Open Energy Monitor

Exploring the context of renewable energy and zero carbon energy use.

Open energy monitor.

Open source monitoring for understanding energy. If monitoring a split phase system the power values from each leg can be summed in emoncms to calculate the total power. The openenergymonitor system has the capability to monitor electrical energy use generation temperature and humidity. See setup logging locally.

These can be configured to work for a variety of applications. The emonpi by default reports power1 plus power2 this input will need to be logged to a feed. The system is fully open source both hardware and software. The openenergymonitor system has the capability to monitor electrical energy use generation temperature and humidity.

Open source hardware tools for energy monitoring and visualisation. Burden resistor sizing for openenergymonitor energy monitoring hardware. The system is fully open source both hardware and software. The standard emontx v3 uses 22ω burden resistors for ct 1 2 and 3 and a 120ω resistor for ct4 the high sensitivity channel.

All hardware is based on the arduino and raspberry pi. The emontx v3 uses a 3 3v regulator so it s v cc and therefore aref will always be 3 3v regardless of battery voltage. All hardware is based on the arduino and raspberry pi. The system is made up of five main units.

Emonpi home energy monitor version. Monitor electricity temperature and humidity. The emonpi is a web connected open hardware raspberry pi and arduino based electricity and environment monitoring unit.
