Hi!
Just thought I would share my installation pictures.
I installed my OS in the Orbit enclosure, Model # 57095, just like several previous users, but I routed the cables a bit different. I used a hole-saw an added a new hole in order for me to better mount the OpenSprinkler and the OS Zone Expander. For the power, I just re-used the old 24V AC Transformer from my previous RainBird system put in by my builder.
I also used the TP-Link TL-WA850RE N300 Universal Wireless Range Extender to connect the OS to my existing network via WiFi.
