Ecowitt Gateway with sensor makes the measurements (% soil moisture) of the wireless Ecowitt sensor (transmission via radio signal 868 Mhz) available in your Wifi. You can read the results from anywhere in the world and set warnings. 

The sensor is suitable for both indoor and outdoor use up to a distance of 100 metres between the Gateway and the sensor. The Gateway can control up to 8 sensors simultaneously. An e-mail is sent when the actual value drops below the set value.
