When Jeremy first introduced me to the Ecowitt WH51 sensors that measure 7 in of soil, I was amazed at how accurate and useful these sensors really are in comparison with everything else I have tried including Blumat $90 sensor that only gives you moisture but doesn't have any app nor any capability to send alerts or access via Bluetooth Wi-Fi like these Ecowitt devices have. So, I started using them on everything I have growing so I bought 12 of these sensors and I have to buy two Wi-Fi gateways because you can only add 8 moisture sensors to one Wi-Fi gateway which is not a big deal at all, but my question was how do I get better readings with larger containers 15 gallons or bigger and my question was answered shortly after when I got an email from Ecowitt that they are in process of making a new WH51L device with 1 Meter/1 Yard long wire attached to the sensor so it could be used in much larger/deeper containers and obviously it was a little more expensive than the previous WH51 units and they will be available in a couple of months.
