Do I need a relay module if

Hello. Do I need a relay module if I'm going to replace my existing DSC 1616 with the conversion kit if I want to be able to arm and disarm my system remotely? Thanks in advance.

Yes, you do. I just bought one to do the same thing. Check out this guide: GitHub - scarpazza/home-assistant-konnected-tutorial: A minimalistic tutorial on Home Assistant - Konnected Alarm board integration
