Moisture levels not matching sensor


#1

I switched my front lawn to Flex Daily and have a Toro moisture senor that Rachio recommended. I let the Flex daily start it’s primary watering. I then left the moisture sensor in the lawn at the recommended location per Toro for a few days and when it read 100% I set the moisture level for my Front Yard Zone on Rachio to Full.

After about 2 weeks I am noticing that the Toro moisture sensor and the Rachio Moisture level for my Front Yard Zone are off by 20 to 50% depending on the day. The Toro unit is showing much less moisture. The lawn appears to be ok but I am just trying to determine the cause of the difference.

Thank you

This is an interesting scenario. I have often wondered how the Toro Precision Soil Sensor would work with Rachio. It sounds like the two are fighting each other. Before I installed my Rachio, I had a Toro Evolution controller. One sensor port was for my soil sensor, which was installed in my full sun bermuda. In the backyard I had an ET sensor for fescue. I set the controller for a July schedule. Actually everything worked great, but there was no smartphone interface. I have found Rachio to be so accurate I have no need for a soil sensor or a rain sensor. The only way I can see Rachio to work with the Toro sensor is to bypass all smart features with the Rachio controller. But is this possible? I don’t know.

Hey @jnyphoto-

Are you zones accurately configured? Rachio could be tracking moisture incorrectly if it does not have the correct settings for each zone. It’s tricky because I don’t have any experience with the Toro sensor, and don’t know how accurate it typically is. Which sensor reading seems more correct to you based on the health of your lawn?
