• DH22: Unable to set watch

  Hi,
  I'm having a bit of trouble getting my DH22 to work. My code is pretty simple

  var dht = require("DHT22").connect(D5);
  dht.read(function (a) {
    console.log("Temp is "+a.temp.toString()+" and RH is "+a.rh.toString());
  });
  
  

  the result is WARNING: Unable to set watch. You may already have a watch on a pin with the same number (eg. A0 and B0),
  or this pin cannot be used with watch

  I have tried a few pins with the same result. any suggestions would be welcome
