Posted this once already....not sure what happened to that post. Posting again...
using the circuit layout and battery code from https://learn.adafruit.com/adafruit-feather-huzzah-esp8266/power-management. In the section called "Measuring Battery"
The RAW values coming back from my huzzah feather..started at 182...go down to 2 ...then go back up to over 200+. Don't see how that is supposed to map to some decreasing battery level after mapping the range to 0 to 100.
My project is using a 3.7V 1200mAh lipo battery. Sending the readings to my MQTT server running on raspberry PI and there is a binding to OpenHab2 to display the results.
Does anyone have a better circuit for monitoring the lipo battery level? All my searches seem to all point back to this type of circuit...some using different resistors.
Would like to get an accurate representation of the battery level displayed on my OpenHab2 dashboard!
Thanks
