Sorry, I don’t know about Git branches. The emonLibDB library was published here in the forum, and full documentation and example sketches showing the use of the API calls are included in the download zip file. > [@EmonLibDB - Version 1.0.2](https://community.openenergymonitor.org/t/emonlibdb-version-1-0-0/23535): > > EmonLibDB is a Continuous Monitoring library specifically for the EmonTx4 energy monitor. It is able to monitor continuously 3 voltage channels and 12 current/power/energy channels, three pulse inputs (or two pulse inputs and one low voltage analogue input). It has has not been possible to include temperature measurement. Like emonLibCM, emonLibDB will always give an accurate measurement of the average over the reporting period of the voltage, and for each current/power channel the current, r… --- _[View the full topic](https://community.openenergymonitor.org/t/emontxv4-firmware-current-and-pf-calibration-printout-incorrect/24216)._
