I don't really have tons of scenarios in mind at the moment. The only one I would like to exploit to date, if it can withstand it, is using modules to monitor my freezer, and refrigirator in case the temperature go above some point in case of a power outage, and notify me on my cell if it happen. Is there some IFTTT recipies already available (for this, and in general)? I haven't seen any in the IFTTT database
