Replaced everything with the Qolsys IQ panel 4 and Alarm.com (ADC). Also have a secondary panel for our bedroom. Cost $22/month which includes professional monitoring (includes cell service with dual path). Leaving my OP2 in place to handle some things as I continue to migrate. Simplified a lot of my automation as it has built up over the years as there were things really not needed. Using HomeSeer for some local lighting automation (not covered well by ADC) as well as other Lutron RA2 features which I did not use before. Integrated my Garage Door Controls, Thermostat, Irrigation, Locks, Sonos and more directly into ADC. Some cool new features that I didn’t have before include smart arming and bluetooth integration. When you come home, your phone connects to the panel and automatically disarms the system. Smart disarms my system if after 5 am (on stay) and motion is detected (could have done this with OP2, but didn’t think about it lol). Still learning. Certainly the system has some limitations especially the cloud control of devices, but they always can be operated manually and/or with a separate app. Not an issue yet, but this does add a slight delay. OP2 was much more powerful especially with automation, so had to scale back a bit. Trade-offs!
