I keep a stockpile of cheap ESP32 and ESP8266s at home, and any time I need something "ensmartened" (opposite of enshittified?) I grab whichever one is appropriate, solder up what I need, design/3D print a case, flash it from my _other_ laptop which has Chrome on because Firefox doesn't support WebUSB :'(, and it'll show up in Home Assistant for adoption the moment it lands on my IoT WiFi network.
