I live in an apartment with old crap wiring and have dogs. I'm worried that there could be a fire someday. I don't have the money for ADT so I am going to try to design a fire detector that will email my phone through my WiFi at home. While doing the research I found that there was one that would text you but it involved having a sim card and paying a cell phone provider monthly. Does anyone have any ideals on how this might be possible? Thanks
