I am interested in discouraging A/C usage unless Solar is on. That doesn't mean we don't allow A/C, but that we auto-turn Ecobee AC on when solar power is generating, and we auto-turn it off when solar power is not generating. A person can go turn it back on if it's necessary. I would've thought that IFTT could be used for this but I don't see any Tesla Solar integration. There is Home Assistant - a possibility, though I do have a Homebridge setup that I'm not using right now. That seems like an overkill…but hey if that's the best way, I'll consider it.
