  • The products sold on 鶹.co.uk and 鶹.de are 868 MHz;

ecowitt QA2

2. What if purchase the wrong Frequency products?

  • Please note that the all the products sold on amazon.ca are 915 MHz.
  • If one product you want to purchase is out of stock on amazon.ca or amazon.com, please DO NOT purchase it on other countries' amazon sites because different countries sell different frequency products. If the sensors and the gateway/receivers are different in frequency, they could not work together.

QA3

3. Can the WH51 be used alone? Can it display the soil moisture readout?

  • This is a good question. Ecowitt WH51 soil moisture sensor is only a sensor, which means WH51 is just an accessory, can not be used alone and could not directly display the data.
  • You need to separately purchase GW1100 WiFi gateway or other ecowitt console display to pair with it.
