Which Raspberry Pi for simple emoncms system?

Getting Started

Hi,

I’ve just come across OpenEnergyMonitor and believe that it will easily meet my needs for monitoring our new solar PV installation.
I plan to put together an emoncms system on a Raspberry Pi using a Lechacal board with 2 CTs - we have a ‘Type 1’ solar PV set-up.
I have been looking for information on choice of Raspberry model for emoncms, but can’t seem to find any - I would appreciate some guidance.

Thanks,
Martin

emonCMS (the downloadable SD Card image) will run on almost anything - I’m running a not-quite ‘latest’ image on a Model 2B.

There an ongoing discussion about using a Pi Zero in another Topic. Does this even work on a Raspberry Zero !? - #39 by borpin

I’m not a Pi expert so someone else who is might well chip in.

As Robert says - it should work on any Pi (there are a few issues currently), but actually, it will run on any Debian based system. Ubuntu is a favourite (though 20.04 not 22). There can be a few oddities when moving away from RPiOS, but I run it on a Virtual machine under ubuntu quite happily.

For the choice of Pi, I still think a 3B+ is the best bang for buck (when the come available again). You can use an OrgangePi as an alternative, for instance.

Thanks both, I have both a 2B and a 3B+ ‘spare’ at the moment so can see which suits me better.
