   1. WiFi radio begin() will fail and system reboots

   2. second connect will pass

   3. sequence fails again after deep sleep and timer WAKE

Long term TODO:

•  Hall Effect sensor based wind and rainfall measurement
•  I2C based wind counter, easier to periodically read instantaneous wind values with ULP
•  Layout ESP32 on main PCB, get rid of the dev module entirely
•  Really attack the deep sleep current support
•  Add FET switch for powering down all peripherals while in deep sleep
•  No power LED constantly drawing current
•  LoRaWAN stack
•
