I’m guessing that we have the same enclosure based on your description, and I do have mine plugged into the outlet on the left INSIDE the enclosure, so I wonder if you’re right about different sized power supplies? @emil, do you know if there have been different sized adapters that ship with the IRO?
What you mentioned above is about all I’ve noticed. A fairly standard/versatile configuration for conduit connections that I’ve seen is four holes on the bottom of the enclosure spaced 3" apart. I think that would work for most standard installations. Any enclosure you guys look at obviously needs to fit the Iro, including the power connector sticking out on the right side, and needs to have the 110v outlet in there as well, with room for the adapter. I did some pretty extensive searching, and couldn’t find anything online or in stores that met all of those requirements… the Orbit was just the closest for me.
