Hello!

You need some other connections too, you can find the schematic here: http://solderpad.com/openenergymon/emontx/

You need the Pins 16-19 and pin 4 on the processor, the connection on the RFM12B can be found in the datasheet. You normally need the 2 upper pins left and all pins on the right except the middle one.

Hi, I've done exactly the same myself.  Thankfully, both components have since been successfully salvaged.

The RFM chip worked OK without any repairs, as shown here.

For the board, I bypassed the damaged tracks using fine 'Kynar' wire, as shown here.  All the necessary information is on  Solderpad.

Phew, I have done that same thing on couple occasions. You are not alone. The beauty of the PCB is gone, but you can still make it work as noted above ;)

Thanks, for the tips and the photo, I will try today, and see how it turns out.

I am glad others have done it !

if it fails the I shall await the new v3 :)

Just to let you know that i have build the 3 phase model and i have extend it with an extra power measure on phase 1 using the emontx shield and a arduino uno.

By adding a fourth power measure i had to re-adjust the delays for the other phases a bit.

Right now i am measuring 3 phases and the solar inverter and everything is working very good.

Of course it took me some time to understand the whole system and how the software works etc. but now i can say that i understand it very well. It helps that i am an electronic engineer with a lot of computer experience.

Also it took me quite a lot of time to get it working on the internet but as i said, it works very good now.

I am now busy familiarizing myself further with C++ because i was used to pascal and basics .

Thank you for the very interesting articles

Well its working after a bit of wiring :-)

Oddly the temp is about 10 degrees out coming in on the input as 3047 when scaled by 0.01 is 30 Degrees.

Another temp from glcd reports 20.2 in the same room?

silly me, that was battery level !

all working
