I built my house 4 years ago and I bought 4 Grafik Eye 3106 for my living room, family home, bedroom and dinning room. I recently installed a Honeywell Vista 20 with Tuxedo panel. I read the product brouche, it is able to connect 2 systems using RR2 or RS232. I'd like to get some advices if I can connect them via RF, RS232 or WIFI without upgrading the Grafik Eye 3106 to QS version. I also accept to install gateways between 2 systems.
