Check the Region and Factor (or whatever it's called) settings on it. I've found that region 3 and the factor set somewhere between 7 and 9 work best for Tx. A lot of people will set them to region 4 thinking they'll get more water but that actually does the opposite.
Also, they work on a 3 day average so a couple of cloudy days will effect them down. I don't think the sensor is a thermometer but rather just senses whether or not it's sunny.
They're better than just a rain sensor but they're still pretty crude.
