Emoncms 9

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.

Branches

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. See change log

• ARCHIVE low-write (v8.5) - Old emonpi/emonbase emoncms version (July 15 emonSD 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
