The tado° devices communicate via radio at 868 MHz using the IPv6 enabled “6LoWPAN” protocol. The advantage of using this protocol for the tado° wireless network, instead of Wi-Fi (2.4 and 5 GHz), is the extremely low power consumption combined with superior range inside buildings and through walls. Our tests in conventional residential housing readily achieved coverage of 2- and 3-storey dwellings. The actual range is naturally dependent on the construction of the particular building in question and may differ from the test results.
