Node-Red Examples

[blueskytod]

great job , i have several esp 8266 working together with this data relay system but i didn't know how to visualize data in node red , can anyone share a working flow for that ?

Thanks, I appreciate you trying it out!
Here are two examples from a project that I haven't used in a while. I've added the possibility to connect via serial or MQTT, just delete whichever node you don't use. First is the basic usage, second is the full setup that feeds into charts on a dashboard. Here is a little more about that project.
