EmonTx - Wireless energy-monitoring node

Main EmonTx page: http://openenergymonitor.org/emon/emontx

Builds on JeeLabs software and compatible with JeeNode hardware

Libraries Needed

• RFM12: http://github.com/jcw/jeelib
• Mains Voltage and current: https://github.com/openenergymonitor/EmonLib
• Temperature control library: http://download.milesburton.com/Arduino/MaximTemperature/ (version 372 works with Arduino 1.0) and OneWire library: http://www.pjrc.com/teensy/td_libs_OneWire.html
• ElsterMeterReader: https://github.com/openenergymonitor/ElsterMeterReader

EmonTx Code guide

The EmonTx code guide goes through main components required to put a full emontx firmware together. It's recommended that you work through these examples first so that you have a good understanding of how the full firmware's work.

• 01 - Single CT
• 02 - Second CT
• 03 - AC Voltage
• 04 - Temperature
• 05 - Pulse Counting
• 06 - Elster Meter
• 07 - Transmitting Data
• 08 - Watchdog

Full EmonTx Firmware's

• emonTx_CT123 - Apparent Power Example - Use this example if only using CT sensors. Monitors AC current using one CT sensor and transmit data via wireless using RFM12B to emonBase.

• emonTx_CT123_Voltage - Real Power - Use this example if using an AC-AC adapter with as well as CT sensors. AC-AC plug-in adapter to monitors AC RMS voltage and give real power and current direction readings.

• emonTx_Pulse - Use for counting pulses from pulse output utility meter (flashing LED). Optical sensor can be used to detect pulses.

• emonTx_Temperature - For using multiple DS18B20 temperature sensors on a one-wire bus with emonTx. Uses direct addressing method, run the 'temperature search' sketch to find the addresses of the DS18B20 sensors and insert into main example. http://openenergymonitor.org/emon/buildingblocks/DS18B20-temperature-sensing

Note: CT must be clipped round either the Live or Neutral wire, not both!

When the example has been successfully uploaded the green LED should blink quickly once very 10's
