I used a Transformer with 70 watts rating(240v to 110v) to get this going since original PS is 110v and in Australia we use 240v. It will be a good idea for this company to supply 100-240v ac power supply since it is a global market now. 100 v ac is for Japan.
Initially I plugged this to the power point with out connecting my existing old Orbit 6 ch analog controller. Opened the app and ask to search for the Rachio, it found immediately and then start to work with my wifi ( Apple Airport Extreme) and got all blue leds on except the last one.. It said it had a problem and then gave 3 options, which I selected the 3rd, meaning 3 leds on and it seems 4th led is for the cloud and after that it fixed the issue and got all connected. I suspect cloud part may be due to my firewall. So far all good with the network side.
I removed my old Orbit and start to connect wires and after that, I used manual select of 2 min each zone to be on. It worked like a charm and fired all my 6 zones perfectly.
Controller does not recognise unconnected zones automatically and you have to switch them off via the app. Also it multiplied 16 zones with 2 minutes and gave wrong water consumption . They need to fix this issue.
Also need real time indicator to show which zone is on and need a run down counter to see how many minutes of time left with existing sprinkler that is active. One time I saw two zones on, which is a bug..
Also I use metric settings water usage is shown in Gallons .
Nice perfect controller and hope they improve the App..
