IOTA Reader was designed to visualize messages generated by IOTA devices, which provide data on usage (power, water, gas, heat) or other measurements: temperature, humidity, pressure, distance etc. The application allows users to connect devices using ID and passcodes provided with the devices and then view collected and processed data on dynamic charts. Users may set alerts individually for each device and get notifications. For users’ convenience the devices can be individually named. Each user may have access to multiple devices and the same device may be accessed by many users, if they have access to correct ID and passcode.
