So where is this PR waiting for? Why isn't this merged?

Hi, I tried your code but it was interpreted as Energy monitor :
08:43:20 RSL: SENSOR = {"Time":"2020-04-10T08:43:20","ANALOG":{"Energy":0.002,"Power":20,"Voltage":230,"Current":0.086},"ADS1115":{"A0":0,"A1":0,"A2":0,"A3":0}}

OK, I found something. The analog assignment is wrong interpreted:
06:55:47 RSL: SENSOR = {"Time":"2020-04-11T06:55:47","ADS1115":{"A0":3317,"A1":3311,"A2":3310,"A3":3312},"GP2Y10":{"Air quality":48}}

Ok, My mistake. I though that order doesn't matter:

// User selectable ADC0 functionality
enum UserSelectableAdc0 {
  ADC0_NONE,           // Not used
  ADC0_INPUT,          // Analog input
  ADC0_TEMP,           // Thermistor
  ADC0_LIGHT,          // Light sensor
  ADC0_BUTTON,         // Button
  ADC0_BUTTON_INV,
  ADC0_RANGE,          // Range
  ADC0_CT_POWER,       // Current
//  ADC0_SWITCH,         // Switch
//  ADC0_SWITCH_INV,
  ADC0_GP2Y10,         // Sharp GP2Y10XX Dust sensor
  ADC0_END };

And I change
#define XSNS_66 66
because 58 is busy now
