Googlies,
@MapHouse in Low Temperature Notifications/Alerts asks my question for different reasons:
As a Google Nest Thermostat owner, I want Google Home to alert me intelligently (easy for Google!) when the temperature in my home is either meaninfully high or low. Things go wrong with heating and with cooling systems so they aren't heating or cooling and an obvious observable symptom is the temperature falls or rises meaningfully below or above the target temperature. An alert on this symptom helps us owners respond to the problem.
In my case and for understandable reasons, this is more likely to happen in winter overnight when the schedule lets the house cool and the heating system cannot warm up the house just before we wake. And it takes longer to recover.
I don't think this is too much to ask! It's obvious, there's demand for it, and other competing products have this feature.
It's a win-win and lowers energy usage and typically carbon usage because catching this early requires less total energy to recover from. Google could literally save lives in the homes of the elderly.
I get that there are complexities: aberrant weather can let a home get colder or warmer than is otherwise seen. And the Schedules feature means some of these deltas are a feature, not a problem. The answer to a programmable behavior is more programming: the alert feature has to track when a temperature difference is the difference between the current schedule that just started and the previous schedule that just ended.
I don't see that Google can't add this feature to Google Home (so perhaps I'm posting in the wrong product?). Absent evidence to the contrary, I have to conclude that Google won't.
