Thanks, going by memory I think the brand is Irritol it’s some wireless rain sensor but I’m not even sure if it works or not as the Orbit doesn’t really show anything about it, it just apparently turns off the program if it rains. Where I was confused setting it up though is that you can see in the picture it has a white and brown line connected to 2 sensor ports, but the Rachio has S1 and S2. If I put the brown in S1 and white in S2 for example, then go to accessories, it asks me to set up an accessory on S1 and another on S2 almost like I have too many wires. When I put the brown in S1 and white in S2, the Rachio immediately said something about rain sensor activated and programs won’t run. Is there a proper way to connect it?
Also you’re saying to just leave the 24 vac unplugged from both those connectors?
