I don't think there is any issue since the automation is only doing what I can already do manually with the Tesla app, or by manually turning off/on devices driving power usage in my home. Darwins app simply lets me schedule and/or trigger changes to occur (again that we already can do in the tesla app), based on variety of other conditions occuring in the home, that I might otherwise make manually if I had the time to monitor the home usage and PW SOC all the time.
Also, SRP is getting what they want via their rate plan. I.e. in order for Solar/Renewables to not negatively impact them (duck curve and all), they need to drive me to only use power during their own defined off-peak rate plan hours. They encourage this with very cheap rates. So I maximize my usage during this time, and if I have extra solar during this time, then I also lower what I use during off-peak.
Next, SRP makes peak hours rates and demand charges very high during their defined peak rate plan hours, this is to encourage me to minimize my usage during peak hours where they otherwise risk having trouble meeting overall area peak usage for all homes in the valley of the SUN (otherwise the demand charges pile up pretty quickly on my bill). So my automation actually helps me zero out all peak rate hourly usage. So when the SRP grid is under maximum pressure to keep up, I'm using zero power.
All I'm doing is maximizing to the most extreme ability I have, what they already are trying to encourage with the solar generation rate plan - which to be honest is already skewed to their benefit quite a bit. Also, they have multiple meters; on the whole house, on the battery, and on the solar. They know exactly how much power is coming in-and-out of all these sources (out only from solar clearly). So they know exactly how I'm using the system, and I'm actually using it exactly they way the want me to use it, which the automation helps optimize.
If anything raises eyebrows, it might be how I manage to zero out peak usage (the way they desire), but do it with less solar (4.1kw) than many people here in Phoenix on 4400sq/ft of air condition space (includes my separate workshop). The extra PWs and extensive automation is what allows that to occur. I think this is exactly the type of information they are looking to capture.
