Once again, GOOGLE is your friend.....

Try a Google search for: "cell phone based remote temperature monitor"

There are several systems available. Some are as simple as a device that calls your cell phone if the set temperature is warmer/cooler than the setting, others that are internet based and some even have a commercial monitoring service, similar to security systems monitoring.

So, depending on how sophisticated you want to go, there are a number of choices available. Maybe you'll find the one that fits your needs ????
