I have a 5 person Watson/lifesmart tub with balboa guts (110v). The hot tub is on the deck of our ski house in NH. We generally turn down the tub and the turn it back up when we get up for a weekend. It would be super awesome to be able to control the HT remotely via app. After a long search and conversations with spaguts and other parts stores it appears the only option to do this is to update the spa pack with all new components, heater controller, etc. Has anyone else done this? Is there an easier way?
