You should manufacture an out door enclosure with the reverse wiring configuration. Not everyone has legacy controllers with wiring on left and zone wires on right. Mine is exact opposite and will have to return my Rachio 3.
It really wouldn’t take a lot of work to swap things around…not sure what the piping looks like further down, but you could use some PVC flex conduit about half way down for the power supply side. If you can handle the 110v power crossover to the new Rachio enclosure, you should be able to handle that as well.
