I cloned the example template and attempted to build. Below is the output

I am able to get the project to build by making the following changes to platformio.ini

[env:esp32dev]
platform = [email protected]

lib_deps =
  https://github.com/SignalK/SensESP.git

Using the SignalK/SensESP @ >=3.0.0-beta.6,<4.0.0-alpha.1 resulted in error

.pio/libdeps/esp32dev/SensESP/src/sensesp/sensors/analog_reader.h:28:30: error: 'ADC_ATTEN_DB_12' was not declared in this scope
   adc_atten_t attenuation_ = ADC_ATTEN_DB_12;

Same as in this issue SignalK/SensESP#730

I have been stuck for months (busy at work and out of traveling) and spent hours trying to figure this same problem out. Thank goodness for seeing your posted issue. Thank you very much. Worked perfect.
