All this tech talk sounds like it answers my question, but it's all Greek to me. Fortunately my future son-in-law is a techno geek and can help me with this type of project.
My concern is leaving the dogs in the trailer while I'm gone during the day this summer and if the power / AC fails it would be like leaving them in a hot car.
Other than fixing a camera on a large wall thermometer, is there a way to monitor the temperature and receive an alert at a set point? Am I watching too many TV commercials for monitored alarm systems... Has anyone had a vendor install a monitored alarm in their RV at a fixed site?
ADDED LINK: THIS IS IT... I don't need to see the dogs, just make sure they don't have heat stroke!!!
