Dave, Node red is an amazingly flexible GUI package once through the worst of the learning curve, attached is my effort so far.? I'm sure QRP will be fine with the ESP8266, I tried multiple shielding ideas with the ESP32 but needed external antenna so the RF probably got in that way and high pass filters for 2.4Ghz became too much trouble.? I'm also not sure that all of the ESP products available on line are created equally
