The dobona application allows its user to remotely connect to any of three hardware boards. doboR, doboRI and doboT are small-size low cost boards that are used to switch on and off up to two external devices or read a temperature depending on the type used. Each board contains a Wi-Fi module that allows it to connect via an external router to the internet. The user can hence either remotely activate/deactivate any of the two external devices via a smartphone or tablet over the internet (doboR and doboRI), or read the temperature from a sensor wired to the board (doboT). Typical use of the dobona app is for home/office automation to remotely switch a heater, boiler, air conditioner etc... or to read the temperature of a Freezer/Refrigerator and receive email notifications in case of relay switching or abnormal temperature reading. The user can control several boards from the same app and several users can control the same board from several phones/tablets.
