Love my new Rachio. Having fun playing with it. Had it all programmed and set up in 30 minutes.
I suggest a right-angle male plug be used on the power adapter cord instead of the straight one that is on there now.
I installed my Rachio in a protective ABS enclosure (lots of lint and dust in the laundry room). I had to install the Rachio off center in the box to the left, to accommodate the power wire sticking out on the right side. Anyone wanting to install a Rachio outdoors would need to place it inside a weatherproof enclosure. Many of these enclosures are smaller that the box I used and would be a tight fit with the straight plug protruding on the right.
Other side benefits might be that power cord would drape downward a little smoother, and a right-angle plug may be harder to pull out by accident compared with a straight one.
