I have Texecom Elite with both Smartcom and ComIP. My understanding is you need both to enable integration with Control4 and use the Texecom App. If you don’t intend on using the Texecom app then my understanding is you don’t need both modules.
Installation has been done for a few years now and it seems to work well. I have a couple of niggles and looking for a new alarm installer as not many understand the integration with Control4.
With regards to integration, this has been a game changer. I now have the ability to use individual room sensors and door contacts for various programming. I particularly like the ability to turn lights on with alarm sensors. The ability to have notifications and status along with automatic setting of the alarm has been great. For example, I have an evening routine which automatically sets the alarm at night. There are a few niggles, for example the Part Arm settings are not named so unless your a frequent user or only have one part arm, it can be confusing. I find myself using the Texecom app if I need to set and unset the alarm but this is not frequent at all.
For the small cost difference, I would recommend both the Smartcom and ComIP.
