I had trouble getting the main outdoor sensor to connect to the indoor console. The reason I had trouble was that I didn't read the instructions, which clearly say to put batteries into the outdoor sensors before powering up the display. Being eager to see the display light up, I did it in the opposite order. Powering off the display and then powering up again (after batteries were placed into the outdoor sensors) made everything come online normally.

It was a very easy hookup to my router, along with entering Weather Underground and Weather Cloud information. I really can't say anything about accuracy, since I have nothing to compare the readings to.

I do have one suggestion for the Kentfaith designers, if they read these things. The mounting pole fits into the main sensor and mounting bracket in only one orientation, so that adjusting the direction of the sensor has to be done at the mounting bracket. I actually jerry-rigged it using a small length of 1/2" PVC pipe, so that I could make fine adjustments to the sensor's direction. A round mounting pole with a lock screw might work better.
Overall, I am very pleased with the weather station.
