We have solar panels tied to the grid (no battery), and because it's usually sunny where we are at, I have the A/C running during peak solar production times during the day. (Because the rate Rocky Mountain Power gives us for electricity sent to the grid is less than half the rate we pay for electricity, it's cheaper to pre-cool our home during peak solar production when it's sunny, even if we're not home at the time.)
I'm interested in a way to trigger our thermostat to a higher temp (i.e. turn off the A/C during the day) when either 1) our solar production falls below a certain threshold or 2) it's overcast. Our inverter is a Sunnyboy, and as far as I know, does not integrate with any tools to make this happen. Are there any products I could use to make this happen? Alternatively, I've done a quick search and some HomeKit products such as the Philips Hue Dusk-to-Dawn Outdoor Motion Sensor has a light sensor, but could it measure whether it's sunny or overcast?
Has anyone successfully tied their thermostat behavior to solar production?
