Yes, the Toro Precision Soil Sensor wires into the sensor port on Rachio, then uses wireless radio technology to connect to the sensor in the landscape. Same with the Rain Bird SMRT-Y, except the sensor wires directly into a valve. The Toro and Rain Bird soil sensors are well made and have heavy gauge stainless steel. I have taken a look at the products you mention and I doubt their long term viability. Buyer beware.
