-Red cela se connect directement a cette adresse ip.

1. open the node-red editor in a browser (`http://127.0.0.1:1880`)
2. press `CTRL-F` and search for `192.168.1.136`
3. double click the found node
4. change the address
5. Press the `Deploy` button.
