Most of the Kogan SmarterHome™ products only support 2.4GHz Wi-Fi networks.
This type of connection provides stronger connections over larger areas and through different mediums, walls for example.
This was a design choice to ensure that the smart device could be used through the app even when placed very far away from the network source. As an example scenario, a heater installed in the basement could still connect to a signal generated on the top level of a house.
Most routers support dual-band access and as such would allow connections from devices on each band at the same time.
Overall, the usage of the smart device in the context of a smarter home is optimised by using the 2.4Ghz band.
