The NTP server makes sure your device maintains an accurate time, preventing data
errors.
If it is required to whitelist the MAC address of your device for Internet network access,
the MAC address for the Kaiterra Square can be found directly on the device, under the
front cover.
While Internet Network connectivity is recommended, our Kaiterra Air Quality Monitors
can be used in oine seings. For example: Modbus/RTU communication can be
established via RS-485.
If oine communication is used, we recommend regularly connecting online to check for
firmware updates as they ensure device stability and functionality.
