What all should I buy for an home electricity monitor?

Hi,

I visited the OpenEnergyMonitor.org shop, http://shop.openenergymonitor.com/home-energy-monitor/, to purchase an electricity monitor for my house. My specifications are

A. To monitor power as accurate as possible and collect data as CSV file (or similar) on computer

B. For my house is in the UK

C. Not to measure voltage because I do not have AC power unit near my meter

D. Not to display, using equipment such as emonGLCD, because I need to download the data directly on to my computer

E. That I don't need to purchase a micro-USB cable because I have one with me

 

If I purchase the following, will I have the full kit?

1. 100A max clip-on current sensor CT: £9.60

2. emonTx V3 - Electricity Monitoring Transmitter Unit - Fully Assembled: £60.00

3. Raspberry Pi (Model B) - Web-connected Base Station: £32.40

4. RFM12Pi - Raspberry Pi Base Station Receiver Board: £21.49

 

Am I missing any connectors, memory etc?

Regards,

Sumesh

I think you have it pretty much covered there except for power supply/cable and a  network cable/dongle for the Pi.

You may also want to consider a programmer, although you shouldn't need one to get up and running you may want/need to update or change the emonTX v3 firmware at some point.

Oh and a SD card for the Pi...

Hi,

 

Many thanks for your response. If I get a dongle for raspberry pi will I still need RFM12Pi?

What do you want the dongle for - WiFi? If so, yes, you still need the RFM12Pi. (The radio frequencies and protocols are vastly different. The RFM12Pi talks to the emonTx, the dongle talks to your wireless router and your LAN.)

Ah! Many thanks. That clears it all.

Cheers,
