We have a second home that, from time to time, suffers a heating problem.
We'd like to install something that would monitor the air temperature, and if
it fell below a certain level, would call a pre-programmed number.
I've seen devices you call into, but that will not work as the phone there has
voice mail on it.
As an alternative, are there any devices that can monitor a home and can
provide continuous reporting via the internet?
