I used a new library for the DHT from Rob Tillaart called DHTstable. When I installed the library it wound up in the incompatible section but It compiled ok so I sent it. The sensor began reading correctly right away. So far this is the only library I found that will work with the Uno Wifi rev 2 for DHT22 sensors. Now I need to figure out how to incorporate this library into my program that polls the five DS18b20 sensors, my burner fail contact and my zone valve status relays. And it would be nice to get the temp in F instead of C
