Did you ever get a solution to your issue? I’m curious as to how you set up your remote control to send notifications to change your pages because I am actually trying to do the same thing. I’m very new to RPi and MM so I’m learning as I go.
I have both Pages and Remote Control (RC) installed and now I’m trying to create a button on the RC website that I access from my iPhone so that when pressed will load the desired page. Any push in the right direction would be appreciated.
