233,
Make sure the system is in AUTO and then go look at the pump's display. It should say "Display Not Active". If it says RPM or something like that, then your pump is not being controlled by the EasyTouch. Most likely you have lost your RS-485 com port.
If the pump's display is blank, then it is not getting any AC power.
Use your app to turn on a pool light, the light icon in ScreenLogic should turn green. Then go outside and ensure the light is actually on. If on, turn it off using the button on the EasyTouch's main panel. This should turn the light icon in ScreenLogic off.
Let me know the results of your tests, and we can move on from there.
Thanks,
Jim R.
