Unreasonably pleased when I can charge from excess solar

cross-posted from: https://piefed.social/c/energy@slrpnk.net/p/2233823/unreasonably-pleased-when-i-can-charge-from-excess-solar

Additional detail for DIYers: I used vuegraf to publish MQTT from my Emporia Vue, which OpenEVSE can natively consume.

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.

EVSE view:

(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.)
