If I’m understanding the little bit of info I’ve been able to find on the internet. If this is correct. The main boards are the same and the differences are the control keypads. I have a P4 control keypad PN: G1-0660090-1. My main board is PN: G1-011049F-1F software rev 4.45. I would like to do an upgrade so I can install the Aqua Connect Serial Home Automation Interface Module (AQ-CO-SERIAL) to have 2 way communication with my Homeseer Home Automation system. Do I just need to replace the P4 with a PS4 keypad control to make this work? Any help or advice from any pros out there will be greatly appreciated. Thanks ?
