Technology Connections has an interesting video about pre-cooling: [VIDEO] The author also made a good point that despite wind and solar being intermittent, they are actually fairly predictable a or less day in advance (thanks to weather forecasts).

That really isn't the same product, as I understand this is an HRV combined with heat pump system where they are software integrated to PID controls that optimize the level of fresh air and weather aware energy utilization, with a system like this and a startup I'm sure optimizations like this [VIDEO] should be possible - this is like Dropbox, can't expect people to roll their own - and you need a fully integrated system to really make this work well without comfort, even simpler if cooling/heating is more efficient via bringing in fresh air this system could choose to do that vs running the heat pump at all!

Technology Connections does a similar thing, over-cooling his house at night as a thermal battery. Video: [VIDEO] Reddit discussion: [LINK] He estimates it at 16 KWh of storage. Same ballpark as a Powerwall, right?
