Problem solved, thank you very much! I have some doubts regarding my project. I want to collect data from the sensors of a house (thermostat, presence sensors, etc...) with a PLC S-1200. I want to be able to store these data in the cloud, visualize them and modify them through any device connected to the network, thanks to an IOT2040 and Node-Red. But I think my problem is that I don't understand very well what each device does and what is the mission of each one. The PLC yes, but the IOT I do not know if it is responsible for connecting the data with cloud and interact with them through MQTT which in turn is implemented in Node-RED, am I right? When I put the MQTT node, in the server option, I have to put the IP address of the IOT or the address of a broker such as myqtthub? What is the difference between one or the other? What makes that I from another device (for example a mobile phone) connected to the same WIFI network to which the IOT is connected through the USB, allows me to enter in the dashboard of Node-Red and visualize the data? What should I do for this? What I have connected is the IOT to the PC on the X1 and the PLC to the IOT on the X2 and the USB Wifi. Best regards |

Hi, the IOT2040 is only connected directly to your PC? Or are you using a router / switch? If it was connected directly to the PC, it is obvious that another device cannot access it. Can you please post the output of the command nmcli? There is an issue, that you need to use the command line with -g flag to install nodes. I think this is somehow related to the old versions being used. Much nodes have suspended support of NodeJS 8. That mostly is the reason why installed nodes are not displayed, as they are not compatible. What command are you using to install the nodes which are not displayed? Best regards! |
Not working for IOT2050 support anymore from March 1st, 2024. |
