If more than two emonTx's are required on the same network then further nodeID values can be set via RF node ID serial config. The nodeID can be selected at time of purchase or set using the on-board DIP switch to toggle. Multiple emonTx unit's can operate on a single RF network posting to a single emonPi / emonBase web-connected base station (Raspberry Pi + RFM69Pi), each emonTx on the same network must have an unique node ID.
When using the pulse counting method to monitor power from a utility meter the sample rate is limited to the number of pulses at low power values the interval between pulses can be extremely long. Note: CT sensors give a much better reading of instantaneous power than pulse counting, we recommend using a CT wherever possible.
External Encapsulated Temperature Sensor. USB to UART programming cable (for uploading customised / updated Arduino firmware sketches from Arduino IDE). Aluminium enclosure & custom fascia - assembled. Firmware is available which will allow for 'approximate' 3-phase monitoring (described here), which we can upload prior to shipping if it is requested. The emonTx with the default firmware is suitable for use on a single-phase supply, or on a split-phase supply, or on one phase of a multi-phase supply. The discrete sampling firmware is less accurate than the continuous sampling firmware so its worth only selecting this option if you need to power the EmonTx from battery power. In order to preserve battery life the EmonTx needs to go to sleep between readings, we upload our discrete sampling firmware to the EmonTx to achieve this rather than the standard continuous sampling firmware. Select the 3x AA battery holder option above if you wish to use this option. Optional: The EmonTx can be optionally powered by 3x AA batteries. The unit is manufactured and assembled with care in the UK. #Pv beancounter free
Made in UK with RoHS components free of conflict materials. Aluminium wall mount enclosure with recycled acrylic fascia. Arduino compatible ATmega328 8-bit microprocessor. DIP switch selection of RF node ID and 240V/110V AC adapter calibration selection. RFM69CW 433Mhz Low Power RF Module with SMA antenna. Single AC-AC adapter can power the unit and provide AC voltage measurement. 
Terminal block access to power rails, digital and analogue I/O, IRQ port and PWM for connecting pulse counting sensor / 3x DS18B20 temperature / Aux sensors. 1 x RJ45 I/O - connect chain of 3x DS18B20 temperature sensors or pulse counting IRQ sensor. 
1 x high sensitivity single-phase CT current sensor input channel (18.8A / 4.5KW 240V max). 3 x single-phase CT current sensor inputs (100A / 24KW 240V max). 
Measure AC Apparent Power, AC Real power* and AC VRMS voltage (when AC-AC voltage adapter is connected).(Alternatively 3 x AA batteries / 5V DC USB Mini-B Power Supply can be used for less accurate Apparent Power measurements.) 9V AC-AC adapter power supply (UK Plug), (Euro Plug) or (US Plug) - enables accurate Real Power measurements.To get started visit the OpenEnergyMonitor Setup Guide. Alternatively it is possible to add Wi-Fi directly to the EmonTx with a ESP8266 WIFI adapter. The emonTx is designed to be used in conjunction with an emonPi or emonBase web-connected base-station to post data online to and/or log data locally to the Raspberry Pi's SD card.

The emonTx V3.4 is a low power wireless energy monitoring node designed for monitoring AC electrical power on (up to) 4 separate (household/building) circuits using non-invasive clip-on CT current sensors and an AC-AC Voltage adapter to provide a voltage signal for full Real Power calculations and AC VRMS readings.
