EmonPI with 3/4 CT Inputs

Submitted by techupin on Fri, 02/10/2015 - 17:29

Hello,

Are EmonPI with 3 CT Inputs in Design Pipeline, any chance of Buying them at the Online Shop in Future? Will be really good for measuring (Apparent) Power of Three Phase systems!

Regards,

I understand a genuine 3-phase monitor is under consideration. I have no idea what form it will take.

The emonPi was constrained to 2 current inputs by the size of the enclosure and the desire to retain the 3.5 mm jacks, so a 3-phase emonPi with 3 voltage and 3 current inputs looks a little unlikely.

Meanwhile, you might want to look at this thread: http://openenergymonitor.org/emon/node/11324

Thanks for the comment and link.

I would also like to ask if EmonPI is completely opensource, and if one can download and modify the Schematic and Board Layouts?

I am asking because, I saw:

https://github.com/openenergymonitor/Hardware/tree/master/emonPi

but then no BOM and Firmware Programming/Download info... is this encouraged?

Thanks!

As far as I know, everything here is Open Source. I managed to find the BOMs, Gerber files, Eagle layouts and schematics, several versions, so I think you didn't look in the right place. There's more info on the Wiki, or didn't you look there?

Thanks, indeed it is. Looked at the directory v1.6 and not v1.5. BOM details are available in the dir v1.5.
