Greetings,

First you need to have water, temperature, and heat sensors. We are going to
assume you have all of those and that your only question is about
communications.

purchase a prepaid mobile telephone with the ability to speed-dial a number
by holding down a number key
program in your phone number as the speed dial number
remove the battery and plug the telephone into the AC adapter.
plug the AC adapter into a alarm system or computer controlled relay
power the computer and replay with a UPS (uninterruptible power supply)
caller-id tell you there is a problem with the house
Some might consider this setup as "rigged" but the price is right!

If your computer is the device controlling the relay you can set the phone
in front of the computer and play a looped sound out of the computer speaker
to tell you what the problem is. It might call you once a week to yell
weekly-test at you for 45 seconds until it turns the phone relay back off.

Hope this helps,
William

I have a remote home on the lake that is 10 about miles from my house.
I was wondering if there was a system that could radio my house
if the lake house is in trouble; no electricity, no heat, or flooding...

I would prefer to avoid a monthly bill associated with an alarm system.

any ideas?
