The Caldera Spas app is powered by the Connected Spa Kit, which is a dealer-installed option available on most Caldera spa models built after 2014. Spa must be within 150 ft (45m) to Home Network Router to work. Ask your dealer for details.

The Connected Spa Kit is a remote system that relies on connections of Wi-Fi components between the spa and a home network. The system is for the convenience of the hot tub owner and does not replace regular physical inspection and/or maintenance of the hot tub. Not recommended for tablets.
