You can adjust the temperature from your phone and also turn on sleep analysis. I was hoping that AI feature would still let you control each side, but no, it locks you to one temperature mode, so you cannot use AI mode for each side. The schedule feature sounded like I could change the temperature for a set time, but it was just a simple turn on and turn off. Hopefully, this can be updated soon! ## Frequently asked questions about Navien Sphere for Sleep ### What is Navien Sphere for Sleep?
