The support from beginning to end is excellent with Wit-Motion. Currently using several HWT905-RS485 MPU9250 9-axis units to monitor the optimum angular degrees for my two solar arrays on my home property. I set the angle each month to ensure I am getting the maximum expose of sunlight in order to produce the maximum energy possible from my solar panels. Samick has been very helpful along with Kyle to ensure that I understand every aspect for my application. I currently am able to monitor the angle from my local PC in my home and adjust the arrays monthly via remote control. Having very accurate readings is paramount of the operation of this system.
