We have an integrated pool and spa and have a daily schedule of turning on the pump and heating for each side. This has worked flawlessly for most of the time we've owned the house (< year). Sometime in the last few months, the heater stopped initiating from the app. The app and easytouch panel will show the heater on per the schedule and water temp / temp setting, but the heater itself doesn't initiate. When manually started by pushing the spa button on the unit, it works fine. Interestingly, the app will turn the heater off. I've read every thread I can find, but haven't found one that seems to address this issue. Help appreciated!
