My onpesprinkler is live from yesterday !
I am now trying to have the hardware clock working.
The TP-Link issue is still open, had very few return from their support.
I’ve tried to run OverlayFS on it but have somme issues when rebooting: http://blog.pi3g.com/2014/04/make-raspbian-system-read-only/
For the integration, as I understand, if I have my own formula, I would need to have it “custom” watering per sprinkler and I guess posting through the API the watering adjustment is the right way for that ?
