I am a complete newbie using Node-RED but have been working on what seemed a rather simple project for a couple of weeks now, and I am stuck. I am trying to monitor the status of a series of variables across multiple ESP32-based devices using HTTP GET. I also want to be able to send values to all or…

There are 2 ways... The HTTP request node accepts msg.url (you could build a URL in a change or function node) The URL field accepts mustache formatted values e.g. {{ip}}/path As documented in the built in help [image]

So simple.. thank you so much @Steve-Mcl for the quick reply. I will give it a try.
