The device is optimised to be used with WiFi to allow regular synchronisation with the IoT platform and to enable alerts. However, if you want to operate the device in an area without WiFi, it will work perfectly well. Each device can store over 300,000 records in its internal memory. If you do install a device in an area without WiFi you will have to manually output the data using a computer or by periodically moving the device back in range of a WiFi network. In this situation you won’t benefit from the automatic alert functions.
If you want to use this approach we suggest setting up your device with a working WiFi connection first, then move it to the measurement environment. Alternatively you might be able to share your smartphone’s mobile Internet to setup the device.
