It really is not overkill at all, but can understand why PBs want to use their tried and true workhorse, the ET. The Intellicenter is the newest automation, but some PBs do not have a lot of experience with them, and they know how to install, setup, and maintain an ET system so there is no need even exploring a newer option. Yes, the Intellicenter is more of a robust system, but overkill it is not. That all being said, you probably will not be disappointed in the performance of the ET system with screen logic. There are supply chain delays in even getting Intellicenter systems, so that, with your PBs preference of the ET seems like a solid plan.the Intellicenter seems a little overkill
I connect to my Intellicenter locally through my Pentair app 99.9% of the time, and really wouldn't even notice if the Intellicenter servers were down. At home, I never would need to connect to my IC through the online servers.when Pentair's servers go down (as the do often) you can not control your IC systems internally or externally via app, PC etc. With an ET system with SL you still can.
Once in a while, I may check my app while I'm not at home for temps, or whatever, but never noticed having an issue connecting, maybe I am just lucky that when I try and connect from outside my home, the servers were up.
