Emoncms is an open-source web application for processing, logging and visualising energy, temperature and other environmental data and is part of the OpenEnergyMonitor project.
Version 9 of emoncms has been developed by Chaveiro with a significant list of improvements, see forum thread with full change log
Note: We are currently reorganising the emoncms branches. The master branch is now the same as 9.x.
-
master - The latest and greatest developments. Potential bugs, use at your own risk! EmonCMS 9.x forum thread
-
stable - emonPi/emonBase release branch, regularly merged from master. Slightly more tried and tested.
-
low-write (v8.5) - The old emonpi/emonbase emoncms version (July 15 ready-to-go SD card image). Low-write mode is now available in v9.0. The low write version of emoncms is designed for running on SD cards. This is a cut down version of emoncms supports only the phpfina and phptimeseries feed engines (no in built feed averaging or histograms) and a reduced input processor set. Archived branch
