Hello everyone, this may sound like a dumb question but I am very new to node-red and was wondering if you had any thoughts on this.
I am running node-red from a main Windows device. I have multiple pi devices that I would like to listen for keystrokes and have it displayed in my node-red dashboard. That is the primary goal and was wondering if you had thoughts or suggestions on what to do.
So far, I have seen that to get messages from pi devices, the best way is to use MQTT to send messages out and then have node-red receive them with the MQTT module. Still not sure how the keystrokes would be sent through an established MQTT. Is this the best method or is there something else that’s better? I think once I get the keystrokes received in node-red then I can handle the display of it via changing a label’s variable to equal the payload, but it’s the steps in between where I am stuck.
Thank you in advance
