OpenEnergyMonitor emonPi Solar PV is an open-hardware Raspberry Pi and Arduino based web-connected energy and environment monitoring unit.
The emonPi is an all-in-one Raspberry Pi based energy monitoring unit making for a simple installation where Ethernet or WiFi is available at the meter location. The emonPi can monitor two single-phase AC circuits using clip-on CT sensors, and can also monitor temperature, and interface directly with utility meters via an optical pulse sensor (optional).
The emonPi is based on a RaspberryPi + emonPi Shield PCB. The emonPi features a ATmega328p 8-bit microcontroller which is Arduino compatible.
The OpenEnergyMonitor system can be used as a simple home energy monitoring system for understanding energy consumption. View and explore real-time power and daily energy consumption in kWh. MyElectric is a web app which runs on Emoncms. MyElectric is also available as a native Android app
The main view shows a moving window power view of site-consumption in the top half and historic daily energy consumption in kWh in the bottom half.
The OpenEnergyMonitor Solar PV monitor is a tool to help you make the most of your solar generation. Providing real-time and historic information on your solar generation and demand matching, it will help you make better use of available solar power. MySolar PV is a dashboard app which runs on Emoncms.
The main view shows a moving window power view of solar generation Vs site-consumption which, can be used to explore matching at any given moment of the day. Site-consumption is shown in blue and solar generation in yellow. The totals at the bottom of the page relate to the current window selected and show at a glance how much of site-consumption was supplied directly from solar and how much of the solar generation was exported to the grid.
Clicking on view history brings up a bar graph showing solar generation and site-consumption on a daily basis. Including how much of the solar generation is used directly on site and how much is exported.
Emoncms is a powerful open-source web-app for processing, logging and visualising energy, temperature and other environmental data.
Extend your emonPi's functionality with some of the following softwares and tools - Emoncms, MQTT, NodeRED and OpenHAB.
The OpenEnergyMonitor system has the capability to monitor electrical energy use / generation, temperature and humidity. The full system is made up of five main units that can be assembled and configured to work for a variety of applications. The system is fully open-source, both hardware and software. All hardware is based on the Arduino and Raspberry Pi platforms. The emonTx, Optical Utility Meter LED Pulse Sensor are a standalone options, while emonTH is a wireless room temperature and humidity sensor node. The emonBase represents an alternative to emonPi. All units are available separately.
