OpenEnergyMonitor

Open source monitoring for electricity, solar, storage and heat pumps.

A versatile and expandable system of sensors and integrations built on the Raspberry Pi and Arduino platforms.


Introducing the emonPi3

A 6 channel electricity monitor with an integrated Raspberry Pi. Supports single or three-phase monitoring, wired temperature sensing & pulse counting. Can be used as a base-station for further sensor nodes. Full local or remote data logging and visualisation capability via EmonCMS.


Expand your system with:

emonTx6: A 6 channel electricity monitoring node. Great for expanding an emonPi3 monitoring setup where more CT inputs are required either in the same location or in a different part of the building. Transmits data via 433.92MHz radio.


emonTH2: A battery powered, wireless, room based temperature & humidity monitoring node. Transmits data via 433.92MHz radio to an emonPi3.


Heat Pump: See pre-provisioned level 3 heat pump monitor bundle and the heatpumpmonitor.org initiative.


Data logging and visualisation with EmonCMS:

Local on the emonPi3. Remote on EmonCMS.org

Pre built dashboards, advanced graphing tools, flexible input processing.
