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.
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.
