we finally figured out most of the critical bugs on the v2 controller boards, things are never as easy as it seems - i guess building your own custom linux computers from scratch was not going to be as easy as i thought it would be. this one really tiny smt resistor that was picked and placed in the wrong orientation took almost 2 months to catch since i thought it was a kernel or software issue, but we are good to go now. here are some v2 visualizations of my office garden ... ... does your flood and drain garden behave the same as mine http://db.kijanigrows.com:8080/grafana/#/dashboard/db/kj_v2_01

the visualizations are done using influxdb and grafana as per this tutorial in in my website
