Installed the Learning Thermostat around mid September and the graphs show the electric use for cooling (almost to the point we'll need heating), during the first 30 days.
I was hoping to get some suggestions from Google/Nest support on how to make the Learning Thermostat aware of the periods solar system generated peak power. Even a simply setting (static) which would work a high percentage of the time especially during April through September. Las Cruces, NM gets about 294 days a year of sunshine and the cloudy days usually occur in November through March.
The thermostat seems to adjust the temperature in anticipation of peak demands. I didn't get any specifics from Google. My electric bill has gone from zero to a credit of about $20 a month. I'm in Las Cruces NM, but get electric from El Paso Power. Texas is trying to really limit net metering, so far the PUC in New Mexico has been holding firm. FYI I have 24 Toshiba panels and Enphase micro-inverters and control system. A sunny month it produces about 1.6 megawatt/hours.
