I somewhat recently connected Emporia Vue's 'net production/consumption' metric to my OpenEVSE so I can make use of the 'eco divert' feature that only charges from excess solar production. Since my utility charges for transmission of net-metered power, this leads to some savings. When we have cooler summer weather it shows up very nicely on the graph.

(Hopefully this is OK for this community. Not news, but could be a nice highlight/discussion. If not, glad to find another spot to share it.)
Satan approves.
