With the amount of work to run the conduit and given the cutout is likely not the same in the gateway 2 it is simply not worth it for the little gain there is if you ask me and I'm one who was promised a free upgrade. In my case the gateway is on the outside of the house and they had to stucco around the conduit, but looking at the current specs the sensing is not worth the hassle especially if the max is 100A vs the current rated for 200A
