Feature Request: Sensor for voltage of ESP

[OttoWinter]

Jep will take a look at that. Only need to figure out what unit the value of that is in...

Thnx! You couldn't be much faster....

There's a note in the docs:

ESP.getVcc() may be used to measure supply voltage. ESP needs to reconfigure the ADC at startup in order for this feature to be available. Add the following line to the top of your sketch to use getVcc:

ADC_MODE(ADC_VCC);

Is that still WIP?

I don't really understand your question I think, but see https://esphomelib.com/esphomeyaml/components/sensor/adc.html#esp8266-measuring-vcc

Ahh, that was the bit that I was missing! I saw esphome/esphome-core@a2b7058 but was wondering where the ADC_MODE call was at. Sorry!
