If you already are paying a monthly fee for alarm monitoring they should be able to add temperature, water, power failure sensor for reasonable if not free fee. I got rid of my alarm monitoring company with the monthly fees. I installed a system called Sensaphone it has a built in temp, power and microphone sensors. It is easy to self install, dials a variety of phone #'s you program, you can even call in to the unit and get updated that things are normal. It also has several add on equiptment for security. Just type in Sensaphone you can read more. The panel is about $400 but you will save that in 1 year of monitoring. Check it out.
