Just got my Enphase solar system installed today, and now exploring my options for connecting into my Hubitat setup to determine what information I can gather and report on and/or build automations against.
I am using this Enphase Solar monitoring for local reading, but I have a first generation Envoy-R-EU gateway. Not sure if it works on the latest from Enphase. This will give actual production KW (15 min interval), todays KWh, last 7 days KWh, month to date KWh and lifetime KWh.
I wrote my own driver that works with enphase envoy. The token is too long to save as a hub variable so the driver has a method that allows me to re-load it after a hub re-boot. Not a fan of token based api access that needs to be periodically renewed at enphase for my own installation btw.
