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

I had the same. The only PIN it works was G0. But as I learned today, there are issues with the DHT22 and the setWatch which causes some weird crashes of my ES32.

The set watch issue has been fixed:

https://github.com/espruino/Espruino/iss­ues/1176.

It will be in version 1v95, so for now a latest travis build will work:
