People looking for Smart sprinkler controllers.
I did little bit of research and got rachio 8 zone 2nd gen.
I think both Rachio and Rainmachine are great controllers.
During my googling and talking to the customer service I found two codes for the controllers.
Rain Machine Take 30 dollars off the price of 239 from rain machine website
Rachio code is for 30 dollars off the price of 199.99.
Both are great, I went with Rachio because of lower price. But RainMachine is 12 zone, if someone needs more zones.
Hope this helps someone.
