IoTaWatt is an open-source, open hardware project to produce an accurate, inexpensive and easy to use energy monitor.
extraAC is a fork to add DB18B20 temperature sensing to the Iotawatt platform.
Temperature sensor support (DS18B20) is on ports 13 and 14. Two temperature sensors are supported per port.
##Convert your IotaWatt into an extraAC
Make the following hardware changes to the IotaWatt circuit board: Connect ports 13,14 to the NodeMCU D3 and D4 instead of the ADC (cutting a few traces and adding a few wires).
Circuit board modifications to change ports 13,14 to temperature ports
Build this repository using PlatformIO and upload to your IotaWatt to add the extraAC temperature probe functionality
