We just purchased a home from the bank, previous owner stripped the house including the sprinkler controller, so I have no idea what brand the previous controller was. One person stated that I have 8 zones, how do I know this. I have 3 bunches of colored wire coming through PVC pipe into the garage. I am currently looking to purchase the Rachio 3 WiFi Smart Alarm, but I need to know how many zones I have before the purchase. The second question, I live in rural area, so everything is either dish or WiFi, so I am limited on bandwidth, is this the controller that I should go with?
