I want to come up with a low-temperature alert system so I can be notified that there is insufficient heat for whatever reason (e.g. failed boiler, or ... ?).  There are some systems in the several hundreds of dollars price range that could either hook up to my WIFI to a monitoring service (sometimes with monthly fees), or a cell-phone based one that sends a text message.  Then there are inexpensive ones for about $60 that can hook up to a plain old telephone jack and dial a number with an automated voice to alert the receiver of the problem.  But I don't want to buy phone service to this place just for this device.

Where I live year-round I have an underpowered build-your-own HTPC computer that stays on the internet all the time and occasionally I access it remotely.  Perhaps I could install asterisk there.  But then I have no idea.  Ultimately I want to get notified somehow (e.g. email) that this phone dialer sent an alert.  Maybe this is more trouble than its worth :-)

Usually the problem with remote locations is the absence of (low cost)
internet connections.

If you have internet access to the property all year round, then get a
usb temperature monitoring dongle (there are several prices around 15-20
$) and find/write a script to query it every X amount of minutes and
send you a notification either by email or even sms using a (usually
free) email to sms gateway

Again if you have internet access you can put the monitor device that
has PSTN output to an ATA and have the ata register to an asterisk at
your home,so you won't need to pay monthly fees to a Voip provider.
That would require to setup a "permanent" asterisk server at your "main"
house, but you could do it with VM image and avoid setting up a new PC
You then need to do some port forwarding in your router for ports 5060
(for the sip signaling)  and 10000-11000 for the RTP stream
Assuming you don't have static ip's in either place you will also need
to set up DynDNS so that the phone knows where to find asterisk

There are several other options but which one is best  depends on
budget, knowledge for hooking up the stuff and time it takes to do it :)
