Rockwool Water Content Measuring

[Colordude]

Is anyone using Smart Bee's Water Content Sensor system to measure and/or control water their rockwool? Or using the system from Growtronix?
Anyone have feedback on these systems?
Just saw someone in texas has filed a 2007 patent infringement (on the idea of using a combined sensor system) on SmartBee, iPonics, Home Depot!, and others. . .what a dooshbag
