112 Sometimes devices stop working for one or another reason and you need to know what's going on. Also, many devices (e.g. Arduino) memory is small enough to discourage an attempt to log errors on the device itself. For that reason AllThingsTalk allows you to know if system successfully receives or encounters a problem with incoming data.
