Took a small 4" x 6" wicker style plastic basket, painted it white, cut a hole in the bottom of it the same size as the temp sensor, slid it up to the top, turned it 45 degrees, then took a couple of thin sticks and wedged them between the basket and the rain sensor, keeping a gap between the basket and sensor so the rain drains out. The temp sensor stays shaded now; time will tell if it made any difference!
