Hola everyone!
I'm curious if anyone has been able to get Node-RED to ping their microcontroller to get the values of a port? I assume this would be through TCP like the BruControl software, but I can't seem to send the requested port data (or get the ESP32 to send a value back, rather).
I have an ESP32 with temp probes, pressure sensors, Tilt connection, pressure release, and heat/cool controls. I've succeeded in sending BruControl's global variable data to Brewfather's custom stream, but I can only send my globals there; I don't have my sensor data stored to globals (seems excessive). I'm interested in having Node-RED ping the ESP through TCP to get some value from a port (33 in my case, for pressure), get a value for a port, do whatever conversions, then send that data to Brewfather.
Any guidance on a Node-Red flow to just get data from the ESP would be helpful, as well as any information regarding data conversion (buffer to number or whathaveyou).
Thanks!

Hi there. We don't publish the protocol between the application and the interface. If you want to exchange data to Node-Red, please access it via the application.
Yeah, as I thought about it more today, I realized it wouldn't make sense for easy communication (for several reasons). All good, I just scripted a few globals for pressure and beer temp to then forward on to Brewfather. Thanks!
