I had connection issues initially. Here are my suggestions to bump the app up: 1. Remind users to hold the reset button on the side of the spec controller for 15 seconds if the controller is not flashing the little o 2. The default ports 1 and 2 cannot be edited or removed. My pump is port 3 for some reason so those default ports are in the way. 3. Why does the app not show swimmer usage history 4. I imagine most users only have one system. I would expand the app to show error codes , health and status, maintenance needs, etc to make the app more useful to the homeowner.
