Thank you @Thomas_Lerman and @tmcgahey !
The Rainbird is installed inside the garage.
I’m not sure what is that angled pipe thing that is connected to the bottom
That pipe seems to be connected to the transformer unit which has the two power cables coming out of it and connected to the two 24 VAC.
IIUC, to replace with Rachio3, I still need a transformer - correct?
@tmcgahey, for the outdoor box that you recommended, does it contain a transformer? And also, I assume it can also be installed inside correct?
Thanks!
