I have an Enphase solar system with battery and have three Lennox HVAC systems with S40 thermostats. Should I expect any issues using Home Assistant to adjust the S40 thermostats based on power data from the Enphase IQ Gateway? My intention is to coordinate the HVAC load with the solar and battery capacity to minimize the peak rate utility usage.
I looks like both of those can be integrated…
… so it should just be a question of installing and configuring the integrations properly, then setting up the automation to do what you want.
