ESP32 WiFi Superstitions

The ESP32 is a popular microcontroller to use for do-it-yourself home automation, sensors, and a variety of other bits and bobs that you might want to take care of around the house. It’s the successor to the venerable ESP8266 which has found its way into many of our WiFi connected devices (seriously, open up a device and chances are relatively large that you’ll find one).
After having done quite a few projects based on the ESP32 in the Arduino and esp-idf frameworks I did start to notice some pecularities with my deployed devices (fancy wording for the one in my electrical cabinet that’s supposed to send the electrical usage data somewhere and a hodgepodge of sensor boards around the house, mostly the excellent Snuffelaar by Sebastius with firmware written by Juerd).
