    Smart water set to off. Jumper is removed from rain sensor terminals and the hardwired rain sensor wires are not connected simulating the rain sensor has operated due to heavy rainfall. Held “Rain Delay” button on the wall unit for 5 seconds to turn the “SENS ON”
    Programs still run.
    In other words, the timer is ignoring the rain sensor. The only way I can delay it now is by using the rain delay on the app.
    Anybody else had this issue? Thanks

    I just hooked up the 57071 Wireless Rain and Freeze Sensor to my 57915 B-hyve Smart Indoor Irrigation Controller and it’s not recognizing the rain sensor either. I can see the receiver sensing the signal when I manually click the rain delay button or physically press down on the sensor, but it keeps on watering. I don’t know if I need to have smart watering turned off or what, but none of the manuals are very helpful. Need to call tech support later.

    Hope you have better luck with support than I had. Thats why I’m on the forum……….

    I ended up getting a call back. The lady on the phone ran me through a troubleshooting guide and there was a lot to try out. Some I already tried out, but in the end I just don’t think the sensor works with that controller or there is a procedure somewhere that is not documented. Because the unit came wired up with a jumper cable bridge the sensor terminals. Even when I removed that jumper, it still ran…which it shouldn’t.

    What I ended up doing was:
    1) Hook sensor red wires up to the 24V like usual.
    2) Left green unconnected like usual.
    3) Hooked sensor up as it there were no sensor terminals, which means disconnected original system’s white wire from COM port.
    4) Connecting sensor white wire to COM port.
    5) Connecting sensor yellow wire to white wire of original system with wire nut.

    By doing this you’re really placing the sensor in line with the system, which is how I think it’s essentially supposed to work. When I did this, the system could be telling the sprinkler to water, but the sensor is interrupting the connection and now sending power to the valves.

    I was thinking that the smart system and the sensor would communicate in a smarter way than that. In the end we’re home all the time and have cameras so we can be a better judge of how the lawn is doing. We have a well, no water restrictions, all our grass is over a couple inches of top soil, and then a LOT of sand, so it’s really hard to overwater it. So I’m just going to return the sensor, do a manual program, and turn the rain delay setting up to a higher percentage certainty setting.

    Hope that helps!

    “NOT” sending power to the valves.

    Excellent work around. Nice to see someone understands the difference between an electrical circuit for a water circuit! Thanks for the help.
