ESP32 soil sensor drops off wifi every few hours. Fix it in the sketch or is it my router?

   Almost always the board, not the router. The wifi library doesn't reconnect on its own in most of the example sketches. Add a check in loop: if WiFi.status() isn't connected, call WiFi.reconnect() and wait a second. Also WiFi.setSleep(false), that fixed mine.

   Could also be power. Mine dropped constantly on a cheap USB brick and was fine on a better one. Capacitive probes pull a bit when they read.

   Added the reconnect and it came back on its own last night, so calling it half fixed. Will swap the brick and see if the drops stop entirely.
