If you want to know, remotely, if your house is burning down, you can spend $450 a year for a monitoring service and who knows how much for a system that dials them in case of alerts, or you can buy Nest.

I see this as priced against monitoring services and systems that phone them.

Compared to those, this is cheap.

The problem is Nest doesn't connect to a central monitoring center (as far as I can tell) and many insurance companies require central monitoring. I would love to have these, but I won't buy them if the insurance company won't sign off on them.

Well, if your house is burning down, and you're not in it, there's not anything you can do anyway, and you finding out before you get home doesn't change anything, so that's not that useful.

Not true, you can call the fire department.
