Kraftspa — Support

Updated 7 November 2026

Kraftspa runs your Balboa hot tub from your iPhone. If something is wrong, confusing or missing, write to us: a real person reads it.

Please include the four characters on the controller's label and roughly when the problem happened.

The full manual is in the app, under Settings › Manual.

Privacy

The full policy is at atemkraft.dev/kraftspa/privacy.html. The short version: no account, no analytics and no advertising. Your tub's settings and history stay on the controller. Alerts and remote access pass through Atemkraft's relay encrypted with your phone's own key; the heating Live Activity, if you turn it on, is not.

Safety

The spa pack carries 240 V. Switch the breaker off before opening it, and follow the manual that came with your controller.
